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容器、現像剤収納ユニット、プロセスカートリッジに関するものである。   The present invention relates to an image forming apparatus, a developer container used in the image forming apparatus, a developer storage unit, and a process cartridge.

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、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)、電子写真ファクシミリ装置が含まれる。   Here, the image forming apparatus is, for example, an apparatus that forms an image on a recording medium using an electrophotographic image forming process, and includes an electrophotographic copying machine, an electrophotographic printer (for example, an LED printer, a laser beam printer), and an electrophotographic facsimile. Device included.

また、プロセスカートリッジとは、少なくとも像担持体と、それに作用するプロセス手段を有し、画像形成装置本体に着脱可能にしたものをいう。   The process cartridge means a cartridge having at least an image carrier and process means acting on the image carrier and detachable from the main body of the image forming apparatus.

また、現像剤容器および現像剤収納ユニットは、画像形成装置またはカートリッジに収納または着脱可能なものである。   The developer container and the developer storage unit can be stored in or removed from the image forming apparatus or the cartridge.

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23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を開封する方式が広く採用されている。   In such a process cartridge, as shown in FIG. 23, the opening provided in the developer storage frame 31 for storing the developer (toner, carrier, etc.) is sealed with a sealing member. A method of opening the opening by peeling off the joint portion 33 of the toner seal 32 as a sealing member during use is widely adopted.

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こと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、特許文献2)。   Further, there has been devised an apparatus using an internal container that can be deformed against the scattering of the developer in the process cartridge in the developer filling process at the time of manufacturing the process cartridge (Patent Documents 1 and 2).

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.

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. Here, the return angle Q of the sealing member 19 is preferably 90 degrees or less. The folding angle Q is the included angle Q between the surface of the joint portion 22 of the developer container 26 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、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固定部16d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 fixing portion 16d in this embodiment. Other than ultrasonic caulking, similar to the means of the fixing portion 16d, heat welding, ultrasonic welding, adhesion, pinching between frames, hooking by holes and protrusions, etc. may be used.

(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。そして現像剤収納容器26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 container 26 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収納容器26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、現像剤収納容器26と封止部材19は図10に示すような現像剤収納容器26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 container 26 is folded back in the direction in which the opening proceeds (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 in this way, the developer container 26 and the sealing member 19 have a surface along the direction D in which the sealing member 19 is pulled and the surface of the joint 22 of the developer container 26 as shown in FIG. The inclined peeling position relationship is such that the included angle 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を移動させ現像剤収納容器26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と、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 storage container 26. The opening member 20 has a shaft-shaped support portion (not shown) that is rotatably supported by the second frame 18 at both ends, and an engagement portion 20b that fixes the engaged portion 19b of the sealing member 19. ,have. 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.

In FIG.5 (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 storage container 30 due to the force at the time of opening. Further, in this embodiment, the fixing portion 18a of the frame body and the fixing portion 16d of the developer storage container 30 are joined by ultrasonic caulking from the joining portion 22 in FIGS. 5B, 5C, and 11A. As shown, the portion close to the joint portion 22 of the ultrasonic caulking portion of the fixing portion 18a becomes the fixing portion 18c.

まず図4で示すように開封部材20は不図示の本体からの駆動手段により駆動力が伝達され矢印Cの方向に回転する。   First, as shown in FIG. 4, the unsealing member 20 is rotated in the direction of arrow C by the driving force transmitted by the driving means from the main body (not shown).

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(b)、図12に示す。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。   5 (b) and FIG. 12 show a state immediately before the sealing member 19 is pulled by the rotation of the unsealing member 20 and the unsealing of the first joint portion 22a starts. 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を介して現像剤収納容器30が引っ張られる。すると現像剤収納容器30は固定部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に向けて現像剤収納容器30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5(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 storage container 30 is pulled through the joint portion 22. As a result, a force is applied to the fixing portion 16d of the developer container 30, and the developer container 30 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 the 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 direction closer to the rotation axis of the opening member 20 (FIG. 5B). . 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5(b)が力点部20aが角部(c)の状態を示し、図5(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. 5B shows a state where the force point portion 20a is the corner portion (c), and FIG. 5C shows a state where the rotation of the unsealing member 20 further proceeds and the force point portion moves to the corner portion 20d.

図5(c)、図13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35aが露出する。開口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11(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、現像剤収納容器30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11(b)、図14)。そして現像剤収納容器30内部の現像剤が排出部35の開口35aを通り矢印Iの方向に排出される。   As shown in FIG. 5C and FIG. 13, as the rotation of the unsealing member 20 proceeds, the unsealing proceeds and the return portion 19d also proceeds in the direction of arrow E. Further, the opening is further advanced and the opening 35a is exposed. FIG. 11A 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 force point portion 20a, and the developer container 30 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.11 (b), FIG.14). Then, the developer inside the developer container 30 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。   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.

また封止部材19が返し部19dを設けることで接合部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。   Further, 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 opened reliably.

また複数の開口35aが並んでいる方向Fと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。   In addition, an engaged portion 19b to be engaged with the opening member 20 for opening the sealing member 19 is provided on one end side of the sealing member 19 in the direction perpendicular to the direction F in which the plurality of openings 35a are arranged. The sealing member 19 can be reliably engaged and opened.

また枠体に固定部18cを設けて、現像剤収納容器26を開封時に支持することにより可撓性を有し変形可能な現像剤収納容器26でも確実に開封可能となる。   Further, by providing the frame 18 with the fixing portion 18c and supporting the developer storage container 26 at the time of opening, the flexible and deformable developer storage container 26 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5(a)→図5(b)→図5(c)→図11(a))。この動きにより開口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。   As for the developer discharge 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. 5A → FIG. 5B → FIG. 5C). ) → FIG. 11 (a)). By this movement, the developer around the opening 35a is moved, and the aggregation of the developer can be broken.

(開封に関係する固定部の配置関係)
図4、図12に示すように第一の接合部22aを確実に剥がすためには第一の接合部22a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収納容器26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しにくい。
(Relationship of fixed parts related to opening)
As shown in FIGS. 4 and 12, the following arrangement relationship is required between the first joint portion 22 a and the fixing portion 18 c in order to reliably peel off the first joint portion 22 a. 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 fixing 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 storage container 26 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 is difficult to open.

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.

<押圧部材と構成概要について>
図15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 configuration outline>
As shown in FIG. 15, the pressing member 21 includes a shaft portion 21 a and a pressing sheet 21 b fixed to the shaft portion 21 a, and is rotatably provided 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(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 (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21aと共に回転する。なお押圧シート21b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 portion 21a. Note that the tip of the pressing sheet 21b protrudes outside the circumscribed circle of the shaft portion 21a. 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15、図16に示すように押圧シート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. 15 and 16, 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.

<現像剤収納容器からの現像剤排出概要について>
(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5、図11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)、現像剤収納容器30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35aの位置が変化することにより開口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 container>
(Outline of discharge before opening from before opening)
First, as shown in FIG. 5 and FIG. 11, 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 storage container 30 is It is supported by the fixing 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 joining portion 22a is opened, the opening 35a By changing the position, it is possible to prevent the developer from staying in the vicinity of the opening 35a, and the discharge property is good.

(開封後の排出概要 押圧時)
開封後は図11(b)に示すように前述の現像剤収納容器30から封止部材19を開封すると、開口35aが現像剤収納容器30の下方に開くように配置してある。このため、重力の作用と開封時の現像剤収納容器30の振動等により開口35a付近の現像剤が排出される。
(Outline of discharge after opening)
After opening, as shown in FIG. 11 (b), when the sealing member 19 is opened from the developer container 30 described above, the opening 35 a is arranged to open below the developer container 30. For this reason, the developer in the vicinity of the opening 35a is discharged due to the action of gravity and the vibration of the developer container 30 when opened.

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収納容器30を押す押圧シート21bも回転し、図14で示すように現像剤収納容器30により開封部材20に巻き着く。ここで図15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収納容器30を矢印J方向に押す。この時、現像剤収納容器30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収納容器30全体が変形する。また現像剤収納容器30は押圧シート21bにより押され内容積が少なくなる。このように現像剤収納容器30の容積減と全体形状の変化により、現像剤収納容器30の内部の現像剤は撹拌され、それにより開口35aから現像剤が排出されやすくなる。この時、現像剤収納容器30の開口35a以外は閉じており開口35a以外に現像剤の逃げ道が無いため開口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 storage container 30 fixed to the opening member 20 also rotates, and is wound around the opening member 20 by the developer storage container 30 as shown in FIG. Reach. Here, since the pressing sheet 21b has elasticity as shown in FIG. 15, the developer container 30 is pushed in the direction of the arrow J in order to restore the original shape. At this time, the developer storage container 30 is pressed against the second frame 18 via the toner stored by being pressed by the pressing sheet 21b, and the entire developer storage container 30 is deformed. Further, the developer container 30 is pushed by the pressure sheet 21b, and the internal volume is reduced. Thus, the developer inside the developer container 30 is agitated by the volume reduction of the developer container 30 and the change in the overall shape, thereby making it easier to discharge the developer from the opening 35a. At this time, the portions other than the opening 35a of the developer storage container 30 are closed, 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、現像剤収納容器30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収納容器30は変形できる。   The developer container 30 can be deformed as long as at least a part of the developer container 30 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, the developer can be easily supplied to the entire longitudinal direction of the developing roller 13 when 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が現像剤収納容器30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 containing container 30 against the second frame 18 provided in the frames 17 and 18.

(開封後の排出概要 現像剤収納容器形状回復)
そして、図16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が現像剤収納容器30から離れる。この時、現像剤収納容器30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が回転し、図15で示すように現像剤収納容器30を第二の枠体18に押し現像剤収納容器30が変形することで開口35a付近以外の現像剤も動かされ開口35aより排出される。
(Outline of discharge after opening the developer container shape recovery)
Then, as shown in FIG. 16, the rotation of the opening member 20 further advances and the pressing sheet 21 b is separated from the developer storage container 30. At this time, since the developer storage container 30 has flexibility, the developer storage container 30 tries to recover to a state before being pressed by the weight of the developer stored (arrow K). Then, the pressing sheet 21b is rotated, and the developer container 30 is pushed to the second frame 18 as shown in FIG. 15, and the developer container 30 is deformed to move the developer other than the vicinity of the opening 35a. It is discharged from the opening 35a.

(開封後の排出概要 押圧/回復の繰り返し)
開封直後の現像剤が現像剤収納容器30内部に多くある場合は押圧シート21bおよび開封部材20の現像剤収納容器30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収納容器30を変形させる。この押圧部材21の押圧による現像剤収納容器30の収縮と、現像剤収納容器30内部の現像剤の重さと現像剤収納容器30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収納容器30自体が動くため現像剤収納容器30が振動し、この振動によっても現像剤収納容器30内部の現像剤が開口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収納容器30を押圧させることができる。
(Outline of discharge after opening, repeated pressing / recovery)
When there is a lot of developer immediately after opening in the developer storage container 30, the amount of intrusion of the pressing sheet 21 b and the opening member 20 into the developer storage container 30 is repeatedly changed, and development is performed so as to press against the second frame 18. The agent storage container 30 is deformed. The contraction of the developer container 30 due to the pressing of the pressing member 21 and the recovery due to the weight of the developer inside the developer container 30 and the flexibility of the developer container 30 are repeated. Further, because the developer container 30 itself moves due to the above action, the developer container 30 vibrates, and the developer inside the developer container 30 is also discharged from the opening 35a by this vibration. Further, since the pressing member 21 rotates, the developer storage container 30 can be repeatedly pressed.

<組み立て時の現像剤収納容器の変形の影響>
現像剤収納部材37は、シート状の素材を真空成形等により製造したものを使用している。そのため、可撓性を有することを利用して、充填のための注入口39を容易に形成でき、現像剤収納容器26を枠体の形状に倣わせて組むことができる。そのため、現像剤収納容器26の製造工程で、現像剤収納容器26を変形させて組み立てる工程が発生しうる。
<Effect of deformation of developer storage container during assembly>
As the developer storage member 37, a sheet-shaped material manufactured by vacuum forming or the like is used. Therefore, utilizing the flexibility, the filling port 39 for filling can be easily formed, and the developer container 26 can be assembled following the shape of the frame. Therefore, in the manufacturing process of the developer storage container 26, a process of deforming and assembling the developer storage container 26 may occur.

ここでは、前述した現像剤収納部材37に現像剤を充填する充填工程における現像剤収納容器の変形の影響を図6、図17および図18を用いて述べる。ここで、図17は注入口39形成時における成形された現像剤収納部材37の説明図、図18は本発明の実施形態でない場合の注入口39形成時における成形された現像剤収納部材37の説明図である。   Here, the influence of the deformation of the developer container in the filling step of filling the developer container 37 with the developer will be described with reference to FIGS. 6, 17 and 18. Here, FIG. 17 is an explanatory view of the molded developer storage member 37 when the injection port 39 is formed, and FIG. 18 is an illustration of the molded developer storage member 37 when the injection port 39 is formed in the case of not being an embodiment of the present invention. It is explanatory drawing.

図17に示すように、現像剤収納部材37は、収納した現像剤を排出するために排出部35を備え、排出部35を覆うように、封止部材19が貼り付けられている。成形された現像剤収納部材37は、開口を有する面34f、開口を含まない面34e、および現像剤収納部材37を容器として形作るための側面34gを有する。   As shown in FIG. 17, the developer storage member 37 includes a discharge portion 35 for discharging the stored developer, and the sealing member 19 is attached so as to cover the discharge portion 35. The molded developer storage member 37 has a surface 34f having an opening, a surface 34e not including the opening, and a side surface 34g for forming the developer storage member 37 as a container.

現像剤収納部材37に、注入口39を形成すると、図6に示すように、注入口39の断面形状を変化させる必要があり、それによって現像剤収納部材37の断面の形状を決めている側面34gの形状も変形する。側面34gの形状が変形することで、側面34gに面した他の面34e、34fも変形する。そして、開口を含まない面34e、開口を有する面34f、側面34gのいずれも変形し、それぞれの面に、変曲部40が発生する。   When the inlet 39 is formed in the developer accommodating member 37, it is necessary to change the cross-sectional shape of the inlet 39 as shown in FIG. The shape of 34g is also deformed. By deforming the shape of the side surface 34g, the other surfaces 34e and 34f facing the side surface 34g are also deformed. Then, all of the surface 34e not including the opening, the surface 34f having the opening, and the side surface 34g are deformed, and the inflection portion 40 is generated on each surface.

ここで本発明を適用せず、組み立て時に、接合部22iに予期せぬ部分剥離が発生した例について図18を用いて述べる。接合部22は、「ロの字」形状で連続して形成された閉じた領域22iのみ設けられている。製造工程において、封止部材19が貼り付けられた開口を有する面34fが変形すると、前述した「ロの字」形状で形成された排出部35を封止している接合部の閉じた領域22iも変形し、開口を有する面34fで変曲部40を含む凹凸形状の変形が発生する。この変形により、排出部35を封止している接合部22iの一部に意図せぬ剥離力が掛かり、部分剥離41が起こりうる。   Here, an example in which unexpected partial peeling occurs in the joint portion 22i during assembly without applying the present invention will be described with reference to FIG. The joining portion 22 is provided only with a closed region 22i continuously formed in a “R” shape. In the manufacturing process, when the surface 34f having the opening to which the sealing member 19 is attached is deformed, the closed region 22i of the joint portion that seals the discharge portion 35 formed in the above-described "b" shape. Is also deformed, and deformation of the concavo-convex shape including the inflection portion 40 occurs on the surface 34f having the opening. Due to this deformation, an unintended peeling force is applied to a part of the joining portion 22i sealing the discharge portion 35, and a partial peeling 41 may occur.

本実施例では、図17に示すように、「ロの字」形状で形成された接合部の閉じた領域22iの接合部を延伸させた第一の短手突起部22g1、22g2、第二の短手突起部22h1、22h2を設けている。また、接合部を延伸させた長手突起部22g3、22g4、22h3、22h4を設けている。接合部22と開口を有する面34fの貼り合わせ強度を上げることで、開口を有する面34fの変形を抑えることができる。また、開口を有する面34fで変形が発生しても、突起部22g、22hを設けているため、「ロの字」形状で形成された接合部22iに変形による剥離力が直接掛からないように抑えることができる。   In the present embodiment, as shown in FIG. 17, the first short protrusions 22g1, 22g2, and the second short protrusions 22g1 formed by extending the joints of the closed region 22i of the joints formed in the “B” shape are formed. Short projections 22h1 and 22h2 are provided. In addition, longitudinal protrusions 22g3, 22g4, 22h3, and 22h4 are provided by extending the joint. By increasing the bonding strength between the bonding portion 22 and the surface 34f having an opening, deformation of the surface 34f having an opening can be suppressed. Further, even if deformation occurs on the surface 34f having the opening, the protruding portions 22g and 22h are provided, so that the peeling force due to the deformation is not directly applied to the joint portion 22i formed in the "B" shape. Can be suppressed.

また、本実施例においては、現像剤収納容器26の長い方向の片側端部に、注入口39を形成したが、短い方向の端部に注入口39を形成しても同様である。また、充填工程のみだけでなく、他の組み立て等においても、現像剤収納部材37の可撓性を利用して、現像剤収納容器26を変形させる場合は、同様の効果を得ることができる。更に、本実施例では、可撓性を有する可撓性容器を現像剤収納容器26として用いた場合の説明を行ったが、シートを貼り合わせて構成された現像袋を用いても、現像袋を変形させて組み立てる工程がある場合は、同様の効果を得ることができる。   In this embodiment, the injection port 39 is formed at one end of the developer container 26 in the long direction. However, the same applies to the case where the injection port 39 is formed at the end of the short direction. Further, not only in the filling process, but also in other assembling, the same effect can be obtained when the developer storage container 26 is deformed by utilizing the flexibility of the developer storage member 37. Further, in this embodiment, the case where a flexible container having flexibility is used as the developer container 26 has been described. However, even if a developing bag formed by bonding sheets is used, the developing bag is used. If there is a process of deforming and assembling, the same effect can be obtained.

<接合部の突起部の開封性への影響>
次に接合部の突起部22g、22hを設けた現像剤収納容器26の開封について図8を用いて述べる。
<Influence on the unsealing property of the protrusion of the joint>
Next, the opening of the developer storage container 26 provided with the projections 22g and 22h of the joint will be described with reference to FIG.

前述したように、開封部材20が回転することで、封止部材19が引っ張られて、現像剤収納容器26の開封を行う。開封部材20の回転が進むことで封止部材19が引っ張られて接合部22の開封が始まるが、本実施例では、第一の接合部22aより先に開封される位置に、第一の短手突起部22g1、22g2を設けている。このため、まず第一の短手突起部から開封が始まる。開封により封止部材19が引っ張られる力(矢印D)に対して、第一の接合部22aの長い方向の幅よりも、第一の短手突起部22g1、22g2の幅の方が小さいため、引っ張られる力(矢印D)を集中して受けることができる。そのため、より確実に開封を開始することができ、前述した構成も同様に有していることから、確実に開封を完了することができる。このように、開封を行う接合部に突起部22g、22hを設けた構成で、従来より確実に開封を開始することができ、開封性と可撓性容器の変形による封止部材の剥離防止の効果と両立できる。   As described above, when the opening member 20 rotates, the sealing member 19 is pulled, and the developer container 26 is opened. As the rotation of the unsealing member 20 proceeds, the sealing member 19 is pulled and the unsealing of the joint portion 22 begins. In this embodiment, the first short portion is located at a position where the unsealing portion 20 is unsealed. Hand projections 22g1 and 22g2 are provided. For this reason, opening is first started from the first short protrusion. Since the width of the first short protrusions 22g1 and 22g2 is smaller than the width in the long direction of the first joint 22a with respect to the force (arrow D) that pulls the sealing member 19 by opening, The pulling force (arrow D) can be received in a concentrated manner. Therefore, opening can be started more reliably, and since the above-described configuration is also provided, the opening can be completed with certainty. In this way, with the configuration in which the protrusions 22g and 22h are provided at the joint for opening, the opening can be started more reliably than before, and the opening of the sealing member due to the deformation of the flexible container can be prevented. It is compatible with the effect.

本実施形態によれば、製造時における可撓性容器の変形による封止部材の開封防止特性を向上させることができる。また、製造時だけでなく物流時の衝撃に対しても封止部材の開封防止特性を向上させることができる。   According to this embodiment, the opening prevention characteristic of the sealing member due to deformation of the flexible container at the time of manufacture can be improved. Further, the unsealing property of the sealing member can be improved not only at the time of manufacturing but also at the time of physical distribution.

実施例2として、突起部22g、22hの別の実施形態について図19を用いて述べる。実施例1では、「ロの字」形状の長辺方向(方向F)と短辺方向(方向E)の4本の接合部から境界領域を経て延伸している突起部について述べた。本実施例では図19に示すように、接合部22iの長辺方向および短辺方向と異なる方向に延伸し、かつ接合部の形成されている面で開口から離れる方向に延伸している突起部22g、22hを設けている。突起部は、「ロの字」形状の接合部の角部から開口から離れる方向に延伸している。衝撃の受ける方向によって、延伸させる方向は適宜選択できる。本実施例では、長辺方向および短辺方向とから45°ずれている方向に延伸している突起部を示している。開封方向が短辺方向になる場合は、短辺方向から10°から30°程度ずれた方向に延伸しているのが好ましい。これは長辺方向からの変形に対しても突起部でまずその変形を受けることができるためである。   As Example 2, another embodiment of the protrusions 22g and 22h will be described with reference to FIG. In the first embodiment, the protrusions extending from the four junctions in the long side direction (direction F) and the short side direction (direction E) of the “R” shape through the boundary region are described. In this embodiment, as shown in FIG. 19, the protruding portion extends in a direction different from the long side direction and the short side direction of the bonding portion 22 i and extends in a direction away from the opening on the surface where the bonding portion is formed. 22g and 22h are provided. The protrusion extends from the corner of the “B” -shaped joint in a direction away from the opening. The extending direction can be appropriately selected depending on the direction of impact. In the present embodiment, projections extending in a direction deviated by 45 ° from the long side direction and the short side direction are shown. When the opening direction is the short side direction, it is preferably stretched in the direction deviated by about 10 ° to 30 ° from the short side direction. This is because the deformation can be first subjected to the deformation even in the deformation from the long side direction.

このような構成にしても、突起部22g1、22g2、22h1、22h2を設けたことで、現像剤収納容器26を変形させるような場合が発生しても、容器と接合部22iの貼り合わせ強度を上げ、開口を有する面34fの変形を抑えることができる。また、「ロの字」形状の接合部22iに変形による剥離力が直接掛かるのを抑えることができる。   Even in such a configuration, by providing the protrusions 22g1, 22g2, 22h1, and 22h2, even if the developer storage container 26 is deformed, the bonding strength between the container and the joint 22i can be increased. The deformation of the surface 34f having the opening can be suppressed. In addition, it is possible to prevent the peeling force due to the deformation from being directly applied to the “b” -shaped joint portion 22 i.

また、開封に関しても、実施例1と同様の構成をとるため、確実に開封を行うことができ、可撓性容器の変形による封止部材の剥離防止の効果と両立できる。   Further, regarding the opening, since the same configuration as that of Example 1 is adopted, the opening can be surely performed, and the effect of preventing the peeling of the sealing member due to the deformation of the flexible container can be achieved.

また、「ロの字」形状で形成された接合部22iの4つの角部に接合部を延伸させた突起部について説明したが、例えば、充填工程のみで現像剤収納容器26の変形が発生するのであれば、現像剤を充填する注入口39側のみに、突起部を設けても構わない。例えば、図20に示すような突起部22g1、22g3、22h1、22h3を設けるような場合である。   In addition, the description has been given of the protrusions in which the joint portions are extended to the four corners of the joint portion 22i formed in the “R” shape. However, for example, the developer container 26 is deformed only in the filling process. In this case, a protrusion may be provided only on the injection port 39 side where the developer is filled. For example, it is a case where projection parts 22g1, 22g3, 22h1, 22h3 as shown in FIG. 20 are provided.

つまり、現像剤収納ユニット等であれば、可撓性容器の開口が形成された面のうち現像剤を充填し封止した充填開口封止部が設けられている充填開口封止部側に、突起部を設けて用いる場合もある。この場合、突起部は、開口と充填開口封止部との間に設けられている。   That is, in the case of a developer storage unit or the like, on the side of the filling opening sealing portion provided with the filling opening sealing portion filled and sealed with the developer on the surface where the opening of the flexible container is formed, In some cases, a protrusion is provided. In this case, the protrusion is provided between the opening and the filling opening sealing portion.

また、物流等での衝撃で剥がれやすい部分は、開封時に最初に剥がれる部分であり、例えば、境界領域から開封方向の上流側に向かって延伸している突起部だけを設ける場合でも効果がある。   Further, the portion that is easily peeled off by an impact in physical distribution or the like is a portion that is peeled off first at the time of opening. For example, even when only a protrusion extending from the boundary region toward the upstream side in the opening direction is provided.

実施例3として、突起部22g、22hを用いない別の実施形態を述べる。実施例1では、「ロの字」形状の長辺方向(方向F)と短辺方向(方向E)の4本の接合部から延伸させた突起部について述べた。本実施例では、図21に示すように、「ロの字」形状の中央接合部22iに対して連続していない位置に孤立接合部23a、23b、23c、23dを設けている。実施例3では、孤立接合部は4箇所あるが、孤立接合部は4箇所である必要はなく、1箇所であってもかまわない。ただし、複数設けるほうが効果的である。現像剤収納容器26の変形が発生する部分について、開口を有する面34fの変形を抑えることができ、「ロの字」形状の中央接合部22iに変形による剥離力が直接掛かるのを抑えることができる。   As Example 3, another embodiment in which the protrusions 22g and 22h are not used will be described. In the first embodiment, the protrusions extended from the four joint portions in the long side direction (direction F) and the short side direction (direction E) of the “B” shape are described. In the present embodiment, as shown in FIG. 21, isolated joints 23a, 23b, 23c, and 23d are provided at positions that are not continuous with the central joint 22i having a "B" shape. In Example 3, there are four isolated joints, but the number of isolated joints is not necessarily four, and may be one. However, it is more effective to provide a plurality. For the portion where the developer container 26 is deformed, it is possible to suppress the deformation of the surface 34f having the opening, and to prevent the peeling force due to the deformation from being directly applied to the central joint portion 22i having the "B" shape. it can.

本実施例では、孤立接合部は、「ロの字」形状の接合部22iの角部から一番近い位置に設けられている。つまり、孤立接合部は、中央接合部の中で角部からの距離が一番短い位置に設けられている。また、孤立接合部は、中央接合部22iの外側に形成されている。また、図21からも分かるように、孤立接合部は、開口の露出の進む開封方向において接合部の中で最端に位置している。同様に、開封方向に対して垂直である垂直方向においても接合部の中で最端に位置している。   In the present embodiment, the isolated joint is provided at a position closest to the corner of the joint portion 22i having a “B” shape. That is, the isolated junction is provided at a position where the distance from the corner is the shortest among the central junctions. The isolated joint is formed outside the central joint 22i. Further, as can be seen from FIG. 21, the isolated joint is located at the end of the joint in the opening direction in which the opening is exposed. Similarly, in the vertical direction that is perpendicular to the opening direction, it is located at the end of the joint.

さらに、他の実施例と同様に、可撓性容器の開口が形成された面のうち現像剤を充填し封止した充填開口封止部が設けられている充填開口封止部側に、孤立接合部を設けて用いる場合もある。この場合、孤立接合部は、中央接合部と充填開口封止部との間に設けられている。   Further, as in the other embodiments, the surface of the flexible container where the opening is formed is isolated on the side of the filling opening sealing portion where the filling opening sealing portion filled with the developer and sealed is provided. In some cases, a junction is provided. In this case, the isolated joint portion is provided between the central joint portion and the filling opening sealing portion.

本実施形態によれば、製造時における可撓性容器の変形による封止部材の開封防止特性を向上させることができる。また、製造時だけでなく物流時の衝撃に対しても封止部材の開封防止特性を向上させることができる。   According to this embodiment, the opening prevention characteristic of the sealing member due to deformation of the flexible container at the time of manufacture can be improved. Further, the unsealing property of the sealing member can be improved not only at the time of manufacturing but also at the time of physical distribution.

(その他)
これまでの説明では、開口を封止している領域が「ロの字」形状の接合部であったため、「ロの字」形状の接合部22iに変形による剥離力が直接掛かるのを抑えることを効果として説明している。しかし、「ロの字」形状に限定されるものではなく、連続して閉じた領域22iで現像剤の排出を封止できている接合部であればよい。つまり、変形による剥離力が直接掛るのを抑える突起部や第二の接合部が設けられていればよく、当然「ロの字」形状以外のものでもよい。例えば、三角形状、楕円形状、菱形形状などがある。
(Other)
In the description so far, since the region sealing the opening has been the “B” -shaped joint, it is possible to prevent the peeling force due to deformation from being directly applied to the “B” -shaped joint 22i. Is explained as an effect. However, the shape is not limited to the “B” shape, and any joint may be used as long as the developer discharge can be sealed in the continuously closed region 22i. That is, it is only necessary to have a protrusion or a second joint that suppresses the direct application of a peeling force due to deformation, and it may naturally have a shape other than the “B” shape. For example, there are a triangular shape, an elliptical shape, a rhombus shape, and the like.

また、実施例1から3では、第一の接合部や第二の接合部が直線状であるが、蛇行している線、直線の一部が蛇行した線、ジグザグ状の線などの接合部でもよい。開口が円形の場合にその縁に沿った半円状の第一の接合部や第二の接合部でもよい。   In the first to third embodiments, the first joint and the second joint are linear, but the joint is a meandering line, a part of the straight line is meandering, a zigzag line, or the like. But you can. When the opening is circular, it may be a semicircular first joint or second joint along the edge.

さらに、実施例1から3では、組立時の可撓性容器の変形から剥離の観点から説明している。一方で、物流時の衝撃に対して封止部材防止特性を向上させることは望まれている。物流時の衝撃に対する観点からは、可撓性容器だけでなく、カートリッジに通常用いられるプラスチック等で製造されている可撓性でない容器に突起部や孤立接合部を設けても効果は得られる。よって、通常の容器に突起部や孤立接合部を設けた現像剤容器やその現像剤容器を収納した現像剤収納ユニットやプロセスカートリッジ等にも応用できる。さらに、現像剤容器が構成の一部となっている現像剤収納ユニットやプロセスカートリッジ等にも応用できる。   Further, in the first to third embodiments, the description is given from the viewpoint of peeling from the deformation of the flexible container at the time of assembly. On the other hand, it is desired to improve the sealing member prevention characteristic against an impact during distribution. From the viewpoint of impact at the time of physical distribution, an effect can be obtained by providing not only a flexible container but also a non-flexible container made of plastic or the like normally used for a cartridge, and a protrusion or an isolated joint. Therefore, the present invention can be applied to a developer container in which a protrusion or an isolated joint is provided in a normal container, a developer storage unit that stores the developer container, a process cartridge, and the like. Further, the present invention can be applied to a developer storage unit, a process cartridge, and the like in which a developer container is a part of the configuration.
