Description

本発明は、画像形成装置、および画像形成装置に使用される現像剤収納容器、現像剤収納ユニット、現像装置、カートリッジに関するものである。   The present invention relates to an image forming apparatus and a developer storage container, a developer storage unit, a developing device, and a cartridge used in the image forming apparatus.

ここで画像形成装置とは、例えば電子写真画像形成プロセスを用いて記録媒体に画像を形成するもので、例えば電子写真複写機、電子写真プリンター(例えば、LEDプリンター、レーザービームプリンタ等)、電子写真ファクシミリ装置等が含まれる。   Here, the image forming apparatus is an apparatus that forms an image on a recording medium using, for example, an electrophotographic image forming process. For example, an electrophotographic copying machine, an electrophotographic printer (for example, an LED printer, a laser beam printer, etc.), an electrophotography, and the like. A facsimile machine is included.

またカートリッジとは、少なくとも現像手段と現像剤を収納した現像装置を一体的に構成して画像形成装置本体に着脱可能にしたものや、現像装置と少なくとも感光体を有する感光体ユニットを一体的に構成して画像形成装置本体に着脱可能にしたものを言う。   Also, the cartridge is a unit in which at least the developing means and the developing device containing the developer are integrally configured so as to be detachable from the main body of the image forming apparatus, or the developing device and the photosensitive unit having at least the photosensitive member are integrated. This is configured to be detachable from the image forming apparatus main body.

また現像剤収納容器および現像剤収納ユニットは、前記画像形成装置または前記カートリッジに収納されるものである。現像剤収納容器及び現像剤収納ユニットは、少なくとも現像剤を収納するための可撓性容器を備えている。   The developer storage container and the developer storage unit are stored in the image forming apparatus or the cartridge. The developer storage container and the developer storage unit include at least a flexible container for storing the developer.

従来の電子写真形成プロセスを用いた電子写真画像形成装置には、電子写真感光体及びそれに作用するプロセス手段を一体的にカートリッジ化して、このカートリッジを電子写真画像形成装置本体に着脱可能とするプロセスカートリッジ方式が採用されている。   In a conventional electrophotographic image forming apparatus using an electrophotographic image forming process, an electrophotographic photosensitive member and process means acting on the electrophotographic photosensitive member are integrally formed into a cartridge, and the cartridge can be attached to and detached from the main body of the electrophotographic image forming apparatus. A cartridge system is adopted.

このようなプロセスカートリッジでは、図52で示す様に現像剤(トナー、キャリア等)を収納する現像剤収納枠体31に設けた開口部を封止部材で封止している。そして、使用時に封止部材であるトナーシール32の接合部33を引き剥がすことで開口部が開封され現像剤の供給が可能となる方式が広く採用されている(特許文献1、図13)。   In such a process cartridge, as shown in FIG. 52, the opening provided in the developer storage frame 31 for storing the developer (toner, carrier, etc.) is sealed with a sealing member. A method is widely employed in which the opening portion is opened by peeling the joint portion 33 of the toner seal 32 that is a sealing member during use so that the developer can be supplied (Patent Document 1, FIG. 13).

またプロセスカートリッジ製造時に現像剤の充填工程でプロセスカートリッジの機内に現像剤が飛散する問題に対して変形可能な内部容器を用いたものが考案されている(特許文献1)。   Further, there has been devised an apparatus using a deformable inner container for the problem that the developer scatters in the process cartridge in the developer filling process at the time of manufacturing the process cartridge (Patent Document 1).

特開平4−66980JP-A-4-66980

しかし特許文献1のように、内部容器の内側に弾性部材を設けることは製造上困難であり、またコストがかかってしまう場合がある。   However, as in Patent Document 1, it is difficult to manufacture the elastic member inside the inner container, and the cost may be increased.

そこで本発明の目的は、従来とは異なる構成において、可撓性容器を用いた現像剤収納ユニットであって、開封性の優れた現像剤収納ユニットを提案するものである。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to propose a developer storage unit using a flexible container and having an excellent unsealing property in a configuration different from the conventional one.

上記目的を達成するため、本出願に係る発明の構成の一つは以下のようなものである。   In order to achieve the above object, one of the configurations of the invention according to the present application is as follows.

現像剤を収納する為の現像剤収納容器であって、前記現像剤収納容器は、前記現像剤を入れるための注入口と前記現像剤を排出するための複数の開口部とを備えた可撓性容器と、前記複数の開口部を封止した状態で前記可撓性容器に取り付けられた、移動されることによって前記複数の開口部を露出することが可能な封止部材と、を有し、前記複数の開口部は、前記複数の開口部の露出の進む開封方向に対して垂直方向にずれて配置されていることを特徴とする現像剤収納容器である。   A developer storage container for storing a developer, wherein the developer storage container is a flexible container including an inlet for containing the developer and a plurality of openings for discharging the developer. And a sealing member attached to the flexible container with the plurality of openings sealed so that the plurality of openings can be exposed by being moved. The plurality of openings are arranged to be shifted in the vertical direction with respect to the opening direction in which the plurality of openings are exposed.

以上説明したように、本発明によれば、現像剤を収納するための可撓性容器を用いた収納容器、現像剤収納容器又は現像剤収納ユニットにおいて、可撓性容器開口部を封止する封止部材の開封特性を向上させることができる。   As described above, according to the present invention, a flexible container opening is sealed in a storage container, a developer storage container, or a developer storage unit using a flexible container for storing a developer. The opening characteristic of the sealing member can be improved.

Here, the relationship between the developer storage container 37 for storing the developer and the developer storage container 26 for storing the developer will be described.

まず図30(a)に示すように現像剤を収納するための現像剤収納容器37には現像剤が充填されておらず現像剤を入れる為の注入口39がある。   First, as shown in FIG. 30 (a), the developer container 37 for containing the developer is not filled with the developer and has an injection port 39 for containing the developer.

次に図30(b)で示すように現像剤を収納するための現像剤収納容器37の現像剤を入れる為の注入口39から現像剤を充填する。また現像剤袋16の可撓性により入れる為の注入口39は充填装置に合わせて変形可能であり現像剤の飛散なく充填が容易になる。充填に際しては、公知のオーガー式充填装置を使用して行うが、同様の機能を有する他の方法を用いてもかまわない。   Next, as shown in FIG. 30B, the developer is filled from the inlet 39 for containing the developer in the developer container 37 for containing the developer. Moreover, the injection port 39 for inserting due to the flexibility of the developer bag 16 can be deformed according to the filling device, and the filling of the developer bag 16 is facilitated without scattering of the developer. The filling is performed using a known auger type filling device, but other methods having the same function may be used.

次に図30(c)で示すように現像剤を入れる為の注入口39を接合し封止する。現像剤を入れる為の開口部の接合部39aの接合は、本実施例では超音波で接合しているが他に熱やレーザーなどで接合してもよい。   Next, as shown in FIG. 30C, the injection port 39 for containing the developer is joined and sealed. In the present embodiment, the bonding portion 39a of the opening for putting the developer is bonded by ultrasonic waves, but may be bonded by heat or laser.

そして充填する為の開口部の接合部39aの接合が完了すると現像剤は封入され現像剤を収納した現像剤収納容器26となるのである。   When the joining of the joining portion 39a of the opening for filling is completed, the developer is sealed and becomes the developer storage container 26 containing the developer.

なお充填する為の注入口39の位置や大きさは現像剤の充填装置やプロセスカートリッジAの形状等に合わせて適宜配置すればよい。   The position and size of the filling port 39 for filling may be appropriately arranged in accordance with the developer filling device, the shape of the process cartridge A, and the like.

(現像装置内に現像剤袋を有する効果)
現像剤を収納した現像剤収納容器26が袋形態をとることにより現像剤をユニットとして扱える。そのため現像剤充填工程をプロセスカートリッジAのメインの組立工程(製造ライン)から分離できる。これによりプロセスカートリッジAのメインの組み立て工程(製造ライン)に現像剤が飛散することがなくなり製造ラインの清掃などのメンテナンスを削減することができる。組立工程時に現像剤の飛散がなくなることにより現像剤を充填した後のプロセスカートリッジAの清掃工程を省くことができる。
(Effect of having a developer bag in the developing device)
The developer storage container 26 storing the developer takes the form of a bag, so that the developer can be handled as a unit. Therefore, the developer filling process can be separated from the main assembly process (production line) of the process cartridge A. As a result, the developer is not scattered in the main assembly process (manufacturing line) of the process cartridge A, and maintenance such as cleaning of the manufacturing line can be reduced. By eliminating the scattering of the developer during the assembly process, the process cartridge A cleaning process after filling the developer can be omitted.

また現像剤袋16の充填工程においても現像剤袋16は可撓性を有しており充填のための注入口39も柔らかいため飛散少なく容易に封止できる。   Also in the filling step of the developer bag 16, the developer bag 16 has flexibility and the filling port 39 for filling can be soft and can be easily sealed with little scattering.

また現像剤を収納した現像剤収納容器26は可撓性を有しているため枠体の形状に倣わせて組むことができる。   Further, since the developer storage container 26 storing the developer has flexibility, it can be assembled following the shape of the frame.

また充填工程において現像剤収納容器37は可撓性を有するため断面を変形させて容積を増やして充填することができるので充填時には充填量を増やすことができる。   In addition, since the developer container 37 has flexibility in the filling step, it can be filled by deforming the cross section to increase the volume, so that the filling amount can be increased during filling.

また現像剤充填前の現像剤収納容器37は可撓性を有しているため小さく(薄く)することができて、樹脂の構造体である枠体に比べ充填前の保管時の保管スペースを小さくすることができる。   Further, since the developer container 37 before filling with the developer has flexibility, it can be made small (thin), and the storage space at the time of filling before filling is larger than that of the frame which is a resin structure. Can be small.

<現像剤袋の構成>
図3、図4に示すように現像剤袋16は内部に現像剤を収納しており形状が変形可能な袋状のものであり、収納した現像剤を排出するために排出部35に複数の開口部35aを備えている。
<Configuration of developer bag>
As shown in FIGS. 3 and 4, the developer bag 16 is a bag-shaped bag that contains a developer and can be deformed. A plurality of discharge bags 35 are provided in the discharge portion 35 to discharge the stored developer. An opening 35a is provided.

また現像剤袋16は第一の枠体17、第二の枠体18枠体に固定されている現像剤袋固定部(被固定部)16d、16eを有している。   The developer bag 16 has developer bag fixing portions (fixed portions) 16d and 16e fixed to the first frame 17 and the second frame 18 frame.

(現像剤袋の素材、通気性)
図29は現像剤収納容器26の断面説明図である。図29(a)で示すように現像剤袋16は排出部35を有し通気性を有さないシート16uと、通気部となる通気性を有するシート16sを貼り合わせて現像剤袋16は構成されている。
(Developer bag material, breathability)
FIG. 29 is an explanatory cross-sectional view of the developer storage container 26. As shown in FIG. 29 (a), the developer bag 16 is configured by laminating a sheet 16u having a discharge portion 35 and no air permeability and an air permeable sheet 16s serving as a ventilation portion. Has been.

ここで通気部16sの通気度は収納する現像剤の大きさ(粉体の粒径)との兼ね合いで現像剤が現像剤袋16の外に漏れないものを適宜選定すれば良い。   Here, the air permeability of the ventilation portion 16s may be appropriately selected so that the developer does not leak out of the developer bag 16 in consideration of the size of the developer to be stored (particle size of the powder).

通気部16sの素材としてポリエチレンテレフタレート(PET)、ポリエチレン(PE)、ポリプロピレン(PP)等で、厚さは0.03〜0.15mmの不織布などが好ましい。また通気部16sの素材が不織布ではなくても現像剤袋16に収納する現像剤等の粉体よりも微細な穴が開いているものでも良い。   The material of the ventilation portion 16s is preferably polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP) or the like, and a nonwoven fabric having a thickness of 0.03 to 0.15 mm. The material of the ventilation portion 16s may not be a non-woven fabric, but may be one having finer holes than the powder of developer or the like stored in the developer bag 16.

また通気部16sの配置は本実施例では図3、図29に示すように第二の枠体18側に現像剤袋16の長手方向全域にわたり通気部16sを配している。なお図29(b)に示すように通気部16sは現像剤袋16全体を16sで構成してもよい。   Further, in the present embodiment, as shown in FIGS. 3 and 29, the ventilation portion 16s is arranged on the second frame 18 side over the entire length of the developer bag 16 in the longitudinal direction. As shown in FIG. 29 (b), the ventilation portion 16s may comprise the entire developer bag 16 with 16s.

なお通気部16s以外の現像剤袋16の素材としては後述する現像剤排出時の効率を良くするように可撓性を有するものが好ましい。また通気部16sの素材に可撓性をもたせても良い。   The material of the developer bag 16 other than the ventilation portion 16s is preferably flexible so as to improve the efficiency when the developer is discharged as described later. Further, the material of the ventilation portion 16s may be made flexible.

(現像剤袋が通気性を有する効果)
このように現像剤袋16に通気性をもたせる理由としては、製造時、ユーザーがカートリッジAを使用するまでの物流時、および保管時に対応する為である。
(Effect of developer bag having air permeability)
The reason for providing the developer bag 16 with air permeability in this way is to cope with the time of manufacture, the distribution until the user uses the cartridge A, and the time of storage.

まず製造時の理由としては、現像剤袋16を枠体17、18に組み込み易いように現像剤袋16を変形、縮小可能とする為である。現像剤袋16に通気部16sが無い場合は現像剤袋16に現像剤を充填した状態(袋を閉じた状態)の大きさから変えられず、そのため変形もさせにくい。そのため組立に時間を要したり、工程が複雑化する。そこで現像剤袋16の少なくとも一部に通気性を持たせると現像剤袋16に現像剤を充填して袋を閉じた状態の大きさから変える事が可能となり組み立てしやすくなる。   First, the reason for manufacturing is that the developer bag 16 can be deformed and reduced so that the developer bag 16 can be easily incorporated into the frames 17 and 18. When the developer bag 16 does not have the ventilation portion 16s, the developer bag 16 cannot be changed in size from the state in which the developer bag 16 is filled with the developer (the bag is closed), and therefore, the developer bag 16 is not easily deformed. Therefore, time is required for assembly and the process becomes complicated. Therefore, if at least a part of the developer bag 16 is made air permeable, the developer bag 16 can be filled with the developer and the size of the bag can be changed to facilitate assembly.

次に物流時および保管時の理由としては、プロセスカートリッジAの輸送時および保管時に異なる気圧の変化に対応するためである。物流などで製造時より低い気圧環境下となる場合や、製造時より高い温度となる保管される場合などにより現像剤袋16内外の気圧差が発生する。そのため現像剤袋16が膨張することで現像剤袋16と接する各部品が変型や破損の恐れがある。そのための物流時や保管時に気圧や温度の管理が必要となり設備、コストがかかる。しかし一部に通気性を持たせることにより気圧による現像剤袋16内外の気圧差による問題を解消できるのである。   Next, the reason for distribution and storage is to cope with different changes in atmospheric pressure during transport and storage of the process cartridge A. A pressure difference between the inside and outside of the developer bag 16 is generated when the air pressure environment is lower than that at the time of manufacture due to physical distribution or when the temperature is higher than that at the time of manufacture. Therefore, when the developer bag 16 is inflated, each component in contact with the developer bag 16 may be deformed or damaged. For this purpose, it is necessary to manage the atmospheric pressure and temperature at the time of distribution and storage, which requires equipment and cost. However, by providing a part of the air permeability, the problem caused by the pressure difference between the inside and outside of the developer bag 16 due to the pressure can be solved.

また通気性を有する不織布に排出部35、排出部35周囲の接合部22を設けた場合は、開封時に封止部材19の剥離に伴い不織布の繊維がとれて現像剤の中に入り画像に悪影響を与える恐れがある。そのため通気性を有するシート16sとは異なるシート16uに排出部35を設けることにより前述のような不織布の繊維が抜け落ちる事がなくなる。   In addition, when the discharge portion 35 and the joint portion 22 around the discharge portion 35 are provided in a breathable nonwoven fabric, the fibers of the nonwoven fabric are taken off as the sealing member 19 is peeled off at the time of opening to adversely affect the image. There is a risk of giving. Therefore, by providing the discharge portion 35 on the sheet 16u different from the sheet 16s having air permeability, the fibers of the nonwoven fabric as described above are prevented from falling off.

また通気部16sから脱気しながら現像剤を充填することにより充填密度を上げることができる。   Further, the filling density can be increased by filling the developer while deaerating from the ventilation portion 16s.

(現像剤袋の排出部構成)
図3、図10に示す様に現像剤袋16は内部の現像剤を排出するための複数の開口部35a、および複数の開口部35aを定義する連結部35bからなる現像剤排出部35を有している。そして封止部材19により、排出部35の周囲を接合部22で連続して取り囲み開封可能に接合し現像剤袋16に収納する現像剤を封止している。
(Developer bag outlet configuration)
As shown in FIG. 3 and FIG. 10, the developer bag 16 has a developer discharge portion 35 including a plurality of openings 35a for discharging the developer inside and a connecting portion 35b defining the plurality of openings 35a. doing. The sealing member 19 continuously encloses the periphery of the discharge portion 35 with the joint portion 22 and joins it so that it can be opened, and seals the developer stored in the developer bag 16.

(現像剤袋の接合部構成)
接合部22は長い方向(方向F)に2本、短い方向(方向E)に2本とで囲んだ「ロの字」形状で連続しているため排出部35の封止を可能としている。
(Developer bag joint configuration)
Since the joining portions 22 are continuous in a “b” shape surrounded by two in the long direction (direction F) and two in the short direction (direction E), the discharge portion 35 can be sealed.

ここで長い方向(方向F)に溶着された2本の接合部のうち先に開封されるものを第一の接合部22a、後に開封されるものを第二の接合部22bとする。本実施形態では、封止部材19の表面に沿ってみた場合に、後述する返し部19d(又は被係合部19b)に近い側の接合部を第一の接合部22aである。また、開口部を挟んで第一の接合部22aに対向する接合部が第二の接合部22bである。また短い方向の接合部を短手接合部22cとする。   Here, of the two joints welded in the long direction (direction F), the first joint 22a is opened first, and the second joint 22b is opened later. In this embodiment, when it sees along the surface of the sealing member 19, the junction part near the return part 19d (or engaged part 19b) mentioned later is the 1st junction part 22a. Further, the joint portion facing the first joint portion 22a across the opening is the second joint portion 22b. Also, the short direction joint is referred to as a short joint 22c.

本実施例において開封方向は方向Eである。開封方向は次のように定義する。封止部材19を移動させて開封を行う場合に、開口部35aを挟んだ第一の接合部22aと第二の接合部22bとでは、第一の接合部22aが先に開封(剥離)される。このように、先に開封される第一の接合部22aから第二の接合部22bに向かう方向を開封方向Eとする。   In this embodiment, the opening direction is the direction E. The opening direction is defined as follows. When opening by moving the sealing member 19, the first joint 22a is first opened (peeled) at the first joint 22a and the second joint 22b with the opening 35a interposed therebetween. The In this way, the direction from the first joint 22a opened first to the second joint 22b is defined as an opening direction E.

なお現像剤袋16から封止部材19をE方向に開封する時(剥離する時)に、微視的に見ると第一の接合部22aや第二の接合部22bの中においても開封力による現像剤袋16の変形により矢印F方向にも剥離が進む場合がある。しかしながら、本実施例における開封方向は、このような微視的な開封の方向を指すものではない。   When the sealing member 19 is unsealed from the developer bag 16 in the E direction (when peeled), when viewed microscopically, even in the first joint portion 22a and the second joint portion 22b, Due to the deformation of the developer bag 16, peeling may also proceed in the direction of arrow F. However, the opening direction in the present embodiment does not indicate such a microscopic opening direction.

(現像剤袋の開口部の配置)
次に図10、図11、図30を用いて開口部35aの配置について説明する。開口部35aを封止するとともに移動されることによって開口部35aを露出する封止部材19の移動方向(開封部材20に引っ張られる方向)はDである。封止部材19の移動により開口部35aは開封方向Eの方向に露出が進む。以下封止部材19の移動方向をDとする。開封方向Eに対して垂直な方向Fにずれて複数の開口部35aおよび連結部35bを配置している。また封止部材19は、開封部材20を回転させて巻きとる構成としているが、前記の方向Fは開封部材20の回転軸の軸線と同じ方向である。
(Arrangement of developer bag opening)
Next, the arrangement of the openings 35a will be described with reference to FIG. 10, FIG. 11, and FIG. The moving direction of the sealing member 19 that exposes the opening 35a by sealing and moving the opening 35a (the direction pulled by the opening member 20) is D. The opening 35a is exposed in the opening direction E by the movement of the sealing member 19. Hereinafter, the moving direction of the sealing member 19 is D. A plurality of openings 35a and connecting portions 35b are arranged in a direction F perpendicular to the opening direction E. Further, the sealing member 19 is configured to rotate and wind the opening member 20, but the direction F is the same as the axis of the rotation axis of the opening member 20.

ここで現像ローラ13の回転軸方向と複数の開口部35aの並ぶ方向Fを揃えるのは、現像剤を排出時に現像ローラ13の長手方向全体に現像剤が偏りなく供給され易くするためである。   The reason why the rotation axis direction of the developing roller 13 is aligned with the direction F in which the plurality of openings 35a are arranged is to make it easy to supply the developer to the entire longitudinal direction of the developing roller 13 without discharge.

ここで複数の開口部35aはFの方向にずれて配置されているため排出部35は方向Fに長く、方向Eに短いものとなる。つまり方向Fにおける複数の開口部35aの端から端までの距離は、方向Eにおける開口部35aの端から端までの長さより長い。   Here, since the plurality of openings 35a are arranged so as to be shifted in the direction F, the discharge portion 35 is long in the direction F and short in the direction E. That is, the distance from end to end of the plurality of openings 35a in the direction F is longer than the length from end to end of the openings 35a in the direction E.

このように開封方向Eに対して垂直な方向Fにずれて複数の開口部35aを配置している排出部35は方向Fに長く方向Eに短いものとなるため開封に要する距離が、長い方向Fに開封するより短くてすむため開封に要る時間も短くできる。   Thus, since the discharge part 35 which has shifted | deviated to the direction F perpendicular | vertical with respect to the opening direction E and has arrange | positioned the some opening part 35a becomes long in the direction F and short in the direction E, the distance required for opening is a long direction. The time required for opening can be shortened because it is shorter than opening to F.

また排出部35を覆う封止部材19を開封部材20で巻きとる構成としている。開封部材20の回転軸方向と開封方向Eに対して略垂直な方向Fは同じ方向とすることで、封止部材19の巻きとり距離、時間を短くできる。   In addition, the sealing member 19 that covers the discharge portion 35 is wound around the opening member 20. The winding distance and time of the sealing member 19 can be shortened by setting the rotation axis direction of the opening member 20 and the direction F substantially perpendicular to the opening direction E to be the same direction.

(現像剤袋の開口部の形状、方向)
実施例1の複数の開口部35aはそれぞれ丸形状である。排出性を考慮すると開口部35aの面積は大きい方が良い。また開口部を定義する連結部35bは、現像剤袋16の強度を高めるため大きい(太い)方が良い。よって開口部35aの面積と連結部35bの面積は、排出部35の材質、厚み、また後述する開封時のピーリング強度との力関係等によりバランスをとる必要があり適宜選定すれば良い。また開口部35aの形状も丸以外に四角等の多角形や後述する第二の実施例の図18に示すような長丸等でもよい。
(Shape and direction of developer bag opening)
Each of the plurality of openings 35a according to the first embodiment has a round shape. Considering the discharge performance, the area of the opening 35a should be large. The connecting portion 35b that defines the opening is preferably large (thick) in order to increase the strength of the developer bag 16. Therefore, the area of the opening 35a and the area of the connecting portion 35b need to be balanced depending on the material relationship between the material and thickness of the discharge portion 35, the peeling strength at the time of opening, which will be described later, and the like. Further, the shape of the opening 35a may be a polygon such as a square other than a circle, or an elongated circle as shown in FIG. 18 of the second embodiment described later.

なお開口部35aの配置は開封方向Eに対して垂直な方向Fに対してずれていれば良く、図28(c)に示すように開口部35aが開封方向Eに垂直な方向Fに重なっていても、図28(d)に示すように重なっていなくても後述する連結部35bの効果がある。   The arrangement of the opening 35a only needs to be shifted with respect to the direction F perpendicular to the opening direction E, and the opening 35a overlaps the direction F perpendicular to the opening direction E as shown in FIG. However, as shown in FIG. 28 (d), there is an effect of the connecting portion 35b described later even if they do not overlap.

また開口部35aの方向は画像形成時の姿勢で収納する現像剤を排出しやすいようになっているのが好ましい。そのため、画像形成時の姿勢において、開口部35aは、重力方向の下方向に開くように配置される。ここで、開口部35aが重力方向の下方向に開くとは、開口部35aの開口の向きが重力方向下方向の成分を持つことを指す。   The direction of the opening 35a is preferably such that the developer stored in the orientation at the time of image formation can be easily discharged. Therefore, in the posture at the time of image formation, the opening 35a is arranged so as to open downward in the gravity direction. Here, opening the opening 35a downward in the direction of gravity means that the direction of the opening of the opening 35a has a component in the downward direction of the gravity.

(現像剤袋と枠体の固定)
図3、図4に示す様に現像剤袋16は二つの固定部16d、16eにより第一の枠体17、第二の枠体18の内部に固定される。
(Fixing of developer bag and frame)
As shown in FIGS. 3 and 4, the developer bag 16 is fixed inside the first frame 17 and the second frame 18 by two fixing portions 16d and 16e.

(第一の固定部)
まず一つ目の固定部として、後述する封止部材19を現像剤袋16から開封する時に力を受ける現像剤袋16の第一の固定部16dを設けている。複数の開口部35aが配置されている方向Fと平行に、固定部16dは複数個設けられている。なお固定部16dはこのように複数個設けられる以外に方向Fと平行に長いひとつのものでも良い。(不図示)
また第一の固定部16dの位置は現像剤袋16の開口部35aの近傍に設けられている。
(First fixed part)
First, as a first fixing portion, a first fixing portion 16d of the developer bag 16 that receives a force when a sealing member 19 described later is opened from the developer bag 16 is provided. A plurality of fixed portions 16d are provided in parallel with the direction F in which the plurality of openings 35a are arranged. In addition, the fixed part 16d may be one long in parallel with the direction F other than being provided in plural. (Not shown)
The position of the first fixing portion 16d is provided in the vicinity of the opening 35a of the developer bag 16.

また現像剤袋の第一の固定部16dは枠体の第一の固定部18aに固定されている。   The first fixing portion 16d of the developer bag is fixed to the first fixing portion 18a of the frame.

第一の固定部16dは現像剤袋16の開封時の為に必要な固定部所であり、その作用や配置に関しては開封の説明で後述する。   The first fixing portion 16d is a fixing portion necessary for opening the developer bag 16, and its operation and arrangement will be described later in the description of opening.

(第二の固定部)
また二つ目の固定部として、現像剤袋16が下方、もしくは現像ローラ13、現像剤供給ローラ23の方へ移動するのを防ぐため第二の固定部16eを設けている。
(Second fixed part)
As a second fixing portion, a second fixing portion 16e is provided to prevent the developer bag 16 from moving downward or toward the developing roller 13 and the developer supply roller 23.

第二の固定部16eを設けているのは、2つの理由がある。第一の理由としては現像剤袋の第二の固定部16eが現像剤袋16を画像形成時の姿勢で下方に移動しないようにするためである。そのため第二の固定部16eは画像形成時の姿勢で上方に配置するのが好ましい。   The second fixing part 16e is provided for two reasons. The first reason is that the second fixing portion 16e of the developer bag does not move the developer bag 16 downward in the posture at the time of image formation. For this reason, it is preferable that the second fixing portion 16e is disposed upward in the posture at the time of image formation.

また第二の理由としては、現像剤袋16が画像形成時に現像ローラ13や現像剤供給ローラ23に接触して画像を乱すことを防ぐためである。そのため現像ローラ13や現像剤供現像ローラ23から離れたところに現像剤袋16の第二の固定部16eを設ける事が好ましい。本実施例では現像剤袋の第二の固定部16eを図1に示すように現像ローラ13から離れた上方に配置している。   The second reason is to prevent the developer bag 16 from coming into contact with the developing roller 13 and the developer supplying roller 23 during image formation to disturb the image. Therefore, it is preferable to provide the second fixing portion 16e of the developer bag 16 at a position away from the developing roller 13 and the developer supply developing roller 23. In the present embodiment, the second fixing portion 16e of the developer bag is disposed above the developing roller 13 as shown in FIG.

また現像剤袋の第二の固定部16eは枠体の第二の固定部18bに固定される。   The second fixing portion 16e of the developer bag is fixed to the second fixing portion 18b of the frame body.

(現像剤袋と枠体の固定方法)
(第一の固定部の固定方法)
現像剤袋の第一の固定部16dの固定方法として、現像剤袋16の穴に、第二の枠体18のボスを通し、ボスをつぶす超音波カシメによる固定を用いている。図27(a)で示すように固定前には第二の枠体18の第一の固定部18aは円柱のボス形状をしており、現像剤袋16の第一の固定部16dは穴が開いている。そして組み立て工程を次に示す。
(How to fix the developer bag and frame)
(First fixing part fixing method)
As a fixing method of the first fixing portion 16d of the developer bag, fixing by ultrasonic caulking that passes the boss of the second frame 18 through the hole of the developer bag 16 and crushes the boss is used. As shown in FIG. 27A, before fixing, the first fixing portion 18a of the second frame 18 has a cylindrical boss shape, and the first fixing portion 16d of the developer bag 16 has a hole. is open. The assembly process is as follows.

まず第二の枠体18の第一の固定部18aの凸形状部に、現像剤袋16の第一の固定部16dの穴に通す(図27(b))。   First, the convex portion of the first fixing portion 18a of the second frame 18 is passed through the hole of the first fixing portion 16d of the developer bag 16 (FIG. 27B).

そして第二の枠体18の第一の固定部18aの先端を超音波カシメの工具34で溶かす((図27(c))。   And the front-end | tip of the 1st fixing | fixed part 18a of the 2nd frame 18 is melted with the tool 34 of an ultrasonic caulking ((FIG.27 (c)).

そして現像剤袋16の第一の固定部16dの穴より大きくなるように、第二の枠体18の第一の固定部18aの先端を変形させることで現像剤袋16を第二の枠体18に固定している(図27d)。   Then, the tip of the first fixing portion 18a of the second frame 18 is deformed so as to be larger than the hole of the first fixing portion 16d of the developer bag 16, so that the developer bag 16 is removed from the second frame. 18 (FIG. 27d).

(第二の固定部の固定方法)
図4に示すように現像剤袋の第二の固定部16eの固定方法は二つの枠体17、18による挟み込みを用いている。現像剤袋16に穴を開け現像剤袋の第二の固定部16eとし、第二の枠体18に凸部を設けて枠体の第二の固定部18bとする。
(Method for fixing the second fixing part)

Alternatively, the user may perform opening by holding and moving the opening member. In this embodiment, the unsealing member 20 is a rotating shaft provided on the frame, and the developer container 26 containing the developer is unsealed when the sealing member 19 engaged with the unsealing member 20 is pulled. .

(封止部材の封止部材連結部)
接合部22と封止部材係合部19bとの間を連結している部分が封止部材連結部19cである。封止部材連結部19cは開封部材20からの力を受けて接合部22を引き剥がすように力を伝達する部分である。
(Sealing member connecting part of sealing member)
A portion connecting the joint portion 22 and the sealing member engaging portion 19b is a sealing member connecting portion 19c. The sealing member connecting portion 19 c is a portion that receives the force from the opening member 20 and transmits the force so as to peel off the joint portion 22.

(封止部材連結部の折り返し)
ここで図12を用いて開封される瞬間において第一の接合部22aと第二の接合部22bとで形成された面N1とする。そして面N1に対して垂直で且つ第一の接合部22aを通る面N2とする。ここで開封部材20は、第一の接合部22aを通る面N2よりも第二の接合部22b側に配置されている。言い換えると封止部材19は、シート状である封止部材19の表面に沿って見たときに、接合部22と開封部材20との被係合部19bとの間の部分(連結部19c)で折り返されている返し部19dを有しているのである。返し部19dは折り目がついていても、折り目が付いていなくても良い。ここで封止部材19の返しの角度Qは90度以下が好ましい。折り返し角度Qは、現像剤袋16の接合部22の面と封止部材19の引っ張られる方向Dに沿った面の挟角Qである。
(Folding of sealing member connecting part)
Here, the surface N1 formed by the first joint portion 22a and the second joint portion 22b at the moment of opening using FIG. The surface N2 is perpendicular to the surface N1 and passes through the first joint 22a. Here, the unsealing member 20 is arranged on the second joint portion 22b side with respect to the surface N2 passing through the first joint portion 22a. In other words, the sealing member 19 is a portion between the joint portion 22 and the engaged portion 19b of the opening member 20 (the connecting portion 19c) when viewed along the surface of the sheet-like sealing member 19. It has a return portion 19d that is folded back at the end. The return part 19d may or may not have a crease. Here, the return angle Q of the sealing member 19 is preferably 90 degrees or less. The folding angle Q is an included angle Q between the surface of the joint portion 22 of the developer bag 16 and the surface along the direction D in which the sealing member 19 is pulled.

(封止部材の固定)
また封止部材19と開封部材20の固定は、本実施例において、第一の固定部16dと同様の超音波カシメで固定している。超音波カシメ以外に第一の固定部16dおよび第二の固定部16eの固定の手段と同様に熱溶着、超音波溶着、接着、枠体間への挟み込み、穴と凸による引っ掛け等でも良い。
(Fixing of sealing member)
The sealing member 19 and the unsealing member 20 are fixed by ultrasonic caulking similar to the first fixing portion 16d in this embodiment. In addition to ultrasonic caulking, thermal welding, ultrasonic welding, adhesion, pinching between frames, hooking by holes and projections, etc. may be used in the same manner as the means for fixing the first fixing portion 16d and the second fixing portion 16e.

(封止部材の易開封性を有する部分)
次に、接合部22の剥離力を所望の値にする方法について説明をする。本実施の形態では前記剥離力を所望の値(ここでは、トナー封止性を保てる範囲内でできるだけ小さい力)にするために、主に2つの方法をとっている。
(Part having the easy-opening property of the sealing member)
Next, a method for setting the peeling force of the joint portion 22 to a desired value will be described. In the present embodiment, two methods are mainly used in order to set the peeling force to a desired value (here, a force as small as possible within a range in which the toner sealing property can be maintained).

1つ目は、封止部材19に易開封を可能とするシーラント層を持つラミネート材を適用している。そして現像剤袋16の素材には前記シーラント層と溶着可能で可撓性のあるシート材質(例えば、ポリエチレンやポリプロピレン)を適用することで該接合部において易開封を可能とする方法である。シーラント層の処方及び貼り合わせる材質の組み合わせを変えることにより剥離力を所望の条件に合わせて調整させることが可能である。本実施例においてはJIS−Z0238の密封軟包装袋の試験において剥離強さが3N/15mm程度のものを用いている。   First, a laminate material having a sealant layer that allows easy opening is applied to the sealing member 19. The developer bag 16 is made of a flexible sheet material (for example, polyethylene or polypropylene) that can be welded to the sealant layer, thereby enabling easy opening at the joint. It is possible to adjust the peeling force according to desired conditions by changing the combination of the sealant layer and the material to be bonded. In this example, a JIS-Z0238 sealed flexible packaging bag having a peel strength of about 3 N / 15 mm is used.

2つ目は、図4、7に示すように現像剤袋16の排出部35を開封が進む方向(図中矢印E)に対して折り返された状態にする方法である。例えば図4の状態で開封部材20を回転(図中矢印C)させ封止部材19を開封部材20で引っ張られる方向(図中矢印D)に引っ張る。このようにすることで、現像剤袋16と封止部材19は図12に示すような現像剤袋16の接合部22の面と封止部材19の引っ張られる方向Dに沿った面の挟角Qが90度以下の傾斜剥離位置関係になる。従来傾斜剥離にすることにより両者の引き剥がしに必要な剥離力を低減できることが知られている。従って、前述したように封止部材19を開封が進む方向(図中矢印E)に対して折り返された状態にすることで接合部22部分の封止部材19と現像剤袋16が傾斜剥離の位置関係となり前記剥離力を低減するように調整することができる。   Second, as shown in FIGS. 4 and 7, the discharge portion 35 of the developer bag 16 is folded back in the opening direction (arrow E in the figure). For example, in the state of FIG. 4, the opening member 20 is rotated (arrow C in the figure), and the sealing member 19 is pulled in the direction in which the opening member 20 is pulled (arrow D in the figure). By doing so, the developer bag 16 and the sealing member 19 are sandwiched between the surface of the joint portion 22 of the developer bag 16 and the surface along the direction D in which the sealing member 19 is pulled as shown in FIG. The inclined peeling position relationship is such that Q is 90 degrees or less. Conventionally, it is known that the peeling force required for the peeling of both can be reduced by the inclined peeling. Therefore, as described above, the sealing member 19 and the developer bag 16 in the joint portion 22 are inclined and peeled by bringing the sealing member 19 into a folded state with respect to the direction of opening (arrow E in the figure). The positional relationship can be adjusted to reduce the peeling force.

<開封部材の構成>
開封部材20は封止部材19に力を与えて封止部材19を移動させ現像剤袋16から引き剥がす目的のものである。開封部材20は軸形状で両端を第二の枠体18に回転可能に支持されている支持部(不図示)と、封止部材19の被係合部19bを固定する係合部20bを有している。本実施例では開封部材20は四角い軸形状で、その四角い軸の一面に封止部材19の被係合部19bを係合部20bで係合している。
<Configuration of opening member>
The unsealing member 20 is for the purpose of applying a force to the sealing member 19 to move the sealing member 19 to peel it off from the developer bag 16. The unsealing member 20 has a shaft-shaped support portion (not shown) that is rotatably supported by the second frame 18 at both ends, and an engaging portion 20b that fixes the engaged portion 19b of the sealing member 19. doing. In this embodiment, the unsealing member 20 has a square shaft shape, and the engaged portion 19b of the sealing member 19 is engaged with one surface of the square shaft by the engaging portion 20b.

(開封部材、押圧部材、攪拌部材の兼用)
また現像剤袋16の外部から作用し現像剤袋16内部の現像剤を排出させる押圧部材21と、開封部材20はそれぞれ別の部材で行っても良いが、本実施例では開封部材20と押圧部材21を同じ部品で機能させている。
(Combination of opening member, pressing member and stirring member)
Further, the pressing member 21 that acts from the outside of the developer bag 16 and discharges the developer inside the developer bag 16 and the opening member 20 may be separate members, but in this embodiment, the opening member 20 and the pressing member 20 are pressed. The member 21 is made to function with the same parts.

また現像剤袋16から排出された現像剤を攪拌する機能と、開封部材20の機能をそれぞれ別の部品で行っても良いが本実地例では開封部材20に攪拌の機能を同じ部品で機能させている。   Further, the function of stirring the developer discharged from the developer bag 16 and the function of the opening member 20 may be performed by different parts, but in this practical example, the opening member 20 is made to function by the same part. ing.

(開封部材、押圧部材、攪拌部材兼用の効果)
このように開封部材20、押圧部材21、攪拌部材を兼用することで部品点数の削減によるコストダウン、省スペース化が可能となる。
(Effect of opening member, pressing member, stirring member)
Thus, by using the opening member 20, the pressing member 21, and the stirring member together, it is possible to reduce costs and save space by reducing the number of parts.

<現像剤収納袋の開封概要>
次に現像剤収納袋16の開封について図7、図8を用いて述べる。
開封のため開封部材20が封止部材19を引っ張る力を与える力点部20aと、引っ張られる現像剤袋16を固定する枠体の固定部18aを現像装置38は有している。
<Outline of opening the developer storage bag>
Next, the opening of the developer storage bag 16 will be described with reference to FIGS.
The developing device 38 has a force point portion 20a for applying a force for the opening member 20 to pull the sealing member 19 for opening and a frame fixing portion 18a for fixing the developer bag 16 to be pulled.

力点部20aとは開封の瞬間に封止部材19と開封部材20の接している部分の最も接合部22に近い部分である。図7(b)では開封部材20の角部20cが力点部20aである。また第二の枠体18の固定部18aは開封時の力による現像剤袋16の移動を抑制する固定部18cを有している。また接合部22から本実施例では枠体の第一の固定部18aと現像剤袋の第一の固定部16dは超音波カシメにより接合されており、図7(b)(c)、図8(a)で示す様に第一の固定部18aの超音波カシメ部分のうち接合部22に近い部分が固定部18cとなる。   The force point portion 20a is a portion closest to the joint portion 22 in a portion where the sealing member 19 and the opening member 20 are in contact with each other at the moment of opening. In FIG.7 (b), the corner | angular part 20c of the opening member 20 is the power point part 20a. The fixing portion 18a of the second frame 18 has a fixing portion 18c that suppresses the movement of the developer bag 16 due to the force at the time of opening. In the present embodiment, the first fixing portion 18a of the frame body and the first fixing portion 16d of the developer bag are joined by ultrasonic caulking from the joining portion 22, and FIGS. 7B, 7C, and 8 are used. As shown in (a), the portion close to the joint portion 22 of the ultrasonic caulking portion of the first fixing portion 18a becomes the fixing portion 18c.

次に図50を用いて開封部材20の駆動伝達について述べる。図50は開封部材20への駆動伝達を示す概略説明図である。なお図50では封止部材19や現像剤袋16等は省略している。まず開封部材20は両端を第一の枠体17に回転自在に支持されている。そして開封部材20の片側端部にはギア54が結合されている。またカートリッジAにはギア(52、53)が配置されている。そしてギア52は画像形成装置Bから駆動を受けるカップリング部52aを有している。   Next, drive transmission of the opening member 20 will be described with reference to FIG. FIG. 50 is a schematic explanatory view showing drive transmission to the opening member 20. In FIG. 50, the sealing member 19, the developer bag 16, and the like are omitted. First, the opening member 20 is rotatably supported by the first frame 17 at both ends. A gear 54 is coupled to one end of the opening member 20. The cartridge A is provided with gears (52, 53). The gear 52 has a coupling portion 52 a that receives driving from the image forming apparatus B.

画像形成装置Bには駆動手段51が設けられており、駆動手段51の先端にカートリッジAに駆動を伝達するカップリング51aを有している。   The image forming apparatus B is provided with a driving unit 51, and has a coupling 51 a that transmits driving to the cartridge A at the tip of the driving unit 51.

図50(a)で示す矢印方向にカートリッジAが画像形成装置B本体内へ装着される。次に図50(b)で示す矢印方向に駆動手段51が移動し、駆動手段51のカップリング部51aとギア52のカップリング52aが係合する。そして図50(c)で示すように画像形成装置Bの駆動手段51よりカートリッジAのギア52、ギア53、ギア54と駆動が伝わり開封部材20が回転する。 なお画像形成装置BからカートリッジAへの駆動伝達は凹凸によるカップリングに限らずギアによる係合等、駆動伝達ができる手段を用いればよい。   The cartridge A is mounted in the image forming apparatus B main body in the arrow direction shown in FIG. Next, the driving means 51 moves in the direction of the arrow shown in FIG. 50B, and the coupling portion 51a of the driving means 51 and the coupling 52a of the gear 52 are engaged. As shown in FIG. 50C, the driving means 51 of the image forming apparatus B transmits the drive to the gear 52, gear 53, and gear 54 of the cartridge A, and the opening member 20 rotates. Note that the drive transmission from the image forming apparatus B to the cartridge A is not limited to coupling by unevenness, and means that can transmit the drive, such as engagement by a gear, may be used.

そして図4で示すように開封部材20は駆動力が伝達され矢印Cの方向に回転する。   Then, as shown in FIG. 4, the unsealing member 20 is rotated in the direction of arrow C as the driving force is transmitted.

そして開封部材20の回転が進むことで封止部材19が引っ張られて第一の接合部22aの開封が始まる直前の状態を図5、図7(b)示す。回転に伴い開封部材20に被係合部19bで固定された封止部材19は四角い開封部材20の角部20c(力点部20a)により矢印Dの方向に引っ張られる。   And the state immediately before the sealing member 19 is pulled by the rotation of the opening member 20 and the opening of the first joint portion 22a starts is shown in FIGS. Along with the rotation, the sealing member 19 fixed to the opening member 20 by the engaged portion 19b is pulled in the direction of the arrow D by the corner portion 20c (power point portion 20a) of the square opening member 20.

封止部材19が引っ張られると接合部22を介して現像剤袋16が引っ張られる。すると現像剤袋16は第一の固定部16dに力が加わり固定部18cによって固定部18cから力点部20aに向けて現像剤袋16は引っ張られる。すると開封部材20の回転軸に垂直な断面において、第一の接合部22aは力部20aと固定部18cを結んだ線上に近づくように動く。このとき、矢印Dの方向において、開封部材20の回転軸に近い方から、開口部35a、第一の接合部22a、返し部19d、固定部18cの順に配置されている(図7(b))。そして封止部材19が第一の接合部22aと被係合部19bの間で折り返されているため第一の接合部22aの部分に矢印Dの方向に傾斜剥離するように力がかかる。そして第一の接合部22aの剥離が行われて排出部35の開封が始まる。   When the sealing member 19 is pulled, the developer bag 16 is pulled through the joint portion 22. Then, a force is applied to the developer bag 16 on the first fixing portion 16d, and the developer bag 16 is pulled by the fixing portion 18c from the fixing portion 18c toward the power point portion 20a. Then, in the cross section perpendicular to the rotation axis of the opening member 20, the first joint portion 22a moves so as to approach the line connecting the force portion 20a and the fixing portion 18c. At this time, in the direction of arrow D, the opening 35a, the first joining portion 22a, the return portion 19d, and the fixing portion 18c are arranged in this order from the side closer to the rotation axis of the opening member 20 (FIG. 7B). ). Since the sealing member 19 is folded back between the first joint portion 22a and the engaged portion 19b, a force is applied to the portion of the first joint portion 22a so as to be inclined and peeled in the direction of the arrow D. Then, the first joining portion 22a is peeled off and the discharge portion 35 is opened.

また角部20cと共に力点部20aも矢印Cの方向に移動し、角部20dと封止部材19が接すると角部20cから角部20dへ力点部は移動する。ここで図7(b)が力点部20aが角部(c)の状態を示し、図7(c)が更に開封部材20の回転が進み角部20dへ力点部が移った状態を示す。   In addition, the power point portion 20a moves in the direction of the arrow C together with the corner portion 20c, and when the corner portion 20d and the sealing member 19 contact each other, the power point portion moves from the corner portion 20c to the corner portion 20d. Here, FIG. 7B shows a state where the force point portion 20a is the corner portion (c), and FIG. 7C shows a state where the rotation of the unsealing member 20 further proceeds and the force point portion has moved to the corner portion 20d.

図6、図7(c)に示すように開封部材20の回転が進むに連れて開封が進むと共に返し部19dも矢印E方向に進む。そして更に開封が進み開口部35aが露出する。開口部35aが露出した後に第二の接合部22bの剥離に入る状態を図8(a)に示す。この時も第一の接合部22aの剥離と同様に封止部材19は力点部20aの方へ引っ張り、現像剤袋16は固定部18cの方向(矢印H)に踏ん張ろうとする。すると開封部材20の回転軸に垂直な断面において、第二の接合部22bは力部20aと固定部18cを結んだ線上に近づくように動く。そして第二の接合部22bの部分に矢印Dの方向の力がかかり第二の接合部が剥離する。そして第二の接合部22bが剥がされて開封が完了する(図8(b)、図9)。そして現像剤袋16内部の現像剤が排出部35の開口部35aを通り矢印Iの方向に排出される。   As shown in FIG. 6 and FIG. 7C, as the opening member 20 rotates, the opening progresses and the return portion 19 d also advances in the direction of arrow E. Further, the opening is further advanced and the opening 35a is exposed. FIG. 8A shows a state where the second joining portion 22b starts to be peeled after the opening 35a is exposed. At this time, similarly to the separation of the first joint portion 22a, the sealing member 19 is pulled toward the power point portion 20a, and the developer bag 16 tries to step in the direction of the fixing portion 18c (arrow H). Then, in the cross section perpendicular to the rotation axis of the opening member 20, the second joint portion 22b moves so as to approach the line connecting the force portion 20a and the fixing portion 18c. And the force of the direction of arrow D is applied to the part of the 2nd junction part 22b, and the 2nd junction part peels. And the 2nd junction part 22b is peeled and opening is completed (FIG.8 (b), FIG.9). The developer in the developer bag 16 is discharged in the direction of arrow I through the opening 35 a of the discharge portion 35.

このように開封部材20の回転により封止部材19が開封部材20に巻きとられて接合部22を開封するのである。封止部材19は回転で巻き取られるため開封部材20の移動に要するスペースは開封部材20の回転スペースがあれば良く、回転以外の移動により封止部材19を移動させる場合に比べ省スペース化する事が出来る。
また開封部材20をユーザーが回転させて封止部材19を巻き取って開口部35aを露出させても良い。しかし画像形成装置Bからの駆動により開封部材20の回転させて封止部材19を巻き取る方がユーザーの手を煩わせずより好ましい。
In this way, the sealing member 19 is wound around the opening member 20 by the rotation of the opening member 20 and the joint portion 22 is opened. Since the sealing member 19 is wound up by rotation, the space required for the movement of the opening member 20 only needs to be the rotation space of the opening member 20, and the space is saved compared to the case where the sealing member 19 is moved by movement other than rotation. I can do it.
Alternatively, the opening member 20 may be rotated by the user to wind up the sealing member 19 to expose the opening 35a. However, it is more preferable that the sealing member 19 is wound up by rotating the opening member 20 by driving from the image forming apparatus B without bothering the user.

また封止部材19が返し部19dを設けられていることで接合部22をせん断剥離せずに傾斜剥離とすることができ確実に開封できる。   In addition, since the sealing member 19 is provided with the return portion 19d, the joint portion 22 can be inclined and peeled without shearing and can be reliably opened.

また複数の開口部35aが並んでいる方向Fと略垂直方向の封止部材19の一端側に封止部材19を開封するための開封部材20に係合される被係合部(19b)が設けられることで確実に封止部材19を係合して開封することができる。   Further, an engaged portion (19b) engaged with the opening member 20 for opening the sealing member 19 is provided on one end side of the sealing member 19 in a direction substantially perpendicular to the direction F in which the plurality of openings 35a are arranged. By being provided, the sealing member 19 can be reliably engaged and opened.

また枠体に固定部18cを設けて、現像剤袋16を開封時に支持する事により柔らかく変形可能な現像袋16でも確実に開封可能となる。   Further, by providing the fixing portion 18c on the frame and supporting the developer bag 16 at the time of opening, the developing bag 16 that is soft and deformable can be reliably opened.

また開封時の現像剤の排出に関して、前述のように開封時に力点部20aと固定部18cで結んだ線上に接合部22が動く(図7(a)→図7(b)→図7(c)→図8(a))。この動きにより開口部35a周辺の現像剤が動かされ現像剤の凝集を崩す事が出来る。   Further, regarding the discharge of the developer at the time of opening, as described above, the joint portion 22 moves on the line connected by the force point portion 20a and the fixing portion 18c at the time of opening (FIG. 7 (a) → FIG. 7 (b) → FIG. → FIG. 8 (a)). By this movement, the developer around the opening 35a is moved and the aggregation of the developer can be broken.

また図34で示すように、開封部材20の回転方向は矢印C2の回転方向に回転させても開封可能である。このように開封部材20の回転方向は図4〜9で示すCの方向でも図34のC2の方向でも選択可能であり、設計に応じて適宜回転方向を選択すればよい。   As shown in FIG. 34, the opening direction of the opening member 20 can be opened even if it is rotated in the rotation direction of the arrow C2. Thus, the rotation direction of the unsealing member 20 can be selected in the direction C shown in FIGS. 4 to 9 or the direction C2 in FIG. 34, and the rotation direction may be appropriately selected according to the design.

(開封に関係する固定部の配置関係)
図4に示すように第一の接合部22bを確実に剥がすためには第一の接合部22bと固定部18cの間には次のような配置の関係が求められる。開封時には固定部18cに対して封止部材19を矢印Dの方向に開封部材20が引っ張る。この時、開封部材20による封止部材19の移動方向Dにおいて、固定部18cは開口部35aの上流側に設けられている。そのため矢印Hの方向に固定部18cの力が加わる。よって開封の力を加えた時に固定部18cと開封部材20の間で矢印Hと矢印Dの方向に引っ張られて第一の接合部22aに力を加え矢印Eの方向に開封が進む。このように封止部材19の移動方向Dにおいて上流に固定部18cを設けていなければ開封部材20が引っ張られた方向に現像剤袋16全体が引っ張られてしまい第一の接合部22aに力を加えることができず開封できない。
(Relationship of fixed parts related to opening)
As shown in FIG. 4, in order to surely peel off the first joint portion 22b, the following arrangement relationship is required between the first joint portion 22b and the fixing portion 18c. At the time of opening, the opening member 20 pulls the sealing member 19 in the direction of arrow D with respect to the fixed portion 18c. At this time, in the moving direction D of the sealing member 19 by the opening member 20, the fixed portion 18c is provided on the upstream side of the opening 35a. Therefore, the force of the fixing portion 18c is applied in the direction of the arrow H. Therefore, when an opening force is applied, the fixing member 18c and the opening member 20 are pulled in the directions of arrows H and D to apply force to the first joint portion 22a, and the opening proceeds in the direction of arrow E. As described above, if the fixing portion 18c is not provided upstream in the moving direction D of the sealing member 19, the entire developer bag 16 is pulled in the direction in which the opening member 20 is pulled, and force is applied to the first joint portion 22a. Cannot be added and cannot be opened.

このように封止部材19の移動方向Dにおいて上流に固定部18cを設けていることにより確実な開封が可能となるのである。   As described above, the fixing portion 18c is provided on the upstream side in the moving direction D of the sealing member 19, thereby enabling reliable opening.

(開封に関係する固定部の距離関係)
図22、図23に示すように第一の接合部22bを確実に剥がすためには第一の接合部22bと固定部18cの間には次のような長さの関係が求められる。まず開封部材20と、開口部35aと、固定部18cと、を通り、開封部材20の回転軸に垂直な平面を見た時に、第一の接合部22aの中で最後にはがされる点を第一の点22dとする。第一の点22dは、第一の接合部22aのなかで開口部に近い側の端部の点である。そして固定部18cから現像剤袋16に沿って第一の点22dとの距離をM1とする。そして開口部35aを含む方向に、固定部18dから第一の点22dまで現像剤収納袋16の沿って測った距離をM2とする。なお開口部35aは現像剤袋16の素材が存在しない空間であるが、この開口部16の幅も距離に含める。
(Distance relation of fixed part related to opening)
As shown in FIGS. 22 and 23, the following length relationship is required between the first joint portion 22b and the fixing portion 18c in order to reliably peel off the first joint portion 22b. First, when the flat surface perpendicular to the rotation axis of the opening member 20 is viewed through the opening member 20, the opening 35a, and the fixing portion 18c, the last is peeled off in the first joint portion 22a. Is the first point 22d. The first point 22d is a point at an end portion closer to the opening in the first joint portion 22a. The distance between the fixed portion 18c and the first point 22d along the developer bag 16 is M1. The distance measured along the developer storage bag 16 from the fixed portion 18d to the first point 22d in the direction including the opening 35a is M2. The opening 35a is a space where the material of the developer bag 16 does not exist, but the width of the opening 16 is also included in the distance.

この時M1<M2を満たすようにして第一の接合部を剥がせるようにしている。
ここで上記M1<M2の関係について詳細に述べる。
At this time, the first joint is peeled off so as to satisfy M1 <M2.
Here, the relationship of M1 <M2 will be described in detail.

(M1<M2の場合)
まずM1<M2を満たす場合は図22に示す様に第一の接合部22aに開封部材20の封止部材19を引っ張る力(矢印D)と固定部18cの踏ん張る力(矢印H)が第一の接合部22aにかかり第一の接合部22aに対して傾斜剥離とすることができる。傾斜剥離とすることで剥離力を低く設定することができる。ここで図22(a)は開封前、図22(b)は第一の接合部22aが開封する直前である。
(When M1 <M2)
First, when M1 <M2 is satisfied, as shown in FIG. 22, the first pulling force (arrow D) for pulling the sealing member 19 of the unsealing member 20 to the first joining portion 22a and the pulling force (arrow H) for the fixing portion 18c are first. It can be inclined peeling with respect to the first joint portion 22a. By adopting inclined peeling, the peeling force can be set low. Here, FIG. 22 (a) is before opening, and FIG. 22 (b) is immediately before the first joint 22a is opened.

(M1>M2の場合)
一方M1>M2の場合は図23に示す様に第一の接合部22aに開封部材20の引っ張る力がかからず第二の接合部22bに力がかかる。この場合第一の接合部22aには力がかからない為剥離しない。この場合第二の接合部22bに開封部材20からの力(矢印D)と固定部18cの踏ん張る力(矢印H)がかかる。この状態では第二の接合部22bには開封部材20の封止部材19を引っ張る力(矢印D)と固定部18cの踏ん張る力(矢印H)がかかり第二の接合部22bの部分には剥離関係がせん断剥離の関係となるため第二の接合部22bを開封することが困難である。これはせん断剥離が傾斜剥離に比べ大きな力が必要であるからである。
(When M1> M2)
On the other hand, when M1> M2, as shown in FIG. 23, the pulling force of the unsealing member 20 is not applied to the first joint portion 22a, and a force is applied to the second joint portion 22b. In this case, no force is applied to the first joint portion 22a, so that the first joint portion 22a does not peel off. In this case, the force (arrow D) from the unsealing member 20 and the force (arrow H) to stretch the fixing portion 18c are applied to the second joint portion 22b. In this state, a force (arrow D) for pulling the sealing member 19 of the unsealing member 20 and a force (arrow H) for stretching the fixing portion 18c are applied to the second joint portion 22b, and the second joint portion 22b is peeled off. Since the relationship is a relationship of shear peeling, it is difficult to open the second bonding portion 22b. This is because shear peeling requires a larger force than inclined peeling.

ここで図23(a)は開封前、図23(b)は開封部材20が回転し接合部(この場合は第二の接合部)に開封部材20により封止部材19が引っ張られる力(矢印D)かがかかる時の図である。また第二の接合部22bには力が加わるがせん断剥離の関係で力がかかるため傾斜剥離の場合に比べて非常に大きな力が必要となり剥離力を低減させる事が難しくなる。   Here, FIG. 23 (a) shows the state before opening, and FIG. 23 (b) shows the force (arrow) by which the opening member 20 rotates and the sealing member 19 is pulled by the opening member 20 to the joint (in this case, the second joint). D) It is a figure when it takes. In addition, a force is applied to the second bonding portion 22b, but a force is applied due to the shear peeling, so that a very large force is required as compared with the case of the inclined peeling, and it is difficult to reduce the peeling force.

(ヒダのある場合の距離)
なおここで前述のM1、M2の距離の測りかたの定義について述べる。M1、M2の距離は開封時に引っ張られた時の距離が重要なのでありM1、M2経路の途中にヒダ16tが無い場合は図22、図23のように展開した距離を測れば良い。また図24で示すようにM1、M2の経路の途中に製造上貼り合わせでできるヒダ16tがある場合は、開封時に引っ張った場合でもヒダ16tは伸びない(剥がれない)為ヒダ16tの部分はM1、M2の距離には含まれない。つまりヒダ16tのように力の伝達に影響しない部分は為M1やM2距離に含めない。
(Distance with folds)
Here, the definition of how to measure the distances M1 and M2 described above will be described. The distance between M1 and M2 is the distance when pulled when opening, and when there is no fold 16t in the middle of the M1 and M2 paths, the distance developed as shown in FIGS. 22 and 23 may be measured. Also, as shown in FIG. 24, if there is a crease 16t that can be bonded together in the middle of the path of M1 and M2, the crease 16t does not stretch (does not peel) even when pulled at the time of opening. , M2 is not included in the distance. That is, a portion that does not affect force transmission, such as the fold 16t, is not included in the M1 or M2 distance.

以上のようにM1<M2の関係として第一の接合部22aが第二の接合部22bより先に開封される。第一の接合部22aが第二の接合部22bより先に開封されることで第一の接合部22aが封止部材19の返し部19dができる。この返し部19dによりせん断剥離にならず傾斜剥離となる。これにより確実に現像剤袋16から封止部材19を確実に剥離できて開封可能な現像装置38を提供できる。   As described above, the first joint portion 22a is opened prior to the second joint portion 22b as M1 <M2. The first joint portion 22a is opened before the second joint portion 22b, so that the first joint portion 22a can be a return portion 19d of the sealing member 19. This return portion 19d does not cause shear peeling but inclined peeling. As a result, it is possible to provide the developing device 38 that can surely peel the sealing member 19 from the developer bag 16 and can be opened.

(固定部が複数の場合)
ここで複数の固定部と開封の関係について図31を用いて述べる。図31(a)の状態から開封部材20が回転して第一の接合部22aが開封する直前が図31(b)である。本実施例では第一の固定部18aと第二の固定部18bを有している。ここで開口部35aを挟んで最初に開封される第一の接合部22aに近い場所に配置されている第一の固定部18aの方に開封時の力が加わる。そのため前述のM1、M2の距離の測りかたに第二の固定部18bは考慮しなくてよい。このように複数の固定部がある場合には開封時の力が加わる開口部35aを挟んで最初に開封される第一の接合部22aに近い場所に配置されている固定部を基準とすればよい。
(When there are multiple fixed parts)
Here, the relationship between a plurality of fixing portions and opening is described with reference to FIG. FIG. 31B shows a state immediately before the opening member 20 is rotated from the state of FIG. In the present embodiment, the first fixing portion 18a and the second fixing portion 18b are provided. Here, a force at the time of opening is applied to the first fixed portion 18a disposed near the first joint portion 22a that is opened first with the opening 35a interposed therebetween. Therefore, the second fixing portion 18b need not be considered in measuring the distance between M1 and M2. When there are a plurality of fixing parts in this way, the fixing part arranged near the first joint part 22a that is first opened across the opening 35a to which a force at the time of opening is applied is used as a reference. Good.

(第二の接合部の位置関係)
次に第一の接合部22aの開封直前の状態を示す図12を用いて第二の接合部22bが開封部材20に巻き込まれずにより良好に開封できる配置について述べる。まず第一の接合部22aの開口部35aから遠い側の端部を第二の点22eとする。第二の接合部22bの開口部35aから遠い側の端部を第三の点22fとする。ここで第二の点22eから第三の点22fの距離をL1とする。また第二の点22eから力点部20aの距離をL2とする。この時に前記距離L1と前記距離L2の関係はL1<L2の関係が必要である。
(Position relationship of the second joint)
Next, with reference to FIG. 12 showing a state immediately before the opening of the first joint portion 22a, an arrangement in which the second joint portion 22b can be opened more favorably without being caught in the opening member 20 will be described. First, the end of the first joint 22a far from the opening 35a is defined as a second point 22e. An end of the second joint 22b far from the opening 35a is defined as a third point 22f. Here, the distance from the second point 22e to the third point 22f is L1. The distance from the second point 22e to the force point portion 20a is L2. At this time, the relationship between the distance L1 and the distance L2 needs to be L1 <L2.

その理由はL1がL2より大きい場合は第二の接合部22bの剥離が終わる前に第二の接合部22bが力点部20aに到達してしまい、第二の接合部22bが開封部材20に巻きついてしまう。第二の接合部22bに対して剥離するように力をかける事ができない。そのため現像剤袋16から封止部材19を開封困難となるのである。   The reason is that when L1 is larger than L2, the second joint 22b reaches the power point 20a before the second joint 22b is peeled off, and the second joint 22b is wound around the opening member 20. I'll follow you. A force cannot be applied to the second joint 22b so as to peel off. This makes it difficult to open the sealing member 19 from the developer bag 16.

以上のように前記距離L1と前記距離L2の関係はL1<L2とすることで封止部材19を開封部材20に巻き込まれず良好に開封可能となるのである。   As described above, when the relationship between the distance L1 and the distance L2 is L1 <L2, the sealing member 19 can be satisfactorily opened without being caught in the opening member 20.

(開口部を定義する連結部の役割)
ここで現像剤袋16の開封動作において、大きな役割を果たしている開口部を定義する連結部35bの概要を述べる。
(Role of the connecting part that defines the opening)
Here, an outline of the connecting portion 35b that defines the opening that plays a major role in the opening operation of the developer bag 16 will be described.

図11は、最初に開封する第一の接合部22aの部分の剥離を終えて、開口部35aが露出した時の図であり、第二の接合部22bの剥離を終えていない状態である。前述したとおり排出部35は開口部35aの露出が進行する開封方向Eに対して垂直方向Fにずれて複数の開口部35aを有している。そのため複数の開口部を定義する連結部35bもFの方向に複数配されることになる。これにより複数の連結部35bは、排出部35の開封が進行する方向Eの方向において、第一の接合部22aと第二の接合部22bとを橋渡ししていることになる。そのため、第一の接合部22aの開封を終えた図8の状態の時に、第二の接合部22aが開封する時の力は前記連結部35bを介して第一の固定部16dで受けることが可能となり封止部材19を現像剤袋16から剥す力を伝えることができる。つまり第二の接合部22bに矢印Dと矢印Eの方向に力がかかり第二の接合部22bも剥離可能となるのである。   FIG. 11 is a view when the peeling of the first bonding portion 22a to be opened first is completed and the opening 35a is exposed, and the peeling of the second bonding portion 22b is not completed. As described above, the discharge portion 35 has a plurality of openings 35a that are shifted in the direction F perpendicular to the opening direction E in which the exposure of the openings 35a proceeds. Therefore, a plurality of connecting portions 35b defining a plurality of openings are also arranged in the F direction. Thereby, the some connection part 35b bridges the 1st junction part 22a and the 2nd junction part 22b in the direction of the direction E in which opening of the discharge part 35 advances. Therefore, when the opening of the first joint portion 22a is finished, the force when the second joint portion 22a is unsealed is received by the first fixing portion 16d via the connecting portion 35b. Thus, the force for peeling the sealing member 19 from the developer bag 16 can be transmitted. That is, a force is applied to the second joint portion 22b in the directions of arrows D and E, and the second joint portion 22b can be peeled off.

以上のように図28(b)のように開封方向Eに対して垂直な方向Fに開口部が並んだ場合以外にも同様の効果を得られる。図28(c)のように開封方向Eに対して垂直な方向に完全に並んでいなくても連結部35bは封止部材19を現像剤袋16から剥す力を第二の接合部22bに矢印Pのように伝えることができる。また図28(d)のように開封方向Eに対して開口部35aが重なっていても連結部35bは斜めに封止部材19を現像剤袋16から剥す力を第二の接合部22bに矢印Pのように伝えることができる。即ち、複数の開口部35aが開封方向Eに垂直な方向Fにずれて配置されていればよい。   As described above, the same effect can be obtained even when the openings are arranged in the direction F perpendicular to the opening direction E as shown in FIG. Even if they are not completely aligned in the direction perpendicular to the opening direction E as shown in FIG. 28 (c), the connecting portion 35b applies the force to peel off the sealing member 19 from the developer bag 16 to the second joining portion 22b. You can tell it like the arrow P. Further, as shown in FIG. 28 (d), even if the opening 35a overlaps with the opening direction E, the connecting portion 35b applies an arrow to the second joining portion 22b to force the connection member 35b to peel the sealing member 19 off the developer bag 16. You can tell like P. That is, it is only necessary that the plurality of openings 35a are arranged so as to be shifted in the direction F perpendicular to the opening direction E.

また図28(b)のように連結部35bを含む開口部35aの周囲の部分を接合部22としても良い。この場合でも連結部35bがあることで接合部22がはがれる最後まで力をつたえることができるので開封が確実に行われる。   Further, as shown in FIG. 28B, a portion around the opening 35 a including the connecting portion 35 b may be used as the joint portion 22. Even in this case, the presence of the connecting portion 35b allows the force to be applied to the end when the joining portion 22 is peeled off, so that the unsealing is reliably performed.

また、開封部材20の回転軸と開口部35aとの関係で言えば、開口部35aは開封部材20の回転軸の方向Rにずれて配置されていると言える。このようにすることで、開封部材20の回転軸と垂直方向(矢印E)に橋渡しする連結部35bを有する。開口部35aの配置は、開封部材の回転軸方向Rにずれていれば良い。図28(b)に示すように開口部35aが回転軸方向Rに重なっていても、図28(d)に示すように回転軸方向Rに完全に重なっていなくても矢印Pのように力を伝える事が出来て連結部35bの効果がある。   In addition, in terms of the relationship between the rotation axis of the opening member 20 and the opening 35a, it can be said that the opening 35a is displaced in the direction R of the rotation axis of the opening member 20. By doing in this way, it has the connection part 35b bridged in the orthogonal | vertical direction (arrow E) with the rotating shaft of the opening member 20. As shown in FIG. The arrangement of the opening 35a may be shifted in the rotation axis direction R of the opening member. Even if the opening 35a overlaps the rotation axis direction R as shown in FIG. 28 (b), even if it does not completely overlap in the rotation axis direction R as shown in FIG. Can be transmitted and there is an effect of the connecting portion 35b.

このように現像剤を収納した現像剤収納容器26と開封部材を有した現像剤収納容器30は排出部35に橋渡しする連結部35bがあることにより開封部材20の開封力を第二の接合部22bを開封するまで伝えることができて確実に開封することができる。   In this way, the developer storage container 26 containing the developer and the developer storage container 30 having the opening member have the connecting portion 35b that bridges the discharge portion 35, so that the opening force of the opening member 20 is increased to the second joint portion. 22b can be transmitted until it is opened, and can be surely opened.

また、開口部35aと、封止部材の被係合部19bとの関係を説明する(図3)。被係合部19bは、複数の開口部35aが並んでいる方向と略垂直方向の封止部材19の一端側に設けられている。   Moreover, the relationship between the opening part 35a and the to-be-engaged part 19b of a sealing member is demonstrated (FIG. 3). The engaged portion 19b is provided on one end side of the sealing member 19 in a direction substantially perpendicular to the direction in which the plurality of openings 35a are arranged.

また、開口部35aと、開封部材20との関係を説明する(図3)。開封部材20は、複数の開口部35aが並んでいる方向と略垂直方向の封止部材19の一端側に設けられている。   Moreover, the relationship between the opening part 35a and the opening member 20 is demonstrated (FIG. 3). The opening member 20 is provided on one end side of the sealing member 19 in a direction substantially perpendicular to the direction in which the plurality of openings 35a are arranged.

このような構成でも、連結部35bにより開封部材20の開封力を第二の接合部22bを開封するまで伝えることができる効果をえることができる。   Even in such a configuration, it is possible to obtain an effect that the opening force of the opening member 20 can be transmitted until the second bonding portion 22b is opened by the connecting portion 35b.

(連結部が別部材の例)
また図21に示すように排出部35開口部35aを定義する連結部35bを別の部材(連結部材16f)としても良い。この場合開封方向Eに垂直な方向Fに長い一つの開口部16aを設け前記長い一つの開口部16aに開封方向Eに沿って橋渡しする別部材である連結部材16fを設ける構成である。この時長い一つの開口部16aの第一の接合部22a側と第二の接合部22b側にそれぞれ連結部材16fを接着、溶着等で接合されている。
(Example where the connecting part is a separate member)
Further, as shown in FIG. 21, the connecting portion 35b defining the opening 35a of the discharge portion 35 may be another member (connecting member 16f). In this case, one long opening 16a is provided in the direction F perpendicular to the opening direction E, and a connecting member 16f, which is another member that bridges along the opening direction E, is provided in the long one opening 16a. At this time, the connecting member 16f is joined to the first joint portion 22a side and the second joint portion 22b side of the one long opening portion 16a by bonding, welding, or the like.

なお現像剤袋16に連結部材16fを設けた場合においても封止部材19は前述のように接合部22と被係合部19bの間で折り返されていることで開封部材20に封止部材19を巻きつける事で開封可能としている。このような構成をとる事により複数の開口部35aを設けた場合の開口部を定義する連結部35bと連結部材16fは同じ役割を果たす。つまり長い一つの開口部16aは連結部材16fにより複数の開口部35aがある場合と同じなのである。   Even when the connecting member 16f is provided in the developer bag 16, the sealing member 19 is folded back between the joint portion 22 and the engaged portion 19b as described above, so that the sealing member 19 is attached to the opening member 20. It can be opened by wrapping. By adopting such a configuration, the connecting portion 35b and the connecting member 16f that define the opening when a plurality of openings 35a are provided play the same role. That is, one long opening 16a is the same as the case where there are a plurality of openings 35a by the connecting member 16f.

よって第一の接合部22aの開封を終えて第二の接合部22bを剥離する時に、開封部材20が第二の接合部22aが開封する時の力(矢印D)は前記連結部材16fを介して第一の固定部16dで矢印Hに受けることが可能となる。よって、封止部材19を現像剤袋16から剥す力を伝えることができる。つまり第二の接合部22bに矢印Dと矢印Hの方向に力がかかり第二の接合部22bも可能となるのである。   Therefore, when the opening of the first joint portion 22a is finished and the second joint portion 22b is peeled off, the force (arrow D) when the unsealing member 20 opens the second joint portion 22a is passed through the connecting member 16f. The first fixing portion 16d can receive the arrow H. Therefore, it is possible to transmit the force for peeling the sealing member 19 from the developer bag 16. That is, a force is applied to the second joint portion 22b in the directions of arrows D and H, and the second joint portion 22b is also possible.

このように長い一つの開口部16aは連結部材16fにより複数の開口部35aをつくることで連結部材16fのみを強くしたりすることも可能となる。   In this way, it is possible to strengthen only the connecting member 16f by forming a plurality of openings 35a with the connecting member 16f.

(連結部が無い場合の開封性の課題)
ここで本発明を適用せず現像剤袋16が開封困難な例について述べる。これは図13、14で示すように連結部35bが存在せず開封が困難になる場合である。図13は連結部35bが存在せず開口部16aが一つの例であり、図13(a)は第二の接合部22bの剥離前の状態で、図13(b)と図15は第二の接合部を剥離する時の状態を示した図である。また図8は本実施例における第二の接合部22aを引き剥がす状態の開口部35a周辺の拡大断面図であり、図14は連結部35bが存在せず開封が困難になる場合の開口部35a周囲の断面図である。
(Problems of unsealing when there is no connecting part)
Here, an example in which the developer bag 16 is difficult to open without applying the present invention will be described. In this case, as shown in FIGS. 13 and 14, the connecting portion 35b does not exist and it is difficult to open. FIG. 13 shows an example in which the connecting portion 35b does not exist and the opening portion 16a is an example. FIG. 13 (a) shows a state before the second joining portion 22b is peeled off, and FIG. 13 (b) and FIG. It is the figure which showed the state when peeling the junction part of. FIG. 8 is an enlarged cross-sectional view of the periphery of the opening 35a in the state where the second joint 22a is peeled off in this embodiment, and FIG. 14 shows the opening 35a when the connecting portion 35b does not exist and it is difficult to open the opening 35a. FIG.

この場合第二の接合部22bまで開封が進んだ状態が図14(a)であり、この状態から更に開封部材20の回転により封止部材19が矢印Dの方向に引っ張られ移動する。すると連結部35bを有さない為に、第一の固定部16dからの力を、開口部16aの中央の第二の接合部22b側に伝達することができない。そのため図14(b)、図13(b)のように第二の接合部22bは枠体の固定部18aからの拘束力がなくなり開口部16aが矢印Dの方向に大きく開いていく。更に第二の接合部22bが封止部材19に引っ張られて図14(c)に示す様に開口部16aが変形する。この場合第二の接合部22bに働く力は図8に示すような傾斜剥離の位置関係にならず、図14(b)に示すように開口部35aが変形する事でせん断剥離(略0°剥離)となるため剥離するために大きな力が必要となる。しかも第一の固定部16dが支持する力を第二の接合部22bに伝達できないため第二の接合部22bは剥離できないまま開封部材20に引っ張られていく。そのため第二の接合部22bの長手中央付近の開口部16aが更に大きく開いてしまい、開封部材20に巻きついてしまう。   In this case, FIG. 14A shows a state in which the opening has advanced to the second joint portion 22b, and the sealing member 19 is further pulled and moved in the direction of arrow D by the rotation of the opening member 20 from this state. Then, since it does not have the connection part 35b, the force from the 1st fixing | fixed part 16d cannot be transmitted to the 2nd junction part 22b side of the center of the opening part 16a. Therefore, as shown in FIG. 14B and FIG. 13B, the second joining portion 22b has no restraining force from the fixing portion 18a of the frame body, and the opening portion 16a opens greatly in the direction of the arrow D. Further, the second joint 22b is pulled by the sealing member 19, and the opening 16a is deformed as shown in FIG. In this case, the force acting on the second bonding portion 22b does not have the positional relationship of inclined peeling as shown in FIG. 8, but shear peeling (approximately 0 °) is caused by the deformation of the opening 35a as shown in FIG. Therefore, a large force is required for peeling. And since the force which the 1st fixing | fixed part 16d supports cannot be transmitted to the 2nd junction part 22b, the 2nd junction part 22b is pulled by the opening member 20 without being able to peel. Therefore, the opening 16a near the longitudinal center of the second joint portion 22b is further widened and is wound around the opening member 20.

なお現像剤を収納するものが構造体のように硬いものであればこのような変形は無く従来例のように開封可能である。しかし、現像剤を変形可能な柔らかい袋状のものに収納し、開口部が開封時変形するようなものを開封する構成の場合は前述のように連結部35bがないと開封が難しくなる。   If the developer is stored as hard as a structure, it can be opened as in the prior art without such deformation. However, when the developer is stored in a deformable soft bag and the opening is deformed when the opening is opened, the opening is difficult without the connecting portion 35b as described above.

以上述べてきたように画像形成装置Bの開封部材20に駆動力を伝える事で封止部材19(=トナーシール)を開封可能とし、ユーザーがトナーシールを引き取り去る必要がなくなり、より簡便に現像装置38、プロセスカートリッジAを交換して使用できる。また開封後の封止部材19が開封部材20に固定されていることで、プロセスカートリッジAから廃材を出すことなく開封ができる。   As described above, the driving force is transmitted to the opening member 20 of the image forming apparatus B, so that the sealing member 19 (= toner seal) can be opened, and the user does not need to remove the toner seal, and development is simpler. The apparatus 38 and the process cartridge A can be exchanged for use. Further, since the sealing member 19 after being opened is fixed to the opening member 20, the opening can be performed without taking out the waste material from the process cartridge A.

<押圧部材と現像剤排出概要について>
(押圧部材)
図16に示すように押圧部材21は軸部21aと、軸部21aに固定された押圧シート21bを備えており、第一の枠体17と第二の枠体18の内部に回転可能に設けられている。
<About pressing member and developer discharge outline>
(Pressing member)
As shown in FIG. 16, the pressing member 21 includes a shaft portion 21a and a pressing sheet 21b fixed to the shaft portion 21a, and is provided rotatably inside the first frame body 17 and the second frame body 18. It has been.

まず軸部21aは開封部材20と同一部品で機能させている(21a=20)。よって前述のように不図示の画像形成装置B本体からの駆動手段により駆動力が伝達され矢印Cの方向に押圧部材21(=20)が回転する。   First, the shaft portion 21a functions as the same component as the opening member 20 (21a = 20). Therefore, as described above, the driving force is transmitted by the driving means from the image forming apparatus B main body (not shown), and the pressing member 21 (= 20) rotates in the direction of the arrow C.

次に押圧シート21bは断面が四角い軸部21aの一面に固定されて、軸部材21aと共に回転する。なお前記押圧シート21bの材質としてはPET、PPS(ポリフェニレンスルファイド)、ポリカーボネイト、等の可撓性シートで、厚みは0.05〜0.1mm程度を用い、その先端は軸部21aの外接円より外側に突出している。ここで本実施例では軸部21aの異なる面に封止部材19と押圧シート21bを固定しているが、軸部21aの同じ面に封止部材19と押圧シート21bを固定しても良い。   Next, the pressing sheet 21b is fixed to one surface of the shaft portion 21a having a square cross section, and rotates together with the shaft member 21a. The material of the pressing sheet 21b is a flexible sheet such as PET, PPS (polyphenylene sulfide), polycarbonate, etc., with a thickness of about 0.05 to 0.1 mm, and its tip is a circumscribed circle of the shaft portion 21a. It protrudes more outward. Here, in this embodiment, the sealing member 19 and the pressing sheet 21b are fixed to different surfaces of the shaft portion 21a. However, the sealing member 19 and the pressing sheet 21b may be fixed to the same surface of the shaft portion 21a.

また図16、図17に示すように前記押圧シート21bは現像剤を攪拌し、現像ローラ13や現像剤供給23の方へ搬送する機能も兼ねている。   Further, as shown in FIGS. 16 and 17, the pressing sheet 21 b also has a function of stirring the developer and transporting it toward the developing roller 13 and the developer supply 23.

<現像剤収納袋からの現像剤排出概要>
(開封前から開封時の排出概要)
まず開封前から開封開始時の現像剤の排出に関して前述の図7、図8に示すように封止部材19は力点部20aの方へ引っ張り(矢印D)、現像剤袋16は枠体の固定部18cで支えられる。そのため、開封時は力点部20aと、枠体の固定部18cと、接合部22の剥離する場所との3か所は、開封部材20の回転軸に垂直な断面において直線状に並ぶ方向に移動する。このように開封部材20が封止部材19に力を与え開封動作を行う前の時と、開封動作を開始し前記第一の接合部22aでの接合が開封される時とで、開口部35aの位置が変化することにより開口部35a近傍の現像剤滞留を防ぐことができて排出性が良い。
<Outline of developer discharge from developer storage bag>
(Outline of discharge before opening from before opening)
First, as shown in FIGS. 7 and 8, the discharge of the developer at the start of opening from before opening, the sealing member 19 is pulled toward the power point portion 20a (arrow D), and the developer bag 16 is fixed to the frame. It is supported by the portion 18c. Therefore, at the time of opening, the three points of the force point part 20a, the frame fixing part 18c, and the place where the joint part 22 peels move in a direction aligned in a straight line in the cross section perpendicular to the rotation axis of the opening member 20. To do. Thus, when the opening member 20 does not apply force to the sealing member 19 and performs the opening operation, and when the opening operation is started and the bonding at the first bonding portion 22a is opened, the opening portion 35a is opened. As a result of the change in position, the developer staying in the vicinity of the opening 35a can be prevented, and the discharge performance is good.

(開封後の排出概要 押圧時)
また開封後は図8(b)に示すように前述の現像剤袋16から封止部材19を開封すると、まず開口部35aは現像剤袋16の下方に開くように配置してあるため、重力の作用と開封時の現像剤袋16の振動等により開口部35a付近の現像剤が排出される。
(Outline of discharge after opening)
Further, after opening, when the sealing member 19 is opened from the developer bag 16 as shown in FIG. 8B, the opening 35a is first arranged to open below the developer bag 16. The developer in the vicinity of the opening 35a is discharged by the action of the above and the vibration of the developer bag 16 at the time of opening.

開封後更に開封部材20の回転が進むと、開封部材20に固定された現像剤袋16を押す押圧シート21bも回転し、図9で示すように現像剤袋16により開封部材20に巻き着く。ここで図16に示すように押圧シート21bは弾性を有しているため、もとの形状に回復しようとするために現像剤袋16を矢印J方向に押す。この時現像剤袋16は押圧シート21bにより押され収納するトナーを介して第二の枠体18に押さえつけられ現像剤袋16全体が変形する。また現像剤袋16は押圧シート21bにより押され内容積が少なくなる。このように現像剤袋16の容積減と全体形状の変化により、現像剤袋16の内部の現像剤は撹拌され、それにより開口部35aから現像剤が排出されやすくなる。またこの時現像剤袋16は開口部35a以外は閉じており開口部35a以外に現像剤の逃げ道が無いため開口部35aからの排出性が高い。以上のような排出作用により矢印Iの方向に現像剤を排出しやすい。   When the opening member 20 further rotates after opening, the pressing sheet 21b that pushes the developer bag 16 fixed to the opening member 20 also rotates, and is wound around the opening member 20 by the developer bag 16 as shown in FIG. Here, as shown in FIG. 16, since the pressing sheet 21b has elasticity, the developer bag 16 is pushed in the direction of the arrow J in order to restore the original shape. At this time, the developer bag 16 is pressed against the second frame 18 through the toner stored by being pressed by the pressing sheet 21b, and the entire developer bag 16 is deformed. Further, the developer bag 16 is pressed by the pressing sheet 21b and the internal volume is reduced. Thus, the developer in the developer bag 16 is agitated by the volume reduction of the developer bag 16 and the change in the overall shape, and the developer is easily discharged from the opening 35a. At this time, the developer bag 16 is closed except for the opening 35a, and there is no escape path for the developer other than the opening 35a, so that the discharge from the opening 35a is high. Due to the discharging action as described above, the developer is easily discharged in the direction of arrow I.

なおこの時現像剤袋16は少なくとも一部が第二の枠体18に当接して押さえつけられれば現像剤袋16は変形できる。   At this time, the developer bag 16 can be deformed if at least a part of the developer bag 16 is pressed against the second frame 18.

また現像ローラ13の回転軸方向と複数の開口部35aの並ぶ方向Fを揃えることで、現像剤を排出時に現像ローラ13の長手方向全体に現像剤が偏りなく供給され易くすることができる。   Further, by aligning the rotation axis direction of the developing roller 13 and the direction F in which the plurality of openings 35a are arranged, it is possible to easily supply the developer to the entire longitudinal direction of the developing roller 13 without discharging the developer.

また現像装置38が画像形成装置Bに装着された際に、開口部35aが重力方向に開くように設けられることで現像剤の排出性を向上させる事ができる。   Further, when the developing device 38 is attached to the image forming apparatus B, the developer discharge performance can be improved by providing the opening 35a so as to open in the direction of gravity.

また枠体(17、18)内部に設けられて押圧部材21が現像剤袋16を第二の枠体18に押し付けるように押圧することで現像剤の排出性を向上させる事が出来る。   Further, the developer discharging performance can be improved by pressing the developer bag 16 against the second frame 18 provided in the frame (17, 18).

また、封止部材19も、基材がポリエチレンテレフタレート(PET)、ポリエチレン、ポリプロピレン等で、厚み0.03〜0.15mmの可撓性シートを用いている為、上記押圧シート21bと同様のメカニズムによって排出作用に関わっている。   Further, since the sealing member 19 is made of polyethylene terephthalate (PET), polyethylene, polypropylene or the like and uses a flexible sheet having a thickness of 0.03 to 0.15 mm, the same mechanism as that of the pressing sheet 21b is used. It is related to the discharge action.

(排出概要 現像剤袋形状回復)
そして図17で示すように更に開封部材20の回転が進み押圧シート21bが現像剤袋16から離れる。この時現像剤袋16は可撓性を有しているため収納する現像剤の重さで押圧される前の状態に回復しようとする(矢印K)。そしてまた押圧シート21bも回転し、図16で示すように現像剤袋16を第二の枠体18に押し現像剤袋16が変形することで開口部35a付近以外の現像剤も動かされ開口部35aより排出される。
(Outline of the recovery of the developer bag shape)
Then, as shown in FIG. 17, the rotation of the unsealing member 20 further advances and the pressing sheet 21 b is separated from the developer bag 16. At this time, since the developer bag 16 has flexibility, the developer bag 16 tries to recover to the state before being pressed by the weight of the developer stored (arrow K). Further, the pressing sheet 21b also rotates, and as shown in FIG. 16, the developer bag 16 is pushed to the second frame 18, and the developer bag 16 is deformed, so that the developer other than the vicinity of the opening 35a is also moved. It is discharged from 35a.

(排出概要 押圧/回復の繰り返し)
開封直後の現像剤が現像剤袋16内部に多くある場合は押圧シート21bおよび開封部材20の現像剤袋16への侵入量が繰り返し変化し、第二の枠体18に押しつけるように現像剤袋16を変形させる。この押圧部材21の押圧による現像剤袋16の収縮と、現像剤袋16内部の現像剤の重さと現像剤袋16可撓性による回復を繰り返す。また前記作用により現像剤袋16自体が動くため現像剤袋16が振動し、この振動によっても現像剤袋16内部の現像剤が開口部35aから排出される。また押圧部材21は回転するため繰り返し現像剤袋16を押圧させることができる。
(Summary of discharge, repeated pressing / recovery)
When there is a lot of developer immediately after opening in the developer bag 16, the amount of intrusion of the pressing sheet 21 b and the opening member 20 into the developer bag 16 is repeatedly changed, and the developer bag is pressed against the second frame 18. 16 is deformed. The contraction of the developer bag 16 due to the pressing of the pressing member 21 and the recovery due to the weight of the developer in the developer bag 16 and the flexibility of the developer bag 16 are repeated. Further, because the developer bag 16 itself moves due to the above action, the developer bag 16 vibrates, and the developer inside the developer bag 16 is also discharged from the opening 35a by this vibration. Further, since the pressing member 21 rotates, the developer bag 16 can be repeatedly pressed.

(現像剤袋を枠体に貼りつけた例)
なお現像剤袋16が第二の枠体18へ押圧される部分27は図25に示す様に接着剤、両面テープ等の接合部28を設けて接合されている場合でも押圧シート21bが現像剤袋16を押圧し現像剤を排出することができる。
(Example of attaching the developer bag to the frame)
Even when the portion 27 where the developer bag 16 is pressed against the second frame 18 is bonded with a bonding portion 28 such as an adhesive or a double-sided tape as shown in FIG. 25, the pressing sheet 21b is the developer. The developer can be discharged by pressing the bag 16.

(現像剤が少なくなった場合)
画像形成を行い現像剤袋16内の現像剤が少なくなった場合について図32を用いて説明する。尚、簡略化の為に押圧部材21を中心に説明するが、封止部材19に関しても同様の現象となる。開封直後は図32(a)に示すように収納する現像剤の重みにより現像剤袋16は押圧部材21に常に接触するように形状が追従して大きさ(内容積)を周期的に変化させる。しかし収納する現像剤が少なくなると図32(b)に示すように現像剤の重さが軽くなり押圧部材21に追従しなくなり周期定期に離接を繰り返すようになる。現像剤袋16と押圧部材21が周期的に接触するので、現像剤袋16が振動する事による現像剤の排出が可能である。
(When developer is low)
The case where the image forming is performed and the developer in the developer bag 16 is reduced will be described with reference to FIG. In addition, although it demonstrates centering on the press member 21 for simplification, it becomes the same phenomenon also regarding the sealing member 19. FIG. Immediately after opening, the developer bag 16 changes its size (internal volume) periodically so that the developer bag 16 always contacts the pressing member 21 due to the weight of the developer stored as shown in FIG. . However, when the amount of developer to be stored decreases, as shown in FIG. 32 (b), the weight of the developer becomes lighter and does not follow the pressing member 21, and the contact and separation are repeated periodically. Since the developer bag 16 and the pressing member 21 periodically come into contact with each other, the developer can be discharged by the vibration of the developer bag 16.

現像剤袋16と押圧部材21の位置関係によっては、現像剤が少なくなった時点で、現像剤袋16と押圧部材21が常に接触しなくなってしまう場合が有る。即ち、周期的な接触による現像剤の排出も行われなくなってしまう為、現像剤袋16内に排出されない現像剤が残ってしまう可能性が有る。この時、図32(c)に示すように押圧部材21に押圧シート21bが固定され、押圧シート21bが常に現像剤袋16に接触するのに充分な長さを有する構成とするのがよい。このようにすることで、現像剤袋16に対して押圧シート21bが撓んだ状態で接触している為に、現像剤が少なくなり現像剤袋16が変形した場合であっても、現像剤袋16と押圧部材21が接触しないという状態にならず、排出効果を維持する事が可能である。つまり、押圧部材21に可撓性シートを用いると、現像剤袋の状態に応じて、押圧部材の回転軸中心から現像剤袋16を押圧する作用点までの距離を変化させる事が可能である。具体的には、現像剤袋16にトナーが充分入っている時は押圧シート21bが撓んだ状態で現像剤袋16を押圧しているが、現像剤袋16のトナーが少なくなるにつれて、押圧シート21bの撓みがより解消された状態で現像剤袋16と接触するようになっている。   Depending on the positional relationship between the developer bag 16 and the pressing member 21, the developer bag 16 and the pressing member 21 may not always come into contact with each other when the developer is low. That is, since the developer is not discharged due to periodic contact, the developer that is not discharged may remain in the developer bag 16. At this time, as shown in FIG. 32 (c), it is preferable that the pressing sheet 21b is fixed to the pressing member 21 and has a sufficient length so that the pressing sheet 21b always contacts the developer bag 16. By doing so, even if the developer bag 16 is deformed because the pressure sheet 21b is in contact with the developer bag 16 in a bent state, the developer bag 16 is deformed. The bag 16 and the pressing member 21 do not come into contact with each other, and the discharge effect can be maintained. That is, when a flexible sheet is used for the pressing member 21, it is possible to change the distance from the center of the rotation axis of the pressing member to the point of action for pressing the developer bag 16 according to the state of the developer bag. . Specifically, when the developer bag 16 is sufficiently filled with toner, the developer bag 16 is pressed with the pressing sheet 21b bent, but as the toner in the developer bag 16 decreases, the pressure is reduced. The developer bag 16 is brought into contact with the sheet 21b in a state in which the bending of the sheet 21b is further eliminated.

また、押圧部材21の回転軸方向において、現像剤袋16内の現像剤に偏りが生じ、現像剤袋16と押圧部材21の接触ムラが発生した場合であっても、上記押圧部材21に押圧シート21bが固定された構成であれば、上述と同様に排出効果を維持する事が可能である。   Even when the developer in the developer bag 16 is biased in the direction of the rotation axis of the pressing member 21 and uneven contact between the developer bag 16 and the pressing member 21 occurs, the pressing member 21 is pressed. If the sheet 21b is fixed, the discharge effect can be maintained as described above.

(押圧シートと封止部材の兼用)
なお押圧シート21と封止部材19を兼用させて1部品で両方の機能をもたせてもよい。これは開封封後に接合部22が現像剤袋16と離れるため、封止部材19の接合部22側の端部は自由端となる。このため封止部材19は押圧シート21bの機能を有することができる。このように押圧部材21の軸部21aの機能を開封部材20が有し、押圧シート21bの機能を封止部材19が有することが可能となる。
このようにすると、部品点数の削減ができてコストダウンが図れる。
(Combined use of pressure sheet and sealing member)
The pressing sheet 21 and the sealing member 19 may be used together to provide both functions with one component. Since the joining portion 22 is separated from the developer bag 16 after opening, the end of the sealing member 19 on the joining portion 22 side is a free end. For this reason, the sealing member 19 can have the function of the pressing sheet 21b. Thus, the opening member 20 can have the function of the shaft portion 21a of the pressing member 21, and the sealing member 19 can have the function of the pressing sheet 21b.
In this way, the number of parts can be reduced and the cost can be reduced.

以上のように現像剤排出口である開口部35aに現像剤排出ローラ等の他の排出部品を設けることなく現像剤袋16内部の現像剤を良好に排出可能とし、開口部35a付近の現像剤の凝集、ブリッジを防止できる。これにより物流、保管時等で現像剤袋16内の現像剤がタッピングにより固まった場合でもこのような現像剤袋16全体や開口部35a周囲の移動により現像剤の塊を崩すことで現像剤の排出が困難になる状態を防止できる。   As described above, the developer inside the developer bag 16 can be satisfactorily discharged without providing other discharge parts such as a developer discharge roller in the opening 35a which is a developer discharge port, and the developer near the opening 35a. Aggregation and bridging can be prevented. As a result, even when the developer in the developer bag 16 is hardened by tapping at the time of distribution or storage, the developer lump is broken by moving the developer bag 16 as a whole or around the opening 35a. It is possible to prevent a situation in which discharge becomes difficult.

(押圧部材が一部品の例)
また押圧部材21が軸部21aと押圧シート21bの別部品ではなく、図26(a)で示すように同一部品で押圧シート21bの作用をする凸部21cを押圧部材21に設けても同様に現像剤の排出を行うことができる。押圧部材21の軸部21aのみで構成される場合において、回転中心に垂直な断面で見たときに前記軸部21aの断面が多角形(図26(b))の形状やカム形状(図26(c))を有する場合でも現像剤袋16を枠体29に押圧して変形させる事が可能である。これは押圧部材21を少なくとも現像剤袋16に接するように配置すると、押圧部材21の回転中心から外形への距離が変化する為に押圧部材21の現像剤袋16への侵入量も変化するためである。つまり中心に回転軸をもつ円形断面の軸で無い限り、押圧部材21の回転により現像剤袋16を変形させる事が可能である。図26で示すように押圧部材21の中心から遠い外形までの距離21cと外形まで近い距離21dが異なっているため押圧部材21の現像剤袋16への侵入量も変化する。また図33(b)は断面が十字形の押圧部材21の断面図、図33(a)は十字形の押圧部材21を有する現像剤収納ユニット25の断面説明図である。図33に示すように押圧部材の中心から外形までの距離が等しい4本の凸部21eを有する場合、4本の凸部21eの外形(21c)は共に等しい。しかし、凸部21e以外に中心から近い外形の部分(距離21d)を有するため現像剤袋16への侵入量を変化させることができる。即ち、押圧部材21は、押圧部材21の回転中心に垂直な断面において、押圧部材21の回転中心から押圧部材の外形までの距離が異なる部分を有する回転部材とすることができる。
(Example where the pressing member is one part)
Further, the pressing member 21 is not a separate part of the shaft portion 21a and the pressing sheet 21b, and the protruding member 21c that acts as the pressing sheet 21b with the same component is provided on the pressing member 21 as shown in FIG. The developer can be discharged. In the case of only the shaft portion 21a of the pressing member 21, the shaft portion 21a has a polygonal shape (FIG. 26B) or a cam shape (FIG. 26) when viewed in a cross section perpendicular to the rotation center. Even when (c) is included, the developer bag 16 can be pressed against the frame body 29 to be deformed. This is because, when the pressing member 21 is disposed so as to be in contact with at least the developer bag 16, the distance from the rotation center of the pressing member 21 to the outer shape changes, so that the amount of the pressing member 21 entering the developer bag 16 also changes. It is. That is, the developer bag 16 can be deformed by the rotation of the pressing member 21 as long as it is not a circular cross-sectional axis having a rotation axis at the center. As shown in FIG. 26, since the distance 21c to the outer shape far from the center of the pressing member 21 and the distance 21d close to the outer shape are different, the intrusion amount of the pressing member 21 into the developer bag 16 also changes. FIG. 33B is a cross-sectional view of the cross-shaped pressing member 21 and FIG. 33A is a cross-sectional explanatory view of the developer storage unit 25 having the cross-shaped pressing member 21. As shown in FIG. 33, when there are four convex portions 21e having the same distance from the center of the pressing member to the outer shape, the outer shapes (21c) of the four convex portions 21e are the same. However, since it has an outer portion (distance 21d) close to the center other than the convex portion 21e, the amount of penetration into the developer bag 16 can be changed. That is, the pressing member 21 can be a rotating member having a portion where the distance from the rotation center of the pressing member 21 to the outer shape of the pressing member is different in a cross section perpendicular to the rotation center of the pressing member 21.

このように押圧部材21により現像剤袋16は押される事(矢印J)で枠体29に押しつけられて変形して内容積が減少し内部の現像剤が押し出されて開口部35aより排出される(矢印I)。   In this way, the developer bag 16 is pushed by the pressing member 21 (arrow J) and is pressed against the frame body 29 to be deformed, the internal volume is reduced, and the internal developer is pushed out and discharged from the opening 35a. (Arrow I).

また画像形成時の姿勢において押圧部材21の軸部21a(=20)は現像剤袋16の重力方向下方にあり現像剤袋16と接している。そして押圧部材21の軸部21a(=20)は断面形状が四角であり、断面形状が丸ではないため軸部21a(=20)の回転により現像剤袋16への軸部21a(=20)の侵入量は前述のように周期的に変化する。前記現像剤袋16への軸部21a(=20)の侵入量が変化することによっても現像剤袋16の容積を変化させ、また振動させることができて排出性が向上できる。   In the posture during image formation, the shaft portion 21 a (= 20) of the pressing member 21 is below the developer bag 16 in the gravity direction and is in contact with the developer bag 16. Since the shaft 21a (= 20) of the pressing member 21 has a square cross-sectional shape and is not round, the shaft 21a (= 20) to the developer bag 16 is rotated by the rotation of the shaft 21a (= 20). As described above, the amount of intrusion changes periodically. The volume of the developer bag 16 can also be changed and vibrated by changing the amount of penetration of the shaft portion 21a (= 20) into the developer bag 16, thereby improving the discharge performance.

さらには、押圧部材21に押圧シート21bが固定された構成あれば、現像剤袋16に対して押圧シート21bが撓んだ状態で接触している為に、現像剤袋16が変形した場合であっても、現像剤袋16と押圧部材21が接触しないという状態にならない。そのため、排出効果を維持する事が可能である。また、可撓性を有する押し圧シート21bを有する構成でなくても、凸部21cを可撓性を有するような薄いシート状にし、現像剤袋16に接触するのに充分な長さを有するようにしても上述と同様に排出効果を維持する事が可能である。   Furthermore, if the pressing sheet 21 b is fixed to the pressing member 21, the developer bag 16 is deformed because the pressing sheet 21 b is in contact with the developer bag 16 in a bent state. Even if it exists, it will not be in the state where the developer bag 16 and the pressing member 21 do not contact. Therefore, it is possible to maintain the emission effect. Further, even if the pressing sheet 21b having flexibility is not used, the convex portion 21c is formed into a thin sheet having flexibility and has a length sufficient to contact the developer bag 16. Even if it does in this way, it is possible to maintain the discharge effect similarly to the above-mentioned.

<押圧部材と現像剤袋内の現像剤循環概要>
以上、前記押圧部材21の作用効果として、トナー排出について説明したが次に前記押圧部材21の別の作用効果である現像剤袋内の現像剤循環作用について図17を用いて説明する。
<Outline of developer circulation in pressing member and developer bag>
The toner discharge has been described as the function and effect of the pressing member 21. Next, the developer circulation function in the developer bag, which is another function and effect of the pressing member 21, will be described with reference to FIG.

図17に示す様に開封部材20の回転が進み押圧シート21bが現像剤袋16から離れる。この時現像剤袋16は可撓性を有しているため収納する現像剤の重さで押圧される前の状態に回復しようとする(矢印K)。そしてまた押圧シート21bも回転し、図16で示すように現像剤袋16を第二の枠体18に押し現像剤袋16が変形することで開口部35a付近以外の現像剤も動かされる、この現像剤の動きにより現像剤袋16内での現像剤の循環作用が起きるのである。すなわち、現像剤袋16の変形作用が、現像剤袋16内の現像剤を動かすことで、現像剤袋16内の現像剤循環作用を起こすのである。また、現像剤袋の変形振幅と現像剤循環作用は比例関係にある。   As shown in FIG. 17, the rotation of the opening member 20 advances and the pressing sheet 21 b is separated from the developer bag 16. At this time, since the developer bag 16 has flexibility, the developer bag 16 tries to recover to the state before being pressed by the weight of the developer stored (arrow K). Further, the pressing sheet 21b also rotates, and the developer bag 16 is pushed to the second frame 18 as shown in FIG. 16, and the developer bag 16 is deformed to move the developer other than the vicinity of the opening 35a. The movement of the developer causes the developer to circulate in the developer bag 16. That is, the deformation action of the developer bag 16 causes the developer circulation action in the developer bag 16 by moving the developer in the developer bag 16. Further, the deformation amplitude of the developer bag and the developer circulation action are in a proportional relationship.

(真空成形)
実施例2として、実施例1の現像剤袋16の代わりに現像剤収納部材34を用いたものである。現像剤収納部材34は、シート状の素材を真空成形、圧空成形、プレス成形により形つくったものを使用したものである。開封部材を有した現像剤収納容器30は実施例1と同様に現像剤収納部材34と、封止部材19と、開封部材20と、第一の枠体17、第二の枠体18と、を有している。なお開封部材20は実施例1と同様に押圧部材21の機能と現像剤の攪拌機能とを兼ね備えた部材となっている。
(Vacuum forming)
In Example 2, a developer accommodating member 34 is used instead of the developer bag 16 of Example 1. The developer accommodating member 34 uses a sheet-shaped material formed by vacuum forming, pressure forming, or press forming. The developer storage container 30 having the opening member is similar to the developer storage member 34, the sealing member 19, the opening member 20, the first frame 17, the second frame 18, and the like. have. The opening member 20 is a member having both the function of the pressing member 21 and the function of stirring the developer, as in the first embodiment.

(現像剤袋の構成)
図18、図29(c)で示すように現像剤収納部材34の構成は真空成形、圧空成形、プレス成形により形つくられた可撓性を有する可撓性容器である成形部34aと、シート状の通気部34bから構成される。ここで成形部34aと通気部34bの接合は熱溶着、レーザー溶着、接着剤、接着テープ等がある。現像剤収納部材34に通気性をもたせる理由としては実施例1と同じで製造時、物流時および保管時に対応するためである。
(Configuration of developer bag)
As shown in FIGS. 18 and 29 (c), the developer accommodating member 34 is composed of a forming portion 34a which is a flexible container having flexibility formed by vacuum forming, pressure forming, press forming, and a sheet. It is comprised from the ventilation part 34b of a shape. Here, the bonding of the molding part 34a and the ventilation part 34b includes thermal welding, laser welding, adhesive, adhesive tape, and the like. The reason why the developer accommodating member 34 has air permeability is the same as that of the first embodiment, and corresponds to the case of manufacturing, distribution and storage.

成形部34aの素材としてABS・PMMA・PC・PP・PE・HIPS・PET・PVCなどや、これらの複合多層材料などが好ましい。また成形部34aの厚みは成形前のシート状の厚みで0.1〜1mm程度のものが好ましい。成形部34aの材料や厚みはコストや製品仕様、製造条件等により適宜選定すればよい。   ABS, PMMA, PC, PP, PE, HIPS, PET, PVC, or a composite multilayer material thereof is preferable as the material of the molding portion 34a. Moreover, the thickness of the molding part 34a is preferably about 0.1 to 1 mm as a sheet-like thickness before molding. What is necessary is just to select suitably the material and thickness of the shaping | molding part 34a according to cost, product specification, manufacturing conditions, etc.

成形部34aは、成形部34aの外周34cで通気部34bと接合されている。現像剤収納部材34は、内部に現像剤を収納している。また外周部34cの一部に現像剤収納部材34の固定部16d(被固定部)が設けられている。成形部34aの形状は枠体17、18の内側に沿った形状となっている(図19)。   The molding part 34a is joined to the ventilation part 34b at the outer periphery 34c of the molding part 34a. The developer storage member 34 stores the developer therein. Further, a fixing portion 16d (fixed portion) of the developer storage member 34 is provided in a part of the outer peripheral portion 34c. The shape of the molding part 34a is a shape along the inside of the frames 17 and 18 (FIG. 19).

そして現像剤を収納した現像剤収納容器26は現像剤収納部材34と、現像剤収納部材34の排出部35を開封可能に覆い現像剤収納部材34内部にトナーを封止している封止部材19から構成される。   The developer storage container 26 storing the developer covers the developer storage member 34 and the discharge portion 35 of the developer storage member 34 so as to be openable, and seals the toner inside the developer storage member 34. 19.

開封部材を有した現像剤収納容器30は、前記封止部材19を現像剤収納部材34から開封する開封部材20と前記現像剤を収納した現像剤収納容器26から構成される。   The developer storage container 30 having an opening member includes an opening member 20 that opens the sealing member 19 from the developer storage member 34 and a developer storage container 26 that stores the developer.

現像装置38は、開封部材を有した現像剤収納容器30と、現像手段である現像ローラ13、現像ブレード15とこれらを支持する第一の枠体17と第二の枠体18から構成される。   The developing device 38 includes a developer container 30 having an opening member, a developing roller 13 as a developing means, a developing blade 15, a first frame body 17 and a second frame body 18 that support them. .

ここで排出部35は成形部34aに設けられており、排出部の構成も実施例1と同様で現像剤収納部材34の開封が進行する開封方向Eに対して略垂直な方向Fに複数の開口部35aおよび複数の開口部35aを定義する連結部35bを有している。即ち、複数の開口部35aは、開封方向Eに垂直な方向Fにずれて配置されている。また、複数の開口部35aは開封部材20の回転軸の方向にずれて配置されている。また、被係合部19bは、複数の開口部35aが並んでいる方向と略垂直方向の封止部材19の一端側に設けられている。また、開封部材20は、複数の開口部35aが並んでいる方向と略垂直方向の封止部材19の一端側に設けられている。固定部は実施例1の第一の固定部16dに相当する開封に必要な固定部16dを有している。成形部34aにより現像剤収納部材34自体が形を保とうとする事と、現像剤収納部材34が枠体に沿った形状であるため枠体に全体的に支えられ現像剤収納部材34が現像剤供給ローラ23や現像ローラ13の方へ移動しにくくなる。   Here, the discharge portion 35 is provided in the molding portion 34a, and the structure of the discharge portion is the same as in the first embodiment, and a plurality of discharge portions 35 are provided in a direction F substantially perpendicular to the opening direction E in which the opening of the developer storage member 34 proceeds. It has the connection part 35b which defines the opening part 35a and the several opening part 35a. That is, the plurality of openings 35 a are arranged so as to be shifted in the direction F perpendicular to the opening direction E. Further, the plurality of openings 35 a are arranged so as to be shifted in the direction of the rotation axis of the opening member 20. The engaged portion 19b is provided on one end side of the sealing member 19 in a direction substantially perpendicular to the direction in which the plurality of openings 35a are arranged. The opening member 20 is provided on one end side of the sealing member 19 in a direction substantially perpendicular to the direction in which the plurality of openings 35a are arranged. The fixing portion has a fixing portion 16d necessary for opening corresponding to the first fixing portion 16d of the first embodiment. The developer accommodating member 34 itself keeps its shape by the molding portion 34a, and the developer accommodating member 34 is supported by the entire frame because the developer accommodating member 34 has a shape along the frame. It becomes difficult to move toward the supply roller 23 and the developing roller 13.

次に固定部の固定の手段としては熱溶着、超音波溶着、接着、枠体間への挟み込み、熱カシメ、超音波カシメ、穴と凸による引っ掛け等が挙げられる。
なお封止部材19、開封部材20の構成は実施例1と同じである。
Next, means for fixing the fixing portion include thermal welding, ultrasonic welding, adhesion, sandwiching between frames, thermal caulking, ultrasonic caulking, hooking by holes and projections, and the like.
The configurations of the sealing member 19 and the opening member 20 are the same as those in the first embodiment.

<現像剤収納袋の開封概要>
次に現像剤収納袋16の開封について述べる。ここで実施例1と固定部、固定部の位置はほぼ同じであり力の関係も同じである。よって開封工程も同じである。(図7、図8)
実施例2で開口部35aは成形部34aに配置されているが、成形部34aも実施例1と同様に可撓性であり、開封時の力の関係は実施例1と同じである。よって実施例2においても開封が進行する方向Eの方向で、第一の接合部22aと第二の接合部22bとを複数の連結部35bが橋渡ししている。そのため第一の接合部22aの開封を終えて第二の接合部22aが開封する時に封止部材19を現像剤収納部材34から剥す力を伝えることができる。そのため第二の接合部22bも開封が可能となるのである。
<Outline of opening the developer storage bag>
Next, the opening of the developer storage bag 16 will be described. Here, the positions of the fixed portion and the fixed portion are substantially the same as in the first embodiment, and the relationship between the forces is also the same. Therefore, the opening process is the same. (Figs. 7 and 8)
In Example 2, the opening 35a is arranged in the molding part 34a, but the molding part 34a is also flexible as in Example 1, and the relationship of the force at the time of opening is the same as in Example 1. Therefore, also in Example 2, the several connection part 35b bridges the 1st junction part 22a and the 2nd junction part 22b in the direction of the direction E in which opening progresses. Therefore, the force for peeling the sealing member 19 from the developer accommodating member 34 can be transmitted when the opening of the first joint portion 22a is completed and the second joint portion 22a is opened. Therefore, the second joint portion 22b can also be opened.

開封後の現像剤排出構についても実施例1と同様である。前述の現像剤収納部材34から封止部材19を開封すると、まず開口部35aは現像剤収納部材34の下方に配置してあるため重力が作用すると同時に開封時の開口部35aの位置が動くことで、現像剤が排出される。また、現像剤収納部材34の振動等により開口部35a付近の現像剤が排出される。ここで開封部材20は押圧部材21を兼ねている。また押圧部材21の回転軸方向に垂直な断面で押圧部材21の断面は四角形をしており実施例1で説明したように押圧部材21の回転により現像剤の排出が促進される(図19)。   The developer discharging mechanism after opening is the same as in the first embodiment. When the sealing member 19 is opened from the developer accommodating member 34, first, the opening 35a is arranged below the developer accommodating member 34, so that gravity acts and simultaneously the position of the opening 35a at the time of opening moves. Then, the developer is discharged. Further, the developer in the vicinity of the opening 35a is discharged by the vibration of the developer storage member 34 or the like. Here, the opening member 20 also serves as the pressing member 21. Further, the cross section of the pressing member 21 is perpendicular to the rotation axis direction, and the cross section of the pressing member 21 is rectangular, and as described in the first embodiment, the discharge of the developer is promoted by the rotation of the pressing member 21 (FIG. 19). .

ここで現像剤収納部材34の開口部35aが設けられている面と同じ面を押圧部材21は接している。なお現像剤収納部材34は開口部35aが設けられている面と他の面とは屈曲部34dを挟んで複数の面から構成されている。   Here, the pressing member 21 is in contact with the same surface as the surface on which the opening 35a of the developer accommodating member 34 is provided. Note that the developer storage member 34 includes a surface on which the opening 35a is provided and another surface including a plurality of surfaces with a bent portion 34d interposed therebetween.

上記のような構成をとることにより実施例1の効果に加えて以下のような効果がある。   In addition to the effects of the first embodiment, the following effects can be obtained by adopting the above configuration.

(真空成形の効果)
現像剤収納部材34の一部を真空成形により形がつくられていることにより以下の効果がある。
(Effect of vacuum forming)
By forming a part of the developer accommodating member 34 by vacuum forming, the following effects can be obtained.

第一の効果として現像剤収納部材34を枠体の内側に沿った形状にできる。そのため実施例1で示すような袋形態では枠体の隅部にまで袋を入れる事は難しく、現像剤収納部材34と第一の枠体17に隙間ができてそのスペースが有効な現像剤収納スペースとならない。   As a first effect, the developer accommodating member 34 can be shaped along the inside of the frame. Therefore, in the bag form as shown in the first embodiment, it is difficult to put the bag up to the corner of the frame body, and there is a gap between the developer storage member 34 and the first frame body 17 so that the space is effective. There is no space.

第二の効果として現像剤収納部材34が枠体に沿った形状にできるので枠体への組み込みか容易となる。これは組み込み時に枠体に押し込んで形状を合わせる事をしなくて済むためである。   As a second effect, the developer accommodating member 34 can be shaped along the frame, so that it can be easily incorporated into the frame. This is because it is not necessary to match the shape by pushing it into the frame during assembly.

第三の効果として現像剤収納部材34が現像剤供給ローラ23や現像ローラ13の方へ移動しにくくなる。これは、真空成形により前述のように現像剤収納部材34自体が形を保とうとする事と、現像剤収納部材34が枠体に沿った形状である事から、現像剤収納部材34が枠体に全体的に支えられるためである。そのため実施例1で示すような像剤供給ローラ23や現像ローラ13の方へ移動を規制する為の第二の固定部を廃止することが可能となる。   As a third effect, the developer accommodating member 34 is less likely to move toward the developer supply roller 23 and the developing roller 13. This is because the developer accommodating member 34 itself keeps its shape by vacuum forming and the developer accommodating member 34 has a shape along the frame. It is because it is supported by the whole. Therefore, it is possible to eliminate the second fixing portion for restricting the movement toward the image agent supply roller 23 and the developing roller 13 as shown in the first embodiment.

また図19で示すように開口部35aが設けられている面と同じ面34fを押す効果は次のようなものがある。現像剤収納部材34は真空成形により複数の面で構成されている。よって複数の面と面との間に屈曲部34dが存在している。現像剤収納部材34の面は屈曲部で囲まれた部分として定義する。ここで開口部35aを含む面34fを押圧した場合と開口部35aを含まない面34eを押圧した場合との効果の差を説明する。面34eは、開口部35aを含む面34fに対し屈曲部34dを挟んだ面である。押圧部材21により押圧された面34eが受ける力は屈曲部34dを経由する。開口部35aを含む面に届く前に屈曲部34dで大きく減衰してしまう。そのため直接開口部35aを有する面34fを押圧した場合に比べ開口部35aを動かす力も小さくなる。そのため開口部35aを動かして現像剤を排出する作用が小さくなる。よって押圧部材21は開口部35aを含む面34fを押圧した方が効率よく内部の現像剤の排出性を向上でき、また現像剤の滞留を防止できるのである。このように開封部材20が兼ねている押圧部材21の回転により現像剤収納部材34を第二の枠体18に押しつけるように押圧することで現像剤収納部材34を変形させて開口部35aの位置を変化させて内部の現像剤を排出する。また開口部35aも複数あるため一つの開口部より排出しやすい。また開口部35aは画像形成時の姿勢で重力方向下向きに配置されているので現像剤を排出しやすい。   Further, as shown in FIG. 19, the effect of pressing the same surface 34f as the surface provided with the opening 35a is as follows. The developer accommodating member 34 is constituted by a plurality of surfaces by vacuum forming. Therefore, the bent portion 34d exists between the plurality of surfaces. The surface of the developer storage member 34 is defined as a portion surrounded by a bent portion. Here, a difference in effect between when the surface 34f including the opening 35a is pressed and when the surface 34e not including the opening 35a is pressed will be described. The surface 34e is a surface that sandwiches the bent portion 34d with respect to the surface 34f including the opening 35a. The force received by the surface 34e pressed by the pressing member 21 passes through the bent portion 34d. Before reaching the surface including the opening 35a, the bending portion 34d attenuates greatly. Therefore, the force for moving the opening 35a is also smaller than when the surface 34f having the opening 35a is pressed directly. Therefore, the action of moving the opening 35a and discharging the developer becomes small. Therefore, when the pressing member 21 presses the surface 34f including the opening 35a, it is possible to improve the discharge performance of the internal developer and to prevent the developer from staying. Thus, the developer accommodating member 34 is deformed by pressing the developer accommodating member 34 against the second frame 18 by the rotation of the pressing member 21 also serving as the opening member 20, and the position of the opening 35a. Is changed to discharge the internal developer. Further, since there are a plurality of openings 35a, it is easier to discharge from one opening. Further, since the opening 35a is arranged downward in the gravitational direction in the posture at the time of image formation, it is easy to discharge the developer.

(開封部材、押圧部材、撹拌部材がそれぞれ別の例)
図35、36を用いて押圧部材21と開封部材20、撹拌部材41がそれぞれ別の部材である場合の例を示す。図35は開封前、図36は開封後の概略断面図である。ここで押圧部材21と開封部材20、撹拌部材41がそれぞれ回転可能に第一の枠体17に支持されており、画像形成装置B本体からの駆動を受けて回転する。開封工程は開封部材20が矢印C方向に回転することで封止部材19が巻き取られ開口部35aが露出する。また押圧部材21の回転に伴い現像剤収納部材34を押圧することで現像剤収納部材34を変形させ現像剤収納部材34内部からのトナーの排出を促す。また撹拌部材41が回転することで現像剤収納部材34から排出されたトナーを撹拌する事ができる。このように押圧部材21と開封部材20、撹拌部材41がそれぞれ別の部材である為に必要に応じてそれぞれの回転方向、回転速度、回転時間、等を設定することができる。
(Opening member, pressing member, and stirring member are different examples)
An example in which the pressing member 21, the opening member 20, and the stirring member 41 are separate members will be described with reference to FIGS. FIG. 35 is a schematic sectional view before opening, and FIG. 36 is a schematic sectional view after opening. Here, the pressing member 21, the opening member 20, and the stirring member 41 are rotatably supported by the first frame 17, and are rotated by receiving a drive from the main body of the image forming apparatus B. In the opening process, the opening member 20 rotates in the direction of arrow C, so that the sealing member 19 is wound up and the opening 35a is exposed. Further, the developer accommodating member 34 is pressed along with the rotation of the pressing member 21 to deform the developer accommodating member 34 and prompt the toner to be discharged from the developer accommodating member 34. Further, when the stirring member 41 rotates, the toner discharged from the developer storage member 34 can be stirred. Thus, since the pressing member 21, the opening member 20, and the stirring member 41 are separate members, the rotation direction, the rotation speed, the rotation time, and the like can be set as necessary.

(開封動作が回転以外の例)
図37、図38を用いて開封部材20が回転ではなく、固定部18aから離れる方向に移動し開口部35aを露出する場合の例を示す。ここで開封部材20の両端部は第一の枠体17にスライド可能に支持されている。また開封部材20は画像形成装置B本体もしくはユーザーの操作により動かす事が可能となっている。ここで開封部材20が矢印C2方向に移動する。この開封部材20の移動に伴い封止部材19が矢印D方向に引っ張られ溶着部22a、22bを剥がし開口部35aを露出させる。なおスライド方向C2は直線に限らず円弧状などでも、開封部材20が固定部19aから離れる方向に移動可能であれば良い。
(Example of opening operation other than rotation)
An example in which the opening member 20 is not rotated but moved away from the fixed portion 18a to expose the opening 35a with reference to FIGS. Here, both end portions of the opening member 20 are slidably supported by the first frame body 17. Further, the opening member 20 can be moved by the operation of the image forming apparatus B main body or the user. Here, the opening member 20 moves in the direction of the arrow C2. As the opening member 20 moves, the sealing member 19 is pulled in the direction of arrow D to peel off the welded portions 22a and 22b to expose the opening 35a. The sliding direction C2 is not limited to a straight line, but may be an arc shape or the like as long as the unsealing member 20 can move in a direction away from the fixing portion 19a.

また開封部材20は開封後にも繰り返し往復運動を行うことで排出時の押圧部材21として兼用する事や、排出後のトナーの撹拌部材としてとして兼用しても良い(図39)。
このように開封部材20の動作を回転以外でも封止部材19を移動可能に構成できるため必要に応じ適宜開封部材20の動作する構成を選択可能となる。
Further, the opening member 20 may also be used as the pressing member 21 at the time of discharging by repeatedly reciprocating after opening, or as the stirring member for the toner after discharging (FIG. 39).
As described above, the operation of the opening member 20 can be configured so that the sealing member 19 can be moved other than by rotation, so that the configuration in which the opening member 20 operates can be selected as necessary.

(ユーザーによる開封動作、画像形成装置による開封動作の例)
開封部材20を用いずに封止部材19の一部、もしくは封止部材19に連結した部材をユーザーが引っ張る事により開口部35aを露出させても良い。図45、図46に示すように封止部材19が第一の枠体の開口部17aを通りプロセスカートリッジAの外側に露出している部分(以下封止部材把持部19eとする)を有した構成となっている。なお開口部17aにはトナーが外部に漏れないようにするためのシール部材(不図示)を有している。封止部材作用部19eをユーザーがプロセスカートリッジAの使用前に矢印C3方向に移動させる事により開口部35a露出することができる
また封止部材把持部19eに把持しやすいように別部材を設けても良い。
(Example of opening operation by the user and opening operation by the image forming device)
The opening 35 a may be exposed by pulling a part of the sealing member 19 or a member connected to the sealing member 19 without using the opening member 20. 45 and 46, the sealing member 19 has a portion exposed to the outside of the process cartridge A through the opening 17a of the first frame (hereinafter referred to as a sealing member gripping portion 19e). It has a configuration. The opening 17a has a seal member (not shown) for preventing the toner from leaking outside. The opening 35a can be exposed by the user moving the sealing member operating portion 19e in the direction of the arrow C3 before using the process cartridge A. Also, another member is provided so that the sealing member holding portion 19e can be easily gripped. Also good.

なおユーザーの手を煩わせずに封止部材把持部19eを画像形成装置B本体に駆動手段を設け引っ張り開口部35aを露出させても良い。またプロセスカートリッジAを画像形成装置Bに装着時の装着動作で封止部材把持部19eを移動させ開口部35aを露出させても良い。そして開口部35aを露出させた後は押圧部材21を回転させて押圧シート21bで現像剤収納部材34を押圧し内包した現像剤を排出させる(図40)。   Note that the sealing member gripping portion 19e may be provided on the main body of the image forming apparatus B to expose the pulling opening 35a without bothering the user. The opening 35a may be exposed by moving the sealing member gripping portion 19e in the mounting operation when mounting the process cartridge A to the image forming apparatus B. After the opening 35a is exposed, the pressing member 21 is rotated to press the developer containing member 34 with the pressing sheet 21b and discharge the contained developer (FIG. 40).

(補給系構成に用いた例)
現像剤袋16と現像剤袋16を覆う補給枠体42を一体的に補給ユニット43としてプロセスカートリッジA2に取り外し可能に構成した例を述べる。図47、図48で示すように補給ユニット43は補給枠体42と開封部材20と封止部材19を有した現像剤袋16から構成される。またプロセスカートリッジA2は、感光体ドラム11の周囲に帯電手段である帯電ローラ12、そしてクリーニング手段として弾性を有するクリーニングブレード14を有するクリーナーユニット24、現像装置38を備えている。現像装置38は、現像手段である現像ローラ13と現像ブレード15、現像剤供給ローラ23、そして補給ユニット43が着脱可能に構成されている。
(Example used for replenishment system configuration)
An example will be described in which the developer bag 16 and the supply frame body 42 covering the developer bag 16 are integrally configured as a supply unit 43 so as to be removable from the process cartridge A2. As shown in FIGS. 47 and 48, the supply unit 43 includes the developer bag 16 having the supply frame body 42, the opening member 20, and the sealing member 19. Further, the process cartridge A2 includes a charging roller 12 as a charging unit around the photosensitive drum 11, a cleaner unit 24 having an elastic cleaning blade 14 as a cleaning unit, and a developing device 38. The developing device 38 is configured such that the developing roller 13 and the developing blade 15, the developer supply roller 23, and the replenishment unit 43 that are developing means are detachable.

この補給ユニット43をプロセスカートリッジA2に装着し、一体的に画像形成装置Bの本体内へ着脱可能にしている。なお、プロセスカートリッジA2を画像形成装置B本体内に装着したままで補給ユニット43を交換可能としてもよい。   The replenishment unit 43 is mounted on the process cartridge A2 so as to be detachable integrally with the main body of the image forming apparatus B. The replenishment unit 43 may be replaceable while the process cartridge A2 is mounted in the image forming apparatus B main body.

ここで開封部材20が矢印Cの方向に回転する事で封止部材19は矢印Dの方向へ移動して開口部35aを露出する。   Here, as the opening member 20 rotates in the direction of arrow C, the sealing member 19 moves in the direction of arrow D to expose the opening 35a.

そして封止部材19を現像剤袋16より剥離後は開封部材20と兼用している押圧部材21で現像剤袋16を押圧しトナーを排出する(図49)。   After the sealing member 19 is peeled from the developer bag 16, the developer bag 16 is pressed by the pressing member 21 that also serves as the opening member 20, and the toner is discharged (FIG. 49).

このように現像剤袋16を内包した補給ユニット43を交換することでトナーを補給可能なプロセスカートリッジA2を提供できる。   Thus, by replacing the supply unit 43 containing the developer bag 16, the process cartridge A2 capable of supplying toner can be provided.

(現像剤袋16内の現像剤循環作用活性化)
次に、図19、図41、図42、図43、図44を用いて現像剤袋16内の現像剤循環作用を活性化させる構成と作用について説明する。図41は、現像装置38の押圧部材21の回転中心軸に垂直な断面図である。
(Activation of developer circulation in developer bag 16)
Next, the configuration and operation for activating the developer circulating action in the developer bag 16 will be described with reference to FIGS. 19, 41, 42, 43, and 44. FIG. 41 is a cross-sectional view perpendicular to the rotation center axis of the pressing member 21 of the developing device 38. FIG.

実施例1で述べた様に、現像剤袋16内の現像剤循環は、現像剤袋16が変形することでおこることは先に述べた。ここで、実施例2で述べた成形品34を使用した場合、現像剤袋16の形状が、枠体17と同じ様な形状をとることが可能になることより図19に示す様に現像剤袋16と枠体17が密着する領域が増える。このことで押圧部材21による現像剤袋16の変形可能領域が制限され、結果現像剤袋内16の現像剤循環も制限される場合がある。従って、現像剤袋16内の現像剤循環作用がより必要な場合は、図41に示す様に現像剤袋16の開口を有する面34fと屈曲部34dを挟んで連続した面34eと、枠体17の間に隙間αを設ける。この隙間αは現像剤袋16を振幅させる量に応じて設定すれば良い。ここで、前記隙間αを押圧部材21による現像剤袋16の振幅以上の値に設定した時は、前述現像剤の循環作用は、現像剤袋16の振幅に比例するので現像剤の循環作用は最大限発揮される。しかし、この場合隙間αにより生じた容積分、現像剤の収容量が制限される。次に、前記隙間αを現像剤袋16の振幅未満に設定した場合は、現像剤の循環作用は制限されたものとなる。この場合は、前記現像剤袋16の振幅以上の隙間αを開けた場合に比べて、隙間αが減少した分現像剤の収納量を増やす方向に振り分ける事が可能になる。従って、前記隙間αの値は、求める現像剤袋16内の現像剤循環作用と、収納したい現像剤の量に応じて適宜設定すれば良い。また、図41に示す様に、開口を有する面34fと前記開口を有する面と相対する面34hの間に向けて、前記隙間αを小さくした構成としてもよい。つまり隙間αは、開口部を形成する面34fに近づくほど、大きくなるように構成されている。このような構成の方が、開口を有する面34fと屈曲部34dを挟んで連続した面34e全域に隙間αを設ける構成よりも、現像剤袋16内の現像剤循環と現像剤の収納量のバランスをより取りやすい構成とすることができる。なお屈曲部34dは、面取りで構成されたもの(図51(b))、複数の面で構成されたもの(図51(d))、また曲率が0に近い小さなもの(図51(a))から曲率が大きいもの(図51(c))まで適宜選定して良い。   As described in the first embodiment, the developer circulation in the developer bag 16 is caused by the deformation of the developer bag 16 as described above. Here, when the molded product 34 described in Example 2 is used, the developer bag 16 can have the same shape as that of the frame 17, so that the developer as shown in FIG. The region where the bag 16 and the frame 17 are in close contact with each other increases. As a result, the deformable region of the developer bag 16 by the pressing member 21 is limited, and as a result, the developer circulation in the developer bag 16 may be limited. Therefore, when the developer circulation action in the developer bag 16 is more necessary, as shown in FIG. 41, the surface 34f having the opening of the developer bag 16 and the continuous surface 34e across the bent portion 34d, and the frame body A gap α is provided between 17. The gap α may be set according to the amount by which the developer bag 16 is amplituded. Here, when the gap α is set to a value greater than or equal to the amplitude of the developer bag 16 by the pressing member 21, the developer circulating action is proportional to the amplitude of the developer bag 16, so the developer circulating action is It is demonstrated to the fullest. However, in this case, the developer capacity is limited by the volume generated by the gap α. Next, when the gap α is set to be less than the amplitude of the developer bag 16, the circulation action of the developer is limited. In this case, as compared with the case where the gap α larger than the amplitude of the developer bag 16 is opened, it is possible to distribute the developer in a direction in which the developer storage amount is increased as the gap α is reduced. Therefore, the value of the gap α may be appropriately set according to the developer circulation action in the developer bag 16 to be obtained and the amount of developer to be stored. In addition, as shown in FIG. 41, the gap α may be configured to be small between a surface 34f having an opening and a surface 34h facing the surface having the opening. That is, the gap α is configured to increase as it approaches the surface 34f that forms the opening. In this configuration, the developer circulation in the developer bag 16 and the amount of developer stored in the developer bag 16 are greater than the configuration in which the gap α is provided over the entire surface 34e across the surface 34f having the opening and the bent portion 34d. It can be set as the structure which is easy to take a balance. The bent portion 34d is formed by chamfering (FIG. 51 (b)), is formed by a plurality of surfaces (FIG. 51 (d)), and has a small curvature close to 0 (FIG. 51 (a)). ) To those having a large curvature (FIG. 51 (c)) may be selected as appropriate.

以上、押圧部材21の回転中心軸に垂直な断面における隙間αの構成について説明したが、次に図42、図43、図44を用いて、押圧部材21の回転中心軸と平行な方向の断面における隙間βの構成について説明する。図42は、現像剤収納容器30の斜視図である。図43は、図41に示すVV断面である。図44は、図41に示す枠体17のみをVVでカットした斜視図である。   The configuration of the gap α in the cross section perpendicular to the rotation center axis of the pressing member 21 has been described above. Next, with reference to FIGS. 42, 43, and 44, the cross section in the direction parallel to the rotation center axis of the pressing member 21. The configuration of the gap β in FIG. FIG. 42 is a perspective view of the developer storage container 30. 43 is a VV cross section shown in FIG. FIG. 44 is a perspective view in which only the frame body 17 shown in FIG. 41 is cut by VV.

図42に示す様に、開口を有する面34fと屈曲部34dを挟んで連続した面34eおよび34gは押圧部材21回転中心軸方向の両側と通気部34bと対向する面の3面ある。
ここで、図43に示す様に、押圧部材21の回転中心軸の長手方向の面34gと枠体17の間にそれぞれ隙間を設けている。隙間の設定の仕方は前述押圧部材の回転軸中心軸と垂直な断面と同様である。
As shown in FIG. 42, there are three surfaces 34e and 34g that are continuous across the surface 34f having the opening and the bent portion 34d, that is, both surfaces in the direction of the rotation center axis of the pressing member 21 and the surface facing the ventilation portion 34b.
Here, as shown in FIG. 43, a gap is provided between the longitudinal surface 34 g of the rotation center axis of the pressing member 21 and the frame body 17. The method of setting the gap is the same as that of the cross section perpendicular to the central axis of the pressing member.

また、現像剤循環作用については、実施例1で述べた作用と同様である。
以上、述べた様に現像剤袋16内の現像剤の循環をより活性化することが可能になる。
The developer circulation action is the same as that described in the first embodiment.
As described above, the circulation of the developer in the developer bag 16 can be further activated.
