Description

本発明は、電子写真方式や静電記録方式を用いた画像形成装置、及びこれに用いられる現像剤補給容器に関し、特に、複写機、プリンタ、ＦＡＸ等の画像形成装置、及びこれに用いられる現像剤補給容器に関する。   The present invention relates to an image forming apparatus using an electrophotographic method or an electrostatic recording method, and a developer supply container used therefor, and in particular, an image forming apparatus such as a copying machine, a printer, or a fax, and a developing used therein Relating to the agent supply container.

従来、複写機等の電子写真式の画像形成装置には微粉末の現像剤が使用されている。このような画像形成装置では、画像形成に伴い消費されてしまう現像剤を、現像剤補給容器から補給する構成となっている。   Conventionally, fine powder developers have been used in electrophotographic image forming apparatuses such as copying machines. In such an image forming apparatus, the developer which is consumed along with the image formation is replenished from the developer replenishing container.

尚、現像剤補給については様々な方式が提案、実用されており、現像剤受入れ装置から駆動を与え、現像剤補給容器を回転させることで現像剤を補給する方式が多く採用されている。   In addition, various methods have been proposed and put into practical use for developer replenishment, and a system in which a developer is supplied by driving from a developer receiving device and rotating a developer replenishment container is often employed.

さらに、現像剤補給容器内の現像剤残量を知る手段の１つとして、現像剤補給容器の位相（回転数）を検知する方法がある。   Furthermore, there is a method of detecting the phase (the number of rotations) of the developer supply container as one of means for knowing the remaining amount of developer in the developer supply container.

こうした従来の現像剤補給容器の位相（回転数）を検知する方法としては、例えば、特許文献１のものがある。   As a method of detecting the phase (rotational speed) of such a conventional developer supply container, for example, there is the method of Patent Document 1.

特許文献１に記載の装置では、略円筒状の現像剤補給容器の外周に設けられた駆動受け部に画像形成装置本体から駆動力を与えることで現像剤補給容器が回転し、画像形成装置本体側に設けたエンコーダにより、回転数を検知する構成となっている。   In the apparatus described in Patent Document 1, the developer supply container is rotated by applying a driving force from the image forming apparatus main body to the drive receiving portion provided on the outer periphery of the substantially cylindrical developer supply container, and the image forming apparatus main body is rotated. The encoder provided on the side detects the number of rotations.

さらに特許文献１に記載の装置では、現像剤補給容器の回転時の摩擦を低減させるために現像剤受入れ装置側にコロが設けられている。このコロが略円筒状の現像剤補給容器と当接しながら回転することにより、現像剤補給容器は滑らかに回転することができる。従って、現像剤補給が適切に行われ、その間の現像剤補給容器の回転数を検知できる。   Furthermore, in the device described in Patent Document 1, a roller is provided on the developer receiving device side in order to reduce friction when the developer supply container rotates. The developer supply container can be smoothly rotated by rotating while the roller abuts on the substantially cylindrical developer supply container. Therefore, developer replenishment is appropriately performed, and the number of revolutions of the developer replenishment container can be detected.

特開２００５−１４８２３８号公報JP, 2005-148238, A

しかしながら、特許文献１に記載の装置では、略円筒状の現像剤補給容器の駆動受け部とコロが現像剤補給容器のスラスト方向に離れた位置にあり、さらに、現像剤補給容器のコロと当接する箇所には現像剤搬送用の螺旋溝が形成されている。そのため、現像剤補給時における現像剤補給容器の回転振れが発生する恐れがある。そして、現像剤補給容器の回転数の検知に限らず現像座補給容器の停止位置の検知をするような場合において、このような現像剤補給容器の挙動は小さくなる方が好ましい。   However, in the apparatus described in Patent Document 1, the drive receiving portion of the substantially cylindrical developer supply container and the roller are at positions separated in the thrust direction of the developer supply container, and the roller of the developer supply container A spiral groove for transporting the developer is formed at the contact portion. As a result, there is a risk that rotational shake of the developer supply container may occur at the time of developer supply. Then, in the case where the stop position of the developer supply container is detected as well as the rotation speed of the developer supply container, it is preferable that the behavior of such a developer supply container be smaller.

そこで、本発明の目的は、現像剤補給時における現像剤補給容器の回転振れを低減させ、現像剤補給容器の位相（回転）検知への影響を小さくする現像剤補給容器を提供することである。   Therefore, an object of the present invention is to provide a developer supply container which reduces the rotational runout of the developer supply container at the time of developer supply and reduces the influence on the phase (rotation) detection of the developer supply container. .

上記目的を達成するため、本発明は、駆動力を付与する付与部と、回転を検知する検知部と、を有する現像剤受入れ装置に挿入可能な現像剤補給容器おいて、現像剤を収容する回転可能な収容部と、前記収容部に収容された現像剤を現像剤補給容器から排出する排出口を有する現像剤排出部と、前記収容部に設けられ、前記収容部の現像剤を前記排出口に向かって搬送する現像剤搬送部と、前記付与部から駆動力を受ける回転可能なギア部と、前記ギア部が前記付与部から受けた駆動力により前記収容部と一体で回転する回転部材と、前記回転部材に設けられ、前記検知部が前記回転部材の回転を検知するための被検知部と、を有し、前記収容部は前記現像剤排出部に対して相対回転可能であって、現像剤補給容器の挿入方向において、前記回転部材は前記現像剤排出部よりも上流側にあり、前記被検知部は前記ギア部よりも下流側に配置され、前記被検知部の最大外径は前記ギア部の外径よりも小さいことを特徴とする。 In order to achieve the above object, the present invention accommodates a developer in a developer supply container that can be inserted into a developer receiving device having an application unit that applies a driving force and a detection unit that detects rotation. a rotatable housing portion, and the developer discharge part having a discharge port for discharging the developer accommodated in the accommodation portion from the developer supply container, is provided in the housing portion, the exhaust developer of the housing part A developer conveyance unit for conveying toward the outlet, a rotatable gear unit that receives a driving force from the application unit, and a rotating member that is integrally rotated with the storage unit by the driving force that the gear unit receives from the application unit And the detection unit provided on the rotation member, the detection unit detecting a rotation of the rotation member, and the storage unit is rotatable relative to the developer discharge unit. , in the insertion direction of the developer supply container, wherein Rolling member is in the upstream side of the developer discharging section, the detected portion is disposed downstream of the gear unit, said maximum outer diameter of the detection portion is smaller than the outer diameter of the gear portion It is characterized by

本発明によれば、駆動受け部と被検知部とが近い構成の場合に、駆動受け部で受ける駆動力の被検知部への影響を小さくすることができる。   According to the present invention, when the drive receiving portion and the detected portion are close to each other, the influence of the driving force received by the drive receiving portion on the detected portion can be reduced.

A copying machine (electrophotographic image forming apparatus employing an electrophotographic method as an example of an image forming apparatus equipped with a developer receiving device in which a developer supply container (so-called toner cartridge) is detachably (removably) mounted Will be described with reference to FIG.

図１において、１００は複写機本体（以下、「画像形成装置本体」もしくは「装置本体」という）である。また、１０１は原稿であり、原稿台ガラス１０２の上に置かれる。そして、原稿の画像情報に応じた光像を光学部１０３の複数のミラーＭとレンズＬｎにより、電子写真感光体１０４（以下、「感光体ドラム」という）上に結像させることにより静電潜像を形成する。この静電潜像は現像器２０１ｂにより現像剤としてのトナーを用いて可視化される。   In FIG. 1, reference numeral 100 denotes a copying machine main body (hereinafter referred to as “image forming apparatus main body” or “device main body”). An original 101 is placed on an original table glass 102. Then, an electrostatic latent image is formed by forming an optical image corresponding to the image information of the original on the electrophotographic photosensitive member 104 (hereinafter referred to as “photosensitive drum”) by the plurality of mirrors M and the lens Ln of the optical unit 103. Form an image. The electrostatic latent image is visualized by the developing device 201 b using toner as a developer.

１０５〜１０８は記録媒体（以下、「シート」ともいう）Ｓを収容するカセットである。これらカセット１０５〜１０８に積載されたシートＳのうち、図２に示す複写機の操作部１００ａから操作者（ユーザ）が入力した情報もしくは原稿１０１のシートサイズを基に最適なカセットが選択される。ここで記録媒体としては用紙に限定されずに、例えばＯＨＰシート等適宜使用、選択できる。   Reference numerals 105 to 108 denote cassettes for storing recording media (hereinafter also referred to as "sheets") S. Among the sheets S stacked in the cassettes 105 to 108, the optimum cassette is selected based on the information input by the operator (user) from the operation unit 100a of the copying machine shown in FIG. 2 or the sheet size of the original 101. . Here, the recording medium is not limited to a sheet, and can be appropriately used or selected, for example, an OHP sheet.

Then, after this, the end of the sheet S passes through the flapper 118, and is controlled by the flapper 118 at the timing when the sheet S is still nipped by the discharge roller 116 and is reversely rotated by the discharge roller 116. . Further, after this, the sheet is conveyed to the registration roller 110 via the re-feed conveyance units 119 and 120, and is discharged to the discharge tray 117 along the same path as in the case of single-sided copying.

また、多重コピーの場合には、シートＳは排出反転部１１５を通り、一度排出ローラ１１６により一部が装置外へ排出される。そして、この後、シートＳの終端がフラッパ１１８を通過し、排出ローラ１１６にまだ挟持されているタイミングでフラッパ１１８を制御すると共に排出ローラ１１６を逆回転させることにより、再度装置本体１００内へ搬送される。更にこの後、再給送搬送部１１９，１２０を経由してレジストローラ１１０まで搬送された後、片面コピーの場合と同様の経路をたどって排出トレイ１１７へ排出される。   Further, in the case of multiple copying, the sheet S passes through the discharge reversing unit 115, and a part of the sheet S is discharged to the outside of the apparatus by the discharge roller 116 once. Then, after that, the trailing end of the sheet S passes the flapper 118, and the flapper 118 is controlled at the timing when it is still pinched by the discharge roller 116, and the discharge roller 116 is reversely rotated. Be done. Thereafter, the sheet is conveyed to the registration roller 110 via the refeeding / conveying units 119 and 120, and is discharged to the discharge tray 117 along the same path as in the case of single-sided copying.

（現像剤補給容器）
現像剤補給容器１について図６を用いて説明する。図６は現像剤補給容器１の断面斜視図である。 (Developer supply container)
The developer supply container 1 will be described with reference to FIG. FIG. 6 is a cross-sectional perspective view of the developer supply container 1.

図６に示すように、現像剤補給容器１は、主に容器本体１Ａ、フランジ部４１、シャッタ５２、ポンプ部５４、往復部材５１、カバー５３から構成される。そして現像剤補給容器１は後述する現像剤補給手段により、現像剤補給容器１内の現像剤を現像剤ホッパ部２０１ａ（図５参照）へ補給する。以下に、現像剤補給容器１を構成する各要素について、詳細に説明する。   As shown in FIG. 6, the developer supply container 1 mainly includes a container main body 1A, a flange portion 41, a shutter 52, a pump portion 54, a reciprocating member 51, and a cover 53. Then, the developer replenishing container 1 replenishes the developer in the developer replenishing container 1 to the developer hopper portion 201a (see FIG. 5) by developer replenishing means described later. Hereinafter, each component of the developer supply container 1 will be described in detail.

（容器本体）
容器本体１Ａについて、図７を用いて説明する。図７は容器本体１Ａの斜視図である。 (Container body)
The container main body 1A will be described with reference to FIG. FIG. 7 is a perspective view of the container body 1A.

容器本体１Ａは、内部に現像剤を収容する現像剤収容部１Ａ２と、容器本体１Ａが軸Ｐに対してＲ方向に回転することによって現像剤収容部１Ａ２内の現像剤を矢印Ａ方向（図６）ヘ搬送する螺旋状の突起（現像剤搬送部）１Ａ１から構成される。   The container body 1A includes a developer accommodating portion 1A2 for accommodating the developer therein, and the developer in the developer accommodating portion 1A2 is rotated in the direction of arrow A by rotating the container body 1A in the R direction with respect to the axis P 6) Consisting of a helical protrusion (developer transport portion) 1A1 to be transported to the side.

容器本体１Ａは、現像剤受入れ装置２００の駆動ギア２５より回転駆動力を受ける駆動受け部１Ａ５と、前記駆動受け部１Ａ５に入力する回転駆動力により回転する前記収容部１Ａ２の位相を検知するための位相検知部１Ａ６を有している。さらに容器本体１Ａは、前記収容部１Ａ２が回転する際、前記位相検知部１Ａ６と前記駆動受け部１Ａ５の回転振れを抑制するための回転振れ規制部１Ａ４を有している。さらに本実施例１の容器本体１Ａは、後述する実施例２の容器に対し、カム溝１Ａ３が設けられている点が異なる。本実施例１では、回転振れ規制部１Ａ４、駆動受け部１Ａ５、位相検知部１Ａ６が、容器本体１Ａと一体的に形成されている。図６（ｂ）に項の構成を示す。本実施例では、プラスチック等からなる一つの樹脂材料（本実施例では駆動受け部品）に位相検知部１Ａ６と駆動受け部１Ａ５の回転振れを抑制するための回転振れ規制部１Ａ４が設けられている。そして、駆動受け部品の端部に設けられている駆動伝達部1A7が現像剤収容部１Ａ２と接続する。駆動伝達部１Ａ７と現像剤収容部１Ａ２とが一体で回転することで、駆動受け部1A5が受けた駆動力を現像剤収容部１Ａ２に伝達する。その結果、トナーを搬送する搬送部が回転可能となっている。   The container main body 1A detects a phase of the drive receiving portion 1A5 receiving the rotational driving force from the driving gear 25 of the developer receiving device 200, and the storage portion 1A2 rotated by the rotational driving force input to the drive receiving portion 1A5. Phase detection unit 1A6 of FIG. Furthermore, the container body 1A has a rotational runout control unit 1A4 for suppressing rotational runout of the phase detection unit 1A6 and the drive receiving unit 1A5 when the storage unit 1A2 rotates. Furthermore, the container main body 1A of the first embodiment is different from the container of the second embodiment described later in that a cam groove 1A3 is provided. In the first embodiment, the rotational shake regulation unit 1A4, the drive receiving unit 1A5, and the phase detection unit 1A6 are integrally formed with the container body 1A. The configuration of the item is shown in FIG. In the present embodiment, a rotation shake restricting portion 1A4 for suppressing the rotation shake of the phase detection portion 1A6 and the drive receiving portion 1A5 is provided in one resin material (a drive receiving component in the present embodiment) made of plastic or the like. . Then, the drive transmission portion 1A7 provided at the end of the drive receiving part is connected to the developer storage portion 1A2. The drive transmitting portion 1A7 and the developer accommodating portion 1A2 integrally rotate to transmit the driving force received by the drive receiving portion 1A5 to the developer accommodating portion 1A2. As a result, the transport unit that transports the toner is rotatable.

尚、本実施例１では、回転振れ規制部１Ａ４と駆動受け部１Ａ５と位相検知部１Ａ６が容器本体１Ａとが一体的に一つの部品に形成されている構成（図６（ｂ））を例示したが、これに限定されるものではない。例えば、カム溝１Ａ３と回転振れ規制部１Ａ４と駆動受け部１Ａ５と位相検知部１Ａ６とが一体に形成され、容器本体１Ａに一体的に取り付ける構成等であってもよい。   In the first embodiment, a configuration (FIG. 6B) is exemplified in which the rotational shake regulation unit 1A4, the drive receiving unit 1A5, and the phase detection unit 1A6 are integrally formed with the container body 1A. However, it is not limited to this. For example, the cam groove 1A3, the rotational runout restricting portion 1A4, the drive receiving portion 1A5, and the phase detecting portion 1A6 may be integrally formed and integrally attached to the container main body 1A.

また、前記収容部１Ａ２は、容器本体１Ａだけではなく、容器本体１Ａと後述するフランジ部４１（図８参照）とポンプ部５４（図１１参照）の内部スペースを合わせたものとなる。   Further, not only the container body 1A but also the container space 1A, and the internal space of the flange portion 41 (see FIG. 8) described later and the pump portion 54 (see FIG. 11) are combined.

また、本実施例１では、回転振れ規制部１Ａ４に対して位相検知部１Ａ６の形状を凹形状としたが、回転振れ規制部１Ａ４に対して位相検知部１Ａ６の形状を凸形状にしてもかまわない。   In the first embodiment, the phase detection unit 1A6 has a concave shape with respect to the rotational shake restriction unit 1A4, but the phase detection unit 1A6 may have a convex shape with respect to the rotational shake restriction unit 1A4. Absent.

実施例１では、現像剤補給容器１がＲ方向に回転して現像剤を補給する際（図６）、駆動受け部１Ａ５と位相検知部１Ａ６の双方のラジアル方向のガタ防止効果の向上を目的として、回転振れ規制部１Ａ４の真円度を０．０５とした。回転振れ規制部１Ａ４は真円に近いほど、より高いラジアル方向のガタ防止効果が期待できるが、必要以上の幾何公差を設けるとコストアップにつながるため、真円度を０．０５とした。このように回転振れ規制部は円筒部の形状となっている。   In the first embodiment, when the developer supply container 1 rotates in the R direction to supply the developer (FIG. 6), the purpose is to improve the effect of preventing the radial direction of both the drive receiving portion 1A5 and the phase detection portion 1A6. The roundness of the rotation control unit 1A4 is set to 0.05. As the rotational runout restricting portion 1A4 is closer to a true circle, higher radial rattle prevention effect can be expected, but providing a geometric tolerance more than necessary leads to an increase in cost, so the roundness is set to 0.05. Thus, the rotational runout regulating portion has a cylindrical shape.

このような構成とすることで、現像剤補給時に現像剤補給容器１が図６の矢印Ｒ方向に回転する際、真円に近い形状の回転振れ規制部１Ａ４とボトル受けローラ（回転部材）２３が当接することで位相検知部１Ａ６と駆動受け部１Ａ５の双方の回転振れを抑制できる。このように、回転振れ規制部は回転部材と当接する当接面としての機能を有する。その結果、駆動伝達と位相検知の双方の精度向上が期待できる。さらに、現像剤補給容器１の回転による振動も低減できるため、画質の向上が期待できる。   With such a configuration, when developer supply container 1 is rotated in the direction of arrow R in FIG. 6 at the time of developer supply, rotation runout regulating portion 1A4 having a shape close to a perfect circle and a bottle receiving roller (rotating member) 23 As a result, the rotational shake of both the phase detection unit 1A6 and the drive receiving unit 1A5 can be suppressed. Thus, the rotational runout restricting portion has a function as an abutting surface that abuts on the rotating member. As a result, it is expected to improve the accuracy of both drive transmission and phase detection. Further, since the vibration due to the rotation of the developer supply container 1 can also be reduced, improvement in image quality can be expected.

また、駆動受け部品は駆動受け部１Ａ５及び位相検知部１Ａ６を回転振れ規制部１Ａ４に隣接して配置した構成である。このような構成とすることで、駆動受け部１Ａ５と位相検知部１Ａとを離れた位置に配置した構成に比べて、位相検知部１Ａ６と駆動受け部１Ａ５の双方の回転振れをより抑制できる。その結果、駆動伝達と位相検知の双方の精度向上や、画質の向上がより期待できる。   Further, the drive receiving component is configured such that the drive receiving portion 1A5 and the phase detection portion 1A6 are disposed adjacent to the rotational shake restricting portion 1A4. With such a configuration, rotational runout of both phase detection unit 1A6 and drive reception unit 1A5 can be further suppressed, as compared to a configuration in which drive reception unit 1A5 and phase detection unit 1A are disposed at a distance. As a result, it is possible to further expect improvement in accuracy of both drive transmission and phase detection and improvement in image quality.

（バッフル部材）
バッフル部材４０について図６を用いて説明する。図６は実施例１における現像剤補給容器１の部分断面斜視図である。 (Baffle member)
The baffle member 40 will be described with reference to FIG. FIG. 6 is a partial cross-sectional perspective view of the developer supply container 1 according to the first embodiment.

実施例１のバッフル部材４０は、最終的に現像剤を搬送する箇所が後述する実施例２とは異なる。具体的には、最終的に現像剤はバッフル部材４０の回転に伴って、傾斜突起４０ａを滑り落ちるように貯留部４１ｆ（図９（ｂ））へ搬送される点が実施例２とは異なる。   The baffle member 40 according to the first embodiment is different from the baffle member 40 according to the second embodiment in which the developer is finally transported. Specifically, the second embodiment is different from the second embodiment in that the developer is finally transported to the storage portion 41f (FIG. 9B) so as to slide down the inclined projection 40a as the baffle member 40 rotates.

ポンプ部５４は、「山折り」部と「谷折り」部が周期的に形成された蛇腹状の伸縮部５４ａが設けられている。その折り目を基点として、伸縮部５４ａは折り畳まれたり、伸びたりすることができる。   The pump portion 54 is provided with a bellows-like stretchable portion 54 a in which a “mountain fold” portion and a “valley fold” portion are periodically formed. The stretchable portion 54a can be folded or stretched based on the fold.

また、実施例１ではポンプ部５４の材料としてはポリプロピレン樹脂（以下、ＰＰと略す）を採用したが、これに限定されるものではない。ポンプ部５４の材料に関しては、伸縮機能を発揮し容積変化によって現像剤収容部１Ａ２（図７）の内圧を変化させることができる前提の材料であれば何でもよい。例えば、ＡＢＳ（アクリロニトリル・ブタジエン・スチレン共重合体）、ポリスチレン、ポリエステル、ポリエチレン等を薄肉で形成したものでも構わない。また、ゴムやその他の伸縮性材料などを使用することも可能である。さらに、ポンプ部５４の役割は現像剤収容部１Ａ２（図７）の内圧を変化させることであるため、ポンプの代わりにピストンを使用することも可能である。   Moreover, although polypropylene resin (it abbreviates to PP hereafter) was adopted as a material of pump part 54 in Example 1, it is not limited to this. With regard to the material of the pump portion 54, any material may be used as long as it can expand and contract and change the internal pressure of the developer storage portion 1A2 (FIG. 7) by volume change. For example, thin films of ABS (acrylonitrile-butadiene-styrene copolymer), polystyrene, polyester, polyethylene or the like may be used. It is also possible to use rubber or other stretchable material. Furthermore, since the role of the pump unit 54 is to change the internal pressure of the developer storage unit 1A2 (FIG. 7), it is also possible to use a piston instead of the pump.

（往復部材）
次に、図１２を用いて往復部材５１について説明する。図１２（ａ）、図１２（ｂ）は往復部材５１の斜視図を示している。 (Reciprocating member)
Next, the reciprocating member 51 will be described with reference to FIG. 12 (a) and 12 (b) show perspective views of the reciprocating member 51. FIG.

往復部材５１は前述したポンプ部５４の容積を変化させるために、ポンプ部５４に設けられた往復部材係合部５４ｃ（図１１）に係合するポンプ部係合部５１ａを備えている。さらに往復部材５１は組み立てられた際に、前述したカム溝１Ａ３（図７）に嵌め込まれる係合突起５１ｂを備えている。係合突起５１ｂはポンプ部係合部５１ａ近傍より延在するアーム５１ｃの先端部に設けられている。また、往復部材５１は、後述するカバー５３の往復部材保持部５３ｂ（図１３（ｂ））によって矢印Ａ、Ｂ方向（図６）にのみスライド可能に保持される。したがって、駆動受け部１Ａ５（図７）が駆動ギア２５（図５）から回転駆動力を受け、容器本体１Ａが回転すると、カム溝１Ａ３も容器本体１Ａに同期して回転し、カム溝１Ａ３（図７）に嵌め込まれた係合突起５１ｂのカム作用とカバー５３の往復部材保持部５３ｂ（図１４（ｂ））の作用により、往復部材５１は矢印Ａ、Ｂ方向へ往復運動する（図６）。その往復運動に同期して、ポンプ部５４が伸縮運動をする。すなわち、往復部材５１は、カム溝１Ａ３とともに、駆動受け部１Ａ５に入力する回転駆動力をポンプ部５４を動作させる力へ変換する。   The reciprocating member 51 is provided with a pump portion engaging portion 51a engaged with a reciprocating member engaging portion 54c (FIG. 11) provided in the pump portion 54 in order to change the volume of the pump portion 54 described above. Furthermore, the reciprocating member 51 is provided with an engagement protrusion 51b which is fitted into the above-mentioned cam groove 1A3 (FIG. 7) when assembled. The engagement protrusion 51b is provided at the tip of the arm 51c extending from the vicinity of the pump portion engagement portion 51a. Further, the reciprocation member 51 is held slidably only in the directions of arrows A and B (FIG. 6) by a reciprocation member holding portion 53b (FIG. 13B) of a cover 53 described later. Therefore, when the drive receiving portion 1A5 (FIG. 7) receives rotational driving force from the drive gear 25 (FIG. 5) and the container body 1A rotates, the cam groove 1A3 also rotates in synchronization with the container body 1A. The reciprocation member 51 reciprocates in the directions of arrows A and B (FIG. 6) by the cam action of the engagement projection 51b fitted in FIG. 7) and the action of the reciprocation member holding portion 53b (FIG. 14b) of the cover 53. ). In synchronization with the reciprocation, the pump portion 54 stretches and contracts. That is, the reciprocating member 51, together with the cam groove 1A3, converts the rotational drive force input to the drive receiving portion 1A5 into a force for operating the pump portion 54.

（カバー）
次に図１３を用いてカバー５３について説明する。図１３（ａ）、図１３（ｂ）はカバー５３の斜視図を示している。 (cover)
Next, the cover 53 will be described with reference to FIG. 13 (a) and 13 (b) show perspective views of the cover 53. FIG.

上述したように、カバー５３は、ユーザーが現像剤補給容器１に触れて予期せぬケガが発生するのを防止する目的と、往復部材５１やポンプ部５４の保護を目的として、図６のように設けられている。詳しくは、カバー５３は、フランジ部４１、ポンプ部５４、往復部材５１の全体を覆うようにフランジ部４１と一体的に設けられている。   As described above, as shown in FIG. 6, the cover 53 is for the purpose of preventing the user from touching the developer supply container 1 and causing an unexpected injury, and for the purpose of protecting the reciprocating member 51 and the pump portion 54. Provided in Specifically, the cover 53 is provided integrally with the flange portion 41 so as to cover the whole of the flange portion 41, the pump portion 54, and the reciprocating member 51.

また、カバー５３には、現像剤受入れ装置２００が備える挿入ガイド２００ｅ（図４）と係合することで、現像剤補給容器１を現像剤受入れ装置２００に挿入するのをサポートするガイド溝５３ａが設けられている。さらに、カバー５３には、軸Ｐ（図６）に対して往復部材５１の回転変位を規制するための往復部材保持部５３ｂが設けられている。   Further, the cover 53 has a guide groove 53a for supporting insertion of the developer supply container 1 into the developer receiving device 200 by engaging with the insertion guide 200e (FIG. 4) included in the developer receiving device 200. It is provided. Further, the cover 53 is provided with a reciprocating member holding portion 53b for restricting the rotational displacement of the reciprocating member 51 with respect to the axis P (FIG. 6).

そして、カバー５３には、現像剤補給容器１を現像剤受入れ装置２００に挿入する際、現像剤受入れ装置２００のカバー突き当て部２００ｇ（図５）と当接することで現像剤補給容器１の装着を完了させるための現像剤受入れ装置突き当て部５３ｃが設けられている。現像剤補給容器１を現像剤受入れ装置２００に挿脱着する詳しい方法は後述する。   When the developer supply container 1 is inserted into the developer receiving device 200, the cover 53 abuts on the cover abutting portion 200g (FIG. 5) of the developer receiving device 200 so that the developer supply container 1 is mounted. And a developer receiving device abutting portion 53c for completing the process. The detailed method of inserting and removing the developer supply container 1 into and from the developer receiving apparatus 200 will be described later.

（現像剤排出原理）
次に、現像剤排出原理について、図６を用いて説明する。軸Ｐを中心とした、現像剤補給容器１の回転（矢印Ｒ方向）によって容器本体１Ａに形成された螺旋状の突起１Ａ１が現像剤を容器本体１Ａの上流側から下流側（矢印Ａ方向）へ搬送する。そして、螺旋状の突起１Ａ１によって搬送された現像剤はやがてバッフル部材４０に達する。次に現像剤補給容器１と一体的に回転するバッフル部材４０で掻き揚げられた現像剤がバッフル部材４０の表面上を滑り落ち、傾斜突起４０ａによってフランジ部４１の貯留部４１ｆへ搬送される。この動作を繰り返すことによって、現像剤補給容器１内部の現像剤は順次、撹拌・搬送されてフランジ部４１の貯留部４１ｆ（図９（ｂ））へ貯留される。 (Developer discharge principle)
Next, the developer discharging principle will be described with reference to FIG. A helical protrusion 1A1 formed on the container body 1A by rotation (direction of arrow R) of the developer supply container 1 around the axis P moves developer from the upstream side to the downstream side (direction of arrow A) of the container body 1A. Transport to Then, the developer conveyed by the helical protrusion 1A1 reaches the baffle member 40 soon. Next, the developer scraped up by the baffle member 40 which rotates integrally with the developer supply container 1 slides down on the surface of the baffle member 40 and is transported to the storage portion 41f of the flange portion 41 by the inclined projection 40a. By repeating this operation, the developer in the developer supply container 1 is sequentially stirred and transported, and is stored in the storage portion 41 f of the flange portion 41 (FIG. 9B).

そして、上述したように、往復部材５１の往復運動と同期して、ポンプ部５４は伸縮運動をする。詳しく説明すると、ポンプ部５４を縮める際には、現像剤補給容器１内が加圧状態となり、その圧力に押し出される形で貯留部４１ｆ（図９（ｂ））に貯留された現像剤が排出口１ａ（図１０（ａ））から排出される。またポンプ部５４を伸ばす際には、現像剤補給容器１内が減圧状態になり、外部から排出口１ａ（図１０（ａ））を介してエアが取り込まれる。この取り込まれたエアにより排出口１ａ（図１０（ａ））や貯留部４１ｆ（図９（ｂ））付近の現像剤が解れ、次の排出がスムーズに行われるようになっている。以上のようにポンプ部５４が伸縮運動を繰り返し行うことで現像剤の排出が行われる。   Then, as described above, in synchronization with the reciprocation of the reciprocating member 51, the pump portion 54 performs the telescopic movement. More specifically, when the pump portion 54 is contracted, the inside of the developer supply container 1 is pressurized, and the developer stored in the storage portion 41f (FIG. 9B) is discharged by being pushed out by the pressure. It is discharged from the outlet 1a (FIG. 10 (a)). When the pump portion 54 is extended, the inside of the developer supply container 1 is decompressed, and air is taken in from the outside through the discharge port 1a (FIG. 10A). The developer taken in the vicinity of the discharge port 1a (FIG. 10A) and the storage section 41f (FIG. 9B) is loosened by the taken-in air, and the next discharge is smoothly performed. As described above, the developer is discharged by the pump unit 54 repeatedly performing the extension and contraction motion.

（現像剤補給容器の挿入動作）
次に実施例１における現像剤補給容器の挿入動作（装着動作）について図１４（ａ）〜（ｄ）を用いて説明する。 (Insertion operation of developer supply container)
Next, the insertion operation (mounting operation) of the developer supply container in Embodiment 1 will be described using FIGS. 14 (a) to 14 (d).

図１４（ａ）には、現像剤補給容器１を現像剤受入れ装置２００に挿入させる途中の状態が示されている。   FIG. 14A shows a state in which the developer supply container 1 is being inserted into the developer receiving device 200.

図１４（ｂ）には、現像剤補給容器１の挿入が更に進み、シャッタ５２の先端部に設けたストッパ部５２ｂ（図１０（ａ））と現像剤受入れ装置２００に設けられたシャッタストッパ部２００ａ（図４）に係止された状態が示されている。   In FIG. 14B, the insertion of the developer supply container 1 further proceeds, and the stopper 52b (FIG. 10A) provided at the tip of the shutter 52 and the shutter stopper provided in the developer receiving device 200 A locked state is shown at 200a (FIG. 4).

図１４（ｃ）は、現像剤補給容器１の現像剤受入れ装置突き当て部５３ｃ（図１３（ａ））をカバー突き当て部２００ｇ（図４）まで突き当てることによって現像剤補給容器１の装着が完了した状態を示している。   FIG. 14C shows the mounting of the developer supply container 1 by abutting the developer receiving device abutting portion 53c (FIG. 13A) of the developer supply container 1 to the cover abutting portion 200g (FIG. 4). Indicates a completed state.

図１４（ｄ）は図１４（ｂ）の部分Ｇ−Ｇ断面図である。   FIG. 14D is a sectional view taken along line G-G in FIG.

まず、現像剤補給容器１を現像剤受入れ装置２００に矢印Ａ方向へ装着し始めると、フランジユニット部６０は現像剤受入れ装置２００に対して軸Ｐ（図５）に対して回転が不可となるように保持される。この時点では、シール穴４１ｊ（図８（ｂ））はシャッタ５２の現像剤封止部５２ａ（図１０（ｂ））によって封止された状態にある。   First, when the developer supply container 1 starts to be mounted on the developer receiving device 200 in the direction of arrow A, the flange unit portion 60 can not rotate with respect to the axis P (FIG. 5) with respect to the developer receiving device 200. To be held. At this time, the seal hole 41j (FIG. 8B) is sealed by the developer sealing portion 52a (FIG. 10B) of the shutter 52.

そのまま現像剤補給容器１を矢印Ａ方向に挿入すると、シャッタ５２はシャッタストッパ部２００ａ（図４）とストッパ部５２ｂ（図１０（ａ））との係止により、シャッタ５２はこれ以上矢印Ａ方向に変位不可となり、その状態で現像剤補給容器１のみが矢印Ａ方向へ動くため、シャッタ５２は現像剤補給容器１に対して相対的に矢印Ｂ方向にスライドしていく（図１４（ｂ）、図１４（ｄ））。   When the developer supply container 1 is inserted as it is in the direction of arrow A, the shutter 52 is locked between the shutter stopper portion 200a (FIG. 4) and the stopper portion 52b (FIG. 10 (a)). Since only the developer supply container 1 moves in the direction of arrow A in that state, the shutter 52 slides relative to the developer supply container 1 in the direction of arrow B (FIG. 14 (b)). , FIG.14 (d).

さらに現像剤補給容器１を矢印Ａ方向にスライドさせ、現像剤補給容器１の現像剤受入れ装置突き当て部５３ｃをカバー突き当て部２００ｇまで突き当てることによって、現像剤補給容器１の装着が完了する（図１４（ｃ））。このとき、フランジ部４１に設けているシール穴４１ｊ（図８（ｂ））がシャッタ５２に設けられている排出口１ａ（図１０（ａ））と重なることで連通し、現像剤補給が可能となる。   Furthermore, the developer supply container 1 is slid in the direction of arrow A, and the developer receiving device abutting portion 53c of the developer supply container 1 is abutted against the cover abutting portion 200g, whereby the mounting of the developer supply container 1 is completed. (FIG. 14 (c)). At this time, the seal hole 41j (FIG. 8 (b)) provided in the flange portion 41 communicates with the discharge port 1a (FIG. 10 (a)) provided in the shutter 52 so that developer can be replenished. It becomes.

この状態での駆動モータ（図５）を駆動させると、回転駆動力は、駆動ギア２５から駆動受け部１Ａ５へと伝達され、容器本体１Ａが回転し、現像剤を搬送、排出する構成になっている。   When the drive motor (FIG. 5) in this state is driven, the rotational drive force is transmitted from the drive gear 25 to the drive receiving portion 1A5, and the container body 1A is rotated to transport and discharge the developer. ing.

また、図５、図１４（ｃ）において、現像剤補給容器１は現像剤受入れ装置２００に設けられたボトル受けローラ２３と回転振れ規制部１Ａ４の当接により回転可能に支持されているため、わずかな駆動トルクでもスムーズに回転することが可能である。尚、ボトル受けローラ２３は現像剤受入れ装置２００に回転自在に設けてある。上述したように、現像剤補給容器１の内部に収容されている現像剤が排出口１ａから順次排出されることで、現像剤は現像剤ホッパ部２０１ａ（図１４）に一時的に貯留され、さらにスクリュー部材２７（図１４）により現像器２０１ｂ（図１）へ搬送され、現像剤補給が行われる。以上が、現像剤補給容器１の挿入動作である。   Further, in FIG. 5 and FIG. 14C, the developer supply container 1 is rotatably supported by the contact of the bottle receiving roller 23 provided in the developer receiving device 200 and the rotational runout regulating portion 1A4. Even small driving torque can rotate smoothly. The bottle receiving roller 23 is rotatably provided in the developer receiving device 200. As described above, the developer contained in the developer supply container 1 is sequentially discharged from the discharge port 1a, whereby the developer is temporarily stored in the developer hopper portion 201a (FIG. 14). Further, the developer is transported to the developing device 201b (FIG. 1) by the screw member 27 (FIG. 14), and the developer is replenished. The above is the insertion operation of the developer supply container 1.

（現像剤補給容器の交換動作）
次に、現像剤補給容器１の交換動作について図１４（ａ）〜（ｄ）を用いて説明する。画像形成のプロセスに伴い、現像剤補給容器１内の現像剤が略全量消費されると、現像剤受入れ装置２００に設けられた現像剤補給容器空検知手段（不図示）によって現像剤補給容器１内の現像剤が無くなったことが検知され、その旨が液晶等の表示手段１００ｂ（図３）によりユーザーに知らされる。 (Developer supply container replacement operation)
Next, the replacing operation of the developer supply container 1 will be described with reference to FIGS. 14 (a) to 14 (d). When the entire amount of the developer in the developer supply container 1 is consumed along with the process of image formation, the developer supply container 1 is provided by the developer supply container empty detection means (not shown) provided in the developer receiving device 200. It is detected that the developer inside is exhausted, and the user is notified of that by the display means 100b (FIG. 3) such as liquid crystal.

現像剤補給容器１の交換はユーザー自身が行い、その手順は以下の通りである。   The replacement of the developer supply container 1 is performed by the user, and the procedure is as follows.

まず、閉じられた状態の交換用前カバー１５を図３の位置まで開く。次にユーザーが図１４（ｃ）の状態の現像剤補給容器１を矢印Ｂ方向にスライドさせる。このとき、フランジ部４１に設けているシール穴４１ｊ（図８（ｂ））がシャッタ５２に設けられている排出口１ａ（図１０（ａ））と重なることで連通しており、現像剤補給が可能な状態である。   First, the replacement front cover 15 in the closed state is opened to the position shown in FIG. Next, the user slides the developer supply container 1 in the state of FIG. At this time, the seal hole 41j (FIG. 8 (b)) provided in the flange portion 41 communicates with the discharge port 1a (FIG. 10 (a)) provided in the shutter 52 to communicate with the developer. Is possible.

そのまま現像剤補給容器１を矢印Ｂ方向にスライドさせると、やがてフランジ部４１のシャッタ押出しリブ４１ｋ（図９（ｄ）、図１４（ｄ））がシャッタ５２のストッパ部５２ｂ（図１０（ａ））を矢印Ｂ方向（図１５）へ押し始める。   When the developer supply container 1 is slid as it is in the direction of the arrow B, the shutter push-out rib 41k (FIG. 9 (d), FIG. 14 (d)) of the flange portion 41 soon becomes the stopper 52b (FIG. 10 (a)). )) In the direction of arrow B (FIG. 15).

さらに現像剤補給容器１を矢印Ｂ方向へスライドさせていくと、現像剤受入れ装置２００のシャッタストッパ部２００ｂ（図４）とシャッタ５２のストッパ部５２ｃ（図１０（ａ））の係合により支持部５２ｄ（図１０（ａ））を基点にシャッタストッパ部５２ｂ，５２ｃは矢印Ｈ方向（図１４（ｄ））に撓み、シャッタ５２は矢印Ｂ方向へ進む（図１４（ｂ）、図１４（ｄ））。   When the developer supply container 1 is further slid in the direction of arrow B, the developer is supported by the engagement of the shutter stopper portion 200b (FIG. 4) of the developer receiving device 200 and the stopper portion 52c (FIG. 10A) of the shutter 52. The shutter stoppers 52b and 52c are bent in the direction of arrow H (FIG. 14 (d)) with respect to the portion 52d (FIG. 10 (a)), and the shutter 52 proceeds in the direction of arrow B (FIG. 14 (b), FIG. d)).

さらに現像剤補給容器１を矢印Ｂ方向にスライドすると、シャッタの支持部５２ｄ（図１０）は自らの弾性力によって復帰し、挿入ガイド２００ｅによるシャッタストッパ部５２ｂとストッパ部５２ｃの係止が解除され、フランジ部４１に設けているシール穴４１ｊ（図８（ｂ））とシャッタ５２に設けられている現像剤封止部５２ａ（図１０（ｂ））が重なることでシール穴４１ｊ（図８（ｂ））が封鎖される（図１４（ａ））。   When the developer supply container 1 is further slid in the direction of arrow B, the support portion 52d (FIG. 10) of the shutter returns due to its own elastic force, and the engagement between the shutter stopper 52b and the stopper 52c by the insertion guide 200e is released. The seal hole 41j (FIG. 8 (b)) provided in the flange portion 41 and the developer sealing portion 52a (FIG. 10 (b)) provided in the shutter 52 overlap with each other, thereby forming the seal hole 41j (FIG. b) is closed (Fig. 14 (a)).

次にユーザーは、空の現像剤補給容器１を図１４（ａ）に示す矢印Ｂ方向に引き出し、現像剤受入れ装置２００から取り出す。この後、ユーザーは新しい現像剤補給容器１を現像剤受入れ装置２００に矢印Ａ方向へ挿入した後（図１４（ｃ））、交換用前カバー１５（図３）を閉じる。そして、上述したようにシール穴４１ｊ（図８（ｂ））とシャッタ５２の排出口１ａ（図１０（ａ））が重なることで連通し、現像剤補給が可能な状態となる。以上が、現像剤補給容器の交換動作である。   Next, the user pulls out the empty developer supply container 1 in the direction of arrow B shown in FIG. Thereafter, the user inserts a new developer supply container 1 into the developer receiving apparatus 200 in the direction of arrow A (FIG. 14 (c)), and then closes the replacement front cover 15 (FIG. 3). Then, as described above, the seal hole 41j (FIG. 8B) and the discharge port 1a of the shutter 52 overlap (FIG. 10A) communicate with each other, and the developer can be replenished. The above is the replacement operation of the developer supply container.

〔現像剤受入れ装置による現像剤補給制御〕
次に、実施形態１の現像剤受入れ装置２００による現像剤補給制御について、図１５、図１６を用いて説明する。図１５は制御装置６００の機能構成を示すブロック図であり、図１６は補給動作の流れを説明するフローチャートである。 [Developer supply control by developer receiving device]
Next, developer replenishment control by the developer receiving device 200 of Embodiment 1 will be described with reference to FIGS. FIG. 15 is a block diagram showing a functional configuration of the control device 600, and FIG. 16 is a flow chart for explaining the flow of the replenishment operation.

実施例１では、軸Ｐを中心に回転する位相検知部１Ａ６（図２３）に位相検知フラグ６２を当接させ、位相検知フラグ６２が位相検知センサ６１を通過することで、現像剤供給容器１の位相（回転数）を検知している。位相検知センサ６１の出力に応じて制御装置６００が駆動モータ５００を作動／非作動の制御を行うことにより、現像剤補給容器１内の現像剤を定量的に現像剤ホッパ部２０１ａ内に排出（補給）している。   In the first embodiment, the phase detection flag 62 is brought into contact with the phase detection unit 1A6 (FIG. 23) rotating about the axis P, and the phase detection flag 62 passes through the phase detection sensor 61. Phase (rotational speed) is detected. The control device 600 controls the drive motor 500 to be activated / deactivated according to the output of the phase detection sensor 61, thereby quantitatively discharging the developer in the developer supply container 1 into the developer hopper portion 201a. Supply).

また、実施例１では、現像剤ホッパ部２０１ａ内に一時的に貯留される現像剤の量（現像剤面の高さ）を制限している。そこで、現像剤ホッパ部２０１ａ内に収容されている現像剤の量を検知する現像剤センサ２４ｋ（不図示）を設けている。そして、その現像剤センサ２４ｋの出力に応じて制御装置６００が駆動モータ５００を作動／非作動の制御を行うことにより、現像剤ホッパ部２０１ａ内に一定量以上の現像剤が収容されないように構成している。   Further, in Example 1, the amount of developer (height of developer surface) temporarily stored in the developer hopper portion 201a is limited. Therefore, a developer sensor 24k (not shown) for detecting the amount of developer contained in the developer hopper portion 201a is provided. Then, the control device 600 controls the drive motor 500 to be activated / deactivated according to the output of the developer sensor 24k, so that the developer hopper portion 201a is prevented from containing a predetermined amount or more of the developer. doing.

その制御フローについて説明する。まず図１６に示すように、現像剤センサ２４ｋが現像剤ホッパ部２０１ａ内の現像剤残量をチェックする（Ｓ１００）。そして、現像剤センサ２４ｋにより検出された現像剤収容量が所定未満であると判断された場合、つまり現像剤センサ２４ｋにより現像剤が検出されなかった場合、駆動モータ５００を駆動し、現像剤の補給を実行する（Ｓ１０１）。   The control flow will be described. First, as shown in FIG. 16, the developer sensor 24k checks the remaining amount of developer in the developer hopper portion 201a (S100). When it is determined that the developer storage amount detected by the developer sensor 24k is less than a predetermined amount, that is, when the developer is not detected by the developer sensor 24k, the drive motor 500 is driven to Supply is performed (S101).

次に、位相検知フラグ６２が位相検知センサ６１を通過したかをチェックする（Ｓ１０２）。位相検知フラグ６２が位相検知センサ６１を通過していない場合、現像剤の補給は継続される（Ｓ１０３）。一方、位相検知フラグ６２が位相検知センサ６１を通過した場合、駆動モータ５００の駆動をオフし（Ｓ１０５）、再度現像剤ホッパ部２０１ａ内の現像剤残量をチェックする（Ｓ１００）。このように、現像剤補給容器１の位相（回転）を検知して現像剤の補給動作を作動／非作動することで、定量的に現像剤補給を実行できる。更に、現像剤補給容器１の位相（回転）を検知することで、現像剤補給容器１内の現像剤残量をある程度予測することもできる。   Next, it is checked whether the phase detection flag 62 has passed the phase detection sensor 61 (S102). If the phase detection flag 62 has not passed through the phase detection sensor 61, the replenishment of the developer is continued (S103). On the other hand, when the phase detection flag 62 passes the phase detection sensor 61, the drive of the drive motor 500 is turned off (S105), and the remaining amount of developer in the developer hopper portion 201a is checked again (S100). Thus, developer replenishment can be quantitatively performed by detecting the phase (rotation) of the developer replenishment container 1 and activating / deactivating the developer replenishment operation. Furthermore, by detecting the phase (rotation) of the developer supply container 1, it is possible to predict the developer remaining amount in the developer supply container 1 to a certain extent.

次に、現像剤センサ２４ｋにより検出された現像剤収容量が所定量に達したと判断された場合、つまり、現像剤センサ２４ｋにより現像剤が検出された場合、駆動モータ５００の駆動をオフし、現像剤の補給動作を停止する（Ｓ１０６）。この補給動作の停止により、一連の現像剤補給工程が終了する。   Next, when it is determined that the developer storage amount detected by the developer sensor 24k has reached a predetermined amount, that is, when the developer is detected by the developer sensor 24k, the drive of the drive motor 500 is turned off. The developer supply operation is stopped (S106). By stopping the replenishment operation, a series of developer replenishment steps are completed.

このような、現像剤補給工程は、画像形成に伴い現像剤が消費されて現像剤ホッパ部２０１ａ内の現像剤収容量が所定未満になると、繰り返し実行される構成となっている。   Such a developer replenishment process is configured to be repeatedly executed when the developer is consumed with image formation and the developer storage amount in the developer hopper portion 201a becomes smaller than a predetermined amount.

〔補給精度、画質、回転駆動負荷の比較〕
次に、図１７〜図２４を用いて、比較例１、変形例１〜５、実施例１の補給精度、画質、回転駆動負荷の比較について説明する。ここでは、本発明の作用効果を最もよく表す駆動受け部１Ａ５、回転振れ規制部１Ａ４、位相検知部１Ａ６の配置の違いによる補給精度、画質、回転駆動負荷の優劣を比較した。実施例１では、後述する実施例２に比べて、カム溝１Ａ３（図２４）が追加されており、カム溝１Ａ３は容器挿入方向最下流側に配置するのが望ましい。なぜならば、カム溝１Ａ３を容器挿入方向最下流側に配置することで、往復部材５１を小型化できるからである。図１７は比較例１の部分拡大図、図１８は変形例１の部分拡大図、図１９は変形例２の部分拡大図、図２０は変形例３の部分拡大図、図２１は変形例４の部分拡大図、図２２は変形例５の部分拡大図、図２３は実施例１の部分拡大図、図２４は実施例１においてカバー５３を外した状態の部分拡大図を示している。 [Comparison of supply accuracy, image quality, rotational drive load]
Next, the comparison of the replenishment accuracy, the image quality, and the rotational drive load of Comparative Example 1, Modified Examples 1 to 5, and Example 1 will be described using FIGS. Here, the superiority or inferiority of the replenishment accuracy, the image quality, and the rotational driving load due to the difference in the arrangement of the drive receiving portion 1A5, the rotational shake regulating portion 1A4 and the phase detecting portion 1A6 which best show the function and effect of the present invention are compared. In the first embodiment, a cam groove 1A3 (FIG. 24) is added as compared with a second embodiment described later, and the cam groove 1A3 is preferably disposed on the most downstream side in the container insertion direction. This is because the reciprocating member 51 can be miniaturized by arranging the cam groove 1A3 on the most downstream side in the container insertion direction. 17 is a partial enlarged view of Comparative Example 1, FIG. 18 is a partial enlarged view of Modification 1, FIG. 19 is a partial enlarged view of Modification 2, FIG. 20 is a partial enlarged view of Modification 3, FIG. 22 is a partial enlarged view of the fifth modification, FIG. 23 is a partial enlarged view of the first embodiment, and FIG. 24 is a partial enlarged view of the first embodiment with the cover 53 removed.

なお、表１中の数値と記号の意味は、以下の通りである。   The meanings of the numerical values and symbols in Table 1 are as follows.

補給精度２０％は、目標値±２０％の補給精度である。位相検知部と回転振れ規制部が隣接して配置され、位相検知部の回転振れ起因による振動を規制することで、位相検知フラグ６２と位相検知センサ６１の検知精度が向上する。その結果、トナー排出時にバッフル部材４０とカム溝１Ａ３の位相決めが正確に行われることで、貯留部４１ｆに貯まる現像剤の量やポンプ部５４の伸縮量も安定するため、補給精度の向上ができる。   Supply accuracy 20% is the supply accuracy of the target value ± 20%. The detection accuracy of the phase detection flag 62 and the phase detection sensor 61 is improved by arranging the phase detection unit and the rotational shake restriction unit adjacent to each other and restricting the vibration caused by the rotational shake of the phase detection unit. As a result, when the toner is discharged, the phase of the baffle member 40 and the cam groove 1A3 is accurately determined, and the amount of developer accumulated in the storage portion 41f and the amount of expansion and contraction of the pump portion 54 are also stabilized. it can.

補給精度３０％は、目標値±３０％の補給精度である。補給精度２０％の場合同様、回転振れ規制部により位相検知部の回転振れ起因による振動を規制することができ、補給精度の向上ができる。しかし、位相検知部と回転振れ規制部が隣接して配置されていないため、補給精度２０％と比較すると、振動規制効果が低く、補給精度が劣ってしまう。   The supply accuracy of 30% is the supply accuracy of the target value ± 30%. Similarly to the case of the replenishment accuracy of 20%, the rotation deflection regulating unit can regulate the vibration caused by the rotation deflection of the phase detection unit, and the replenishment accuracy can be improved. However, since the phase detection unit and the rotational runout regulation unit are not arranged adjacent to each other, the vibration regulation effect is low and the replenishment accuracy is inferior as compared to the replenishment accuracy of 20%.

補給精度４０％は、目標値±４０％の補給精度である。回転振れ規制部を設けていないため、位相検知部の回転振れ起因による振動によって、補給精度３０％と比較すると補給精度が劣ってしまう。   Supply accuracy 40% is the target value ± 40% supply accuracy. Since the rotational runout restricting portion is not provided, the vibration due to the rotational runout of the phase detection portion causes the replenishment accuracy to be inferior as compared to the replenishment accuracy of 30%.

画質◎は、駆動受け部と回転振れ規制部が隣接して配置され、駆動受け部の回転振れ起因による振動を規制することができ、回転駆動伝達が向上するため、画質の向上ができる。   In the image quality ◎, the drive receiving portion and the rotational shake restricting portion are disposed adjacent to each other, and it is possible to restrict the vibration due to the rotational shake of the drive receiving portion.

画質○は、◎の場合同様、回転振れ規制部により駆動受け部の回転振れ起因による振動を規制することができ、駆動伝達が向上するため、画質の向上が期待できる。しかし、駆動受け部と回転振れ規制部が隣接して配置されていないため、◎と比較すると振動規制効果が低く、画質が劣ってしまう。   Similarly to the case of ◎, the image quality ◎ can restrict the vibration due to the rotation sway of the drive receiving portion by the rotation sway restricting portion, and the drive transmission is improved, so improvement of the image quality can be expected. However, since the drive receiving portion and the rotational shake restricting portion are not arranged adjacent to each other, the vibration restricting effect is low compared to ◎, and the image quality is degraded.

画質△は、回転振れ規制部を設けていないため、駆動受け部の回転振れ起因による振動によって、○と比較すると画質が劣ってしまう。   The image quality Δ is inferior to the image quality as compared with O due to the vibration caused by the rotational shake of the drive receiving portion, since the rotational shake restriction portion is not provided.

容器本体１Ａに設けられる位相検知部１Ａ６、回転振れ規制部１Ａ４、駆動受け部１Ａ５は、現像剤補給容器１を現像剤受入れ装置２００へ挿入する際、現像剤受入れ装置２００に設けられる位相検知フラグ６２、ボトル受けローラ２３、駆動ギア２５と当接または噛み合う構成である（図２３）。したがって、現像剤補給容器１を現像剤受入れ装置２００へ挿入する際のユーザーの操作性を考慮すると、「位相検知部」、「回転振れ規制部」、「駆動受け部」の周方向外形は容器挿入方向下流側から徐々に大きくなる配置構成が望ましい。よって、「位相検知部」、「回転振れ規制部」、「駆動受け部」の配置構成で駆動受け部の周方向外形が制限されるため、現像剤補給容器１が回転する際の駆動負荷に影響する。以下に「位相検知部」、「回転振れ規制部」、「駆動受け部」の配置構成の違いによる駆動負荷への影響と表１の記号の意味を説明する。   The phase detection unit 1A6, the rotational shake regulation unit 1A4, and the drive receiving unit 1A5 provided in the container body 1A are phase detection flags provided in the developer receiving device 200 when the developer supply container 1 is inserted into the developer receiving device 200. 62, the bottle receiving roller 23 and the drive gear 25 are in contact or meshed (FIG. 23). Therefore, considering the operability of the user when inserting the developer supply container 1 into the developer receiving device 200, the circumferential external shape of the "phase detection unit", the "rotational runout restriction unit" and the "drive receiving unit" is a container An arrangement configuration in which the size gradually increases from the downstream side in the insertion direction is desirable. Accordingly, the circumferential configuration of the drive receiving portion is limited by the arrangement configuration of the “phase detection portion”, “rotational runout restricting portion”, and “drive receiving portion”, so that the driving load when the developer supply container 1 rotates. Affect. The influence on the drive load due to the difference in the arrangement configuration of the “phase detection unit”, the “rotational shake regulation unit”, and the “drive receiving unit” will be described below and the meaning of the symbols in Table 1 will be described.

回転駆動負荷◎は、「位相検知部」、「回転振れ規制部」、「駆動受け部」のうち、駆動受け部が容器挿入方向最上流側に配置されることで、駆動受け部の外径を１番大きくすることができるため、回転駆動負荷を最も小さくすることができる。   The rotational drive load ◎ is the outer diameter of the drive receiving portion by disposing the drive receiving portion on the most upstream side in the container insertion direction among the “phase detection portion”, “rotational runout restricting portion”, and “drive receiving portion”. Can be made the largest, so the rotational drive load can be made the smallest.

回転駆動負荷○は、「位相検知部」、「回転振れ規制部」、「駆動受け部」のうち、駆動受け部が容器挿入方向上流側から２番目に配置されることで、駆動受け部の外径を２番目に大きくすることができるため、駆動受け部の回転駆動負荷を小さくすることができるが、◎と比べると回転駆動負荷が大きくなる。   The rotational drive load ○ is a drive reception unit of the “phase detection unit”, the “rotational shake regulation unit”, and the “drive reception unit”, which is disposed second from the upstream side in the container insertion direction. Since the outer diameter can be increased to the second, the rotational drive load of the drive receiving portion can be reduced, but the rotational drive load becomes larger compared to ◎.

回転駆動負荷△は、「位相検知部」、「回転振れ規制部」、「駆動受け部」のうち、駆動受け部が容器挿入方向上流側から３番目に配置されることで、駆動受け部の外径が最も小さくなるため、○と比較すると回転駆動負荷が大きくなってしまう。   The rotational drive load Δ is the drive reception unit of the “phase detection unit”, the “rotational runout regulation unit”, and the “drive reception unit”, which is disposed third from the upstream side in the container insertion direction. Since the outer diameter is the smallest, the rotational drive load will be large compared to ○.

（比較例１）
図１７を用いて比較例１について説明する。比較例１は容器本体１Ａに設けられる駆動受け部１Ａ５、位相検知部１Ａ６と（回転振れ規制部１Ａ４はなし）、駆動ギア２５、位相検知フラグ６２、位相検知センサ６１、ボトル受けローラ２３の配置が実施例１とは異なっており、その他の構成は実施例１と同様である。具体的には、現像剤補給容器１の挿入方向下流側（矢印Ａ方向）から位相検知部１Ａ６、駆動受け部１Ａ５の順に並ぶ配置である。 (Comparative example 1)
Comparative Example 1 will be described with reference to FIG. In Comparative Example 1, the arrangement of the drive receiving portion 1A5, the phase detection portion 1A6 and the rotation detection restricting portion 1A4 provided in the container body 1A, the drive gear 25, the phase detection flag 62, the phase detection sensor 61, and the bottle receiving roller 23 The configuration is different from that of the first embodiment, and the other configuration is the same as that of the first embodiment. Specifically, the phase detection unit 1A6 and the drive receiving unit 1A5 are arranged in order from the downstream side (arrow A direction) of the developer supply container 1 in the insertion direction.

この配置だと、回転振れ規制部を設けていないため、位相検知部の回転振れ起因による振動によって補給精度が悪くなり、おおよそ目標値±４０％の補給精度となる。   In this arrangement, since the rotational runout regulating unit is not provided, the replenishment accuracy deteriorates due to the vibration caused by the rotational runout of the phase detection unit, and the replenishment accuracy becomes approximately the target value ± 40%.

画質に関しては、回転振れ規制部を設けていないため、回転振れ規制部を設けた場合と比較すると、駆動受け部の回転振れ起因による振動によって画質が劣ってしまう。   As for the image quality, since the rotational runout regulating unit is not provided, the image quality is degraded due to the vibration caused by the rotational runout of the drive receiving portion as compared with the case where the rotational runout regulating unit is provided.

回転駆動負荷に関しては、駆動受け部が容器挿入方向最上流側に配置されることで駆動受け部の外径を１番大きくすることができるため、回転駆動負荷を最も小さくすることができる。   With regard to the rotational drive load, the outer diameter of the drive receiving portion can be made as large as possible by arranging the drive receiving portion on the most upstream side in the container insertion direction, so the rotational driving load can be minimized.

The other configuration is the same as that of the first embodiment.

The supply accuracy can also be improved, and the supply accuracy is approximately the target value ± 20%.

画質に関しては、回転振れ規制部により駆動受け部の回転振れ起因による振動を規制することで、駆動伝達が向上し、回転振れ規制部１Ａ４を設けていない比較例１よりも画質の向上が期待できる。しかし、駆動受け部と回転振れ規制部が隣接して配置されていないため、駆動受け部と回転振れ規制部が隣接して配置されている場合と比較すると、振動規制効果が低く、画質が劣ってしまう。   With regard to the image quality, the drive transmission is improved by restricting the vibration due to the rotational shake of the drive receiving portion by the rotational shake restricting portion, and the image quality can be expected to be improved more than Comparative Example 1 where the rotational shake restricting portion 1A4 is not provided. . However, since the drive receiving portion and the rotational shake restricting portion are not arranged adjacent to each other, the vibration restricting effect is low and the image quality is inferior as compared with the case where the drive receiving portion and the rotational shake restricting portion are arranged adjacent to each other. It will

回転駆動負荷に関しては、「位相検知部（被検知部）」、「回転振れ規制部（当接部）」、「駆動受け部」のうち、駆動受け部が容器挿入方向上流側から３番目に配置されることで、駆動受け部の外径が最も小さくなるため、駆動受け部が容器挿入方向上流側から１番目に配置された場合や２番目に配置された場合と比較すると、回転駆動負荷が大きくなってしまう。   Regarding the rotational drive load, the drive receiving portion is the third from the upstream side in the container insertion direction among the “phase detection portion (detected portion)”, the “rotational runout portion (contact portion)”, and the “drive receiving portion”. By being disposed, the outer diameter of the drive receiving portion becomes the smallest, so compared with the case where the drive receiving portion is disposed first from the upstream side in the container insertion direction or compared to the case of being disposed second, Becomes large.

回転駆動負荷に関しては、「位相検知部（被検知部）」、「回転振れ規制部（当接部）」、「駆動受け部」のうち、駆動受け部が容器挿入方向上流側から３番目に配置されることで、駆動受け部の外径が最も小さくなるため、駆動受け部が容器挿入方向上流側から１番目に配置された場合や２番目に配置された場合と比較すると、回転駆動負荷が大きくなってしまう。   Regarding the rotational drive load, the drive receiving portion is the third from the upstream side in the container insertion direction among the “phase detection portion (detected portion)”, the “rotational runout portion (contact portion)”, and the “drive receiving portion”. By being disposed, the outer diameter of the drive receiving portion becomes the smallest, so compared with the case where the drive receiving portion is disposed first from the upstream side in the container insertion direction or compared to the case of being disposed second, Becomes large.

（実施例１）
図２３、図２４を用いて実施例１について説明する。実施例１の容器本体１Ａに設けられる駆動受け部１Ａ５、回転振れ規制部１Ａ４、位相検知部１Ａ６の配置は現像剤補給容器１の挿入方向下流側（矢印Ａ方向）からカム溝１Ａ３、位相検知部１Ａ６、回転振れ規制部１Ａ４、駆動受け部１Ａ５の順に並ぶ構成である。 Example 1
The first embodiment will be described with reference to FIGS. 23 and 24. FIG. The arrangement of the drive receiving portion 1A5, the rotational runout regulating portion 1A4, and the phase detecting portion 1A6 provided in the container main body 1A of the first embodiment is the cam groove 1A3 from the downstream side (arrow A direction) of the developer supply container 1 insertion direction The unit 1A6, the rotational runout regulating unit 1A4, and the drive receiver 1A5 are arranged in this order.

この配置だと、位相検知部と回転振れ規制部が隣接して配置され、位相検知部の回転振れ起因による振動を効率よく規制することで、回転振れ規制部１Ａ４を設けていない比較例１よりも補給精度の向上が期待でき、おおよそ目標値±２０％の補給精度となる。   With this arrangement, the phase detection unit and the rotational shake restriction unit are disposed adjacent to each other, and efficiently restricting the vibration due to the rotational shake caused by the phase detection unit, compared with Comparative Example 1 in which the rotational fluctuation restriction unit 1A4 is not provided. Also, it is possible to expect improvement in the supply accuracy, and the supply accuracy is approximately the target value ± 20%.

画質に関しては、駆動受け部と回転振れ規制部が隣接して配置され、駆動受け部の回転振れ起因による振動を効率よく規制することで、駆動伝達が向上し、回転振れ規制部１Ａ４を設けていない比較例１よりも画質の向上が期待できる。   With regard to the image quality, the drive receiving portion and the rotational shake restricting portion are arranged adjacent to each other, and the drive transmission is improved by efficiently restricting the vibration caused by the rotational shake of the drive receiving portion, and the rotational shake restricting portion 1A4 is provided. The improvement of the image quality can be expected more than the comparative example 1 which does not have.

回転駆動負荷に関しては、駆動受け部が容器挿入方向最上流側に配置されることで、駆動受け部の外径を１番大きくすることができるため、回転駆動負荷を最も小さくすることができる。   With regard to the rotational drive load, by disposing the drive receiving portion on the most upstream side in the container insertion direction, the outer diameter of the drive receiving portion can be made as large as possible, and the rotational drive load can be minimized.

上述の比較結果では、比較例１、変形例１〜５、実施例１の補給精度、画質、回転駆動負荷の優劣を述べているが、本発明においては「駆動受け部１Ａ５」、「回転振れ規制部１Ａ４」、「位相検知部１Ａ６」をどのように配置することも可能である。   In the above comparison results, although the replenishment accuracy, the image quality, and the superiority or inferiority of the rotational drive load of Comparative Example 1, Modified Examples 1 to 5, and Example 1 are described, in the present invention, “drive receiving portion 1A5”, “rotational shake It is also possible to arrange the restricting portion 1A4 "and the" phase detection portion 1A6 "in any way.

しかし、補給精度、画質、回転駆動負荷の３つの評価項目を比較した場合、「駆動受け部１Ａ５」、「回転振れ規制部１Ａ４」、「位相検知部１Ａ６」の配置構成により、各評価項目の優劣が決まる。以下に「駆動受け部１Ａ５」、「回転振れ規制部１Ａ４」、「位相検知部１Ａ６」の好適な配置構成とその理由を述べる。   However, when the three evaluation items of the replenishment accuracy, the image quality, and the rotational driving load are compared, the arrangement configuration of “drive receiving portion 1A5”, “rotational runout regulating portion 1A4”, and “phase detection portion 1A6” The superiority is decided. The preferable arrangement configuration of “drive receiving portion 1A5”, “rotational shake regulating portion 1A4”, and “phase detection portion 1A6” and the reason thereof will be described below.

回転駆動負荷に関しては、駆動受け部１Ａ５を容器挿入方向最上流側に配置することで駆動受け部の外径を１番大きくすることができるため、回転駆動負荷を最も小さくすることができる。   With regard to the rotational drive load, by disposing the drive receiving portion 1A5 on the most upstream side in the container insertion direction, the outer diameter of the drive receiving portion can be made as large as one, so the rotational drive load can be minimized.

補給精度に関しては、位相検知部と回転振れ規制部を隣接して配置することで、位相検知部の回転振れ起因による振動を効率よく規制することができ、位相検知フラグ６２と位相検知センサ６１の検知精度が向上する。その結果、トナー排出時にバッフル部材４０の位相決めが精確に行われるため、回転振れ規制部１Ａ４を設けていない比較例１よりも補給精度の向上ができ、おおよそ目標値±２０％の補給精度となる。   With regard to the replenishment accuracy, by disposing the phase detection unit and the rotational shake restriction unit adjacent to each other, it is possible to efficiently regulate the vibration caused by the rotational shake of the phase detection unit. Detection accuracy is improved. As a result, since the phasing of the baffle member 40 is accurately performed at the time of toner discharge, the replenishment accuracy can be improved more than Comparative Example 1 in which the rotational runout restricting portion 1A4 is not provided. Become.

画質に関しては、駆動受け部と回転振れ規制部を隣接して配置することで、駆動受け部の回転振れ起因による振動を効率よく規制することができ、駆動伝達が向上し、回転振れ規制部１Ａ４を設けていない比較例１よりも画質の向上が期待できる。   With regard to the image quality, by arranging the drive receiving portion and the rotational shake restricting portion adjacent to each other, it is possible to efficiently regulate the vibration due to the rotational shake of the drive receiving portion, and the drive transmission is improved. The improvement of the image quality can be expected as compared with Comparative Example 1 in which is not provided.

以上より、最も好適な構成は容器挿入方向下流側からカム溝１Ａ３、位相検知部１Ａ６、回転振れ規制部１Ａ４、駆動受け部１Ａ５と配置する構成、つまり「実施例１」の構成である。   As described above, the most preferable configuration is the configuration in which the cam groove 1A3, the phase detection unit 1A6, the rotational shake regulation unit 1A4, and the drive receiving unit 1A5 are arranged from the downstream side in the container insertion direction, that is, the configuration of “first embodiment”.

本実施例によれば、現像剤補給時における現像剤補給容器の回転振れを回転振れ規制部で規制することによって、位相検知部と駆動受け部の双方の回転振れを低減できる。その結果、駆動伝達と位相検知の双方の精度向上ができる。さらに、現像剤補給容器の回転による振動も低減できるため、画質の向上ができる。   According to this embodiment, the rotational runout of both the phase detection unit and the drive receiving unit can be reduced by restricting the rotational runout of the developer supply container at the time of developer replenishment by the rotational runout regulating unit. As a result, the accuracy of both drive transmission and phase detection can be improved. Furthermore, since the vibration due to the rotation of the developer supply container can also be reduced, the image quality can be improved.

特に本実施例においては、位相検知部１Ａ６の位相検知結果により、容器本体1Ａ、及び容器本体1Ａ内に配置されるバッフル部材４０の回転量や回転停止位置が制御されることから、前記回転振れ規制部１Ａ４を隣接配置することで容器内での現像剤の搬送量及びタイミングの制御が容易且つ正確に行える。   In particular, in the present embodiment, the rotation amount and the rotation stop position of the container body 1A and the baffle member 40 disposed in the container body 1A are controlled by the phase detection result of the phase detection unit 1A6. By arranging the regulating portions 1A4 adjacent to each other, control of the transport amount and timing of the developer in the container can be easily and accurately performed.

更に前述したように本実施の形態では、容器本体１Ａ４の回転により、現像剤の排出に寄与するポンプ部５４を作動させる構成を採用している。そのため前記位相検知部１Ａ６による検知が正確に行えることは、現像剤補給容器１からの排出量が正確に制御できることに繋がる。   Furthermore, as described above, in the present embodiment, a configuration is employed in which the pump portion 54 contributing to the discharge of the developer is operated by the rotation of the container main body 1A4. Therefore, accurate detection by the phase detection unit 1A6 leads to accurate control of the discharge amount from the developer supply container 1.

以上から位相検知部１Ａ６、回転振れ規制部１Ａ４、駆動受け部１Ａ５の配置については、本実施例で示したバッフル部材４０やポンプ部５４を有する現像剤補給容器においては特に有効である。   As described above, the arrangement of the phase detection unit 1A6, the rotational runout restriction unit 1A4, and the drive receiving unit 1A5 is particularly effective in the developer supply container having the baffle member 40 and the pump unit 54 shown in this embodiment.

以下の説明では、画像形成装置の基本構成についての説明を省略し、画像形成装置に搭載される現像剤補給システム、つまり、現像剤受入れ装置（現像剤補給装置）と現像剤補給容器の構成について順に説明する。   In the following description, the description of the basic configuration of the image forming apparatus is omitted, and the developer replenishing system mounted on the image forming apparatus, that is, the configurations of the developer receiving apparatus (developer replenishing apparatus) and the developer replenishing container It will be described in order.

（現像剤受入れ装置）
まず、現像剤受入れ装置２００について図２６を用いて説明する。図２６は実施例２における現像剤受入れ装置２００に現像剤補給容器１（図２５）を矢印Ａ方向に挿入する途中の様子を示す断面斜視図である。 (Developer receiving device)
First, the developer receiving device 200 will be described with reference to FIG. FIG. 26 is a cross-sectional perspective view showing a state in the middle of inserting the developer supply container 1 (FIG. 25) in the direction of arrow A into the developer receiving device 200 in the second embodiment.

図２６に示すように、現像剤受入れ装置２００には、主に後述する現像剤補給容器１の回転振れ規制部（当接部）１Ａ４と当接するボトル受けローラ２３、現像剤補給容器１の駆動受け部１Ａ５に回転駆動力を伝達する駆動ギア２５が設けられている。また現像剤受入れ装置２００には、現像剤補給容器１の位相検知部（被検知部）１Ａ６と当接することにより現像剤補給容器１の位相（回転）を検知する位相検知フラグ６２、位相検知フラグ６２を検知する位相検知センサ６１が設けられている。さらに現像剤受入れ装置２００には、現像剤補給容器１から排出され現像剤を一時的に貯留する現像剤ホッパ部２０１ａ、現像剤ホッパ部２０１ａ内の現像剤を現像装置２０１（図１）へ搬送するスクリュー部材２７が設けられている。さらに現像剤受入れ装置２００には、後述する現像剤補給容器１の封止部材２と係合する封止部材係合部２０、現像剤ホッパ部２０１ａに連通する隔壁２００ｆが設けられている。この隔壁２００ｆには現像剤補給容器１の一部を回転可能に支持し、かつ現像剤ホッパ部２０１ａを密封する不図示のシール部材が設けられている。尚、位相検知フラグ６２は弾性部材（不図示）により鉛直下方向に付勢されており、回転軸Ｑ（図１７）を中心に回転可能となっている。   As shown in FIG. 26, in the developer receiving device 200, a bottle receiving roller 23 that contacts a rotational runout regulating portion (abutment portion) 1A4 of the developer replenishing container 1, which will be described later, and a drive of the developer replenishing container 1 A drive gear 25 for transmitting a rotational drive force to the receiving portion 1A5 is provided. In the developer receiving apparatus 200, a phase detection flag 62 for detecting the phase (rotation) of the developer supply container 1 by coming into contact with the phase detection unit (detected unit) 1A6 of the developer supply container 1; A phase detection sensor 61 that detects 62 is provided. Further, the developer receiving unit 200 transports the developer in the developer hopper portion 201a which temporarily discharges the developer discharged from the developer supply container 1 and the developer in the developer hopper portion 201a to the developing device 201 (FIG. 1). A screw member 27 is provided. Further, the developer receiving device 200 is provided with a sealing member engaging portion 20 which engages with a sealing member 2 of the developer supply container 1 described later, and a partition wall 200f communicating with the developer hopper portion 201a. The partition wall 200f is provided with a seal member (not shown) which rotatably supports a part of the developer supply container 1 and seals the developer hopper portion 201a. The phase detection flag 62 is biased vertically downward by an elastic member (not shown), and can rotate about the rotation axis Q (FIG. 17).

（現像剤補給容器）
続いて、実施例２の現像剤補給容器１について図２５、図２６、図２７を用いて説明する。図２５は実施例１における現像剤補給容器１の部分斜視図である。図２６は現像剤補給容器を現像剤受入れ装置２００に対して矢印Ａ方向へ挿入途中の様子を表す部分斜視図である。図２７（ａ）〜（ｃ）は現像剤補給容器１を現像剤受入れ装置２００に対して矢印Ａ方向に挿入完了するまでの様子を段階的に表す部分断面図である。 (Developer supply container)
Subsequently, the developer supply container 1 of Example 2 will be described with reference to FIGS. 25, 26, and 27. FIG. FIG. 25 is a partial perspective view of the developer supply container 1 according to the first embodiment. FIG. 26 is a partial perspective view showing a state in which the developer supply container is being inserted into the developer receiving device 200 in the direction of arrow A. As shown in FIG. FIGS. 27 (a) to 27 (c) are partial sectional views showing the state until the developer supply container 1 is completely inserted into the developer receiving device 200 in the direction of arrow A in a stepwise manner.

図２５に示すように、現像剤補給容器１は主に容器本体１Ａ、フランジ部４１、バッフル部材４０、封止部材２から構成される。   As shown in FIG. 25, the developer supply container 1 mainly includes a container main body 1 </ b> A, a flange portion 41, a baffle member 40, and a sealing member 2.

現像剤補給容器１は略円筒形状に形成され、その一端面のほぼ中央に容器本体１Ａの円筒部より小径の排出口１ａが突設されている。排出口１ａには排出口１ａを閉じる封止部材２が設けてあり、図２７（ａ）〜（ｃ）に関連した後述する説明にて理解されるように、この封止部材２が現像剤補給容器１に対して相対的にスライド移動（図２５矢印Ａもしくは矢印Ｂ方向）することにより、排出口１ａの開閉動作を行う構成になっている。   The developer supply container 1 is formed in a substantially cylindrical shape, and a discharge port 1a having a diameter smaller than that of the cylindrical portion of the container main body 1A is protruded substantially at the center of one end surface. The discharge port 1a is provided with a sealing member 2 for closing the discharge port 1a, and this sealing member 2 is a developer, as will be understood in the following description related to FIGS. 27 (a) to 27 (c). By sliding relative to the supply container 1 (in the direction of arrow A or arrow B in FIG. 25), the opening / closing operation of the discharge port 1a is performed.

現像剤補給容器１の内部構成について図２５を用いて説明する。上述のように、現像剤補給容器１は略円筒形状をしており、現像剤受入れ装置２００に略水平に配置され、現像剤受入れ装置２００から回転駆動力を受けて、軸Ｐを中心に矢印Ｒ方向に回転する構成になっている。   The internal configuration of the developer supply container 1 will be described with reference to FIG. As described above, the developer supply container 1 has a substantially cylindrical shape, is disposed substantially horizontally in the developer receiving device 200, receives a rotational driving force from the developer receiving device 200, and is an arrow around the axis P It is configured to rotate in the R direction.

そして現像剤補給容器１の内部には現像剤を搬送するためのバッフル部材４０が配置される。現像剤補給容器１が回転することにより、螺旋状の突起１Ａ１によって現像剤補給容器１の上流側から下流側へ（矢印Ａ方向）搬送されてきた現像剤はやがてバッフル部材４０に到達する。傾斜突起４０ａの一端は、排出口１ａに接続するように設けられており、最終的に現像剤はバッフル部材４０の回転に伴って、この突起４０ａを滑り落ちるように排出口１ａへ搬送される。   A baffle member 40 for transporting the developer is disposed inside the developer supply container 1. As the developer supply container 1 rotates, the developer conveyed from the upstream side to the downstream side of the developer supply container 1 (the direction of the arrow A) by the helical protrusion 1A1 reaches the baffle member 40 soon. One end of the inclined projection 40a is provided to be connected to the discharge port 1a, and finally, the developer is conveyed to the discharge port 1a so as to slide down the projection 40a as the baffle member 40 rotates.

現像剤補給容器１の内部構成は、現像剤補給容器１が現像剤受入れ装置２００から回転駆動力を受けることにより、現像剤を排出する機能を有するものであれば、特にその内部の形状や構成について限定するものではない。つまり、現像剤補給容器１の内部構成については、実施形態１のように一般的によく知られている螺旋状の突起１Ａ１を形成したものや、その他の構成であっても構わない。   The internal configuration of the developer supply container 1 is particularly the internal shape and configuration, as long as the developer supply container 1 receives the rotational driving force from the developer receiving device 200 and discharges the developer. There is no limitation on That is, the internal configuration of the developer supply container 1 may be a generally well-known spiral projection 1A1 as in the first embodiment, or any other configuration.

（容器本体）
容器本体１Ａについて、図２５を用いて説明する。図２５に示すように、容器本体１Ａは内部に現像剤を収容する現像剤収容部１Ａ２と、容器本体１Ａが軸Ｐに対してＲ方向に回転することによって現像剤収容部１Ａ２内の現像剤を矢印Ａ方向ヘ搬送する螺旋状の突起１Ａ１から構成される。 (Container body)
The container main body 1A will be described with reference to FIG. As shown in FIG. 25, the container body 1A contains a developer accommodating portion 1A2 for accommodating the developer therein, and the developer in the developer accommodating portion 1A2 when the container body 1A rotates in the R direction with respect to the axis P. Are conveyed in the direction of arrow A, and are composed of helical projections 1A1.

（フランジ部）
フランジ部４１について図２５、図２６を用いて説明する。図２５に示すように、フランジ部４１は、容器本体１Ａに取り付けられ、フランジ部４１と容器本体１Ａは回転軸Ｐを中心にして矢印Ｒ方向に一体的に回転する。フランジ部４１は、略中空円筒形状に形成され、その一端面のほぼ中央に円筒部が突設されており、この円筒部先端側が現像剤を現像剤ホッパ部２０１ａ（図２６）へ排出するための排出口１ａとなっている。 (Flange part)
The flange portion 41 will be described with reference to FIGS. 25 and 26. As shown in FIG. 25, the flange portion 41 is attached to the container main body 1A, and the flange portion 41 and the container main body 1A integrally rotate around the rotation axis P in the arrow R direction. The flange portion 41 is formed in a substantially hollow cylindrical shape, and a cylindrical portion protrudes from substantially the center of one end surface thereof, and the tip end side of the cylindrical portion discharges the developer to the developer hopper portion 201a (FIG. 26). The outlet 1a of the

図２６に示すように、フランジ部４１の他端面の外周側の全周に渡って、現像剤受入れ装置２００からの回転駆動力を受ける駆動受け部（駆動入力部）１Ａ５、ボトル受けローラ２３と当接することにより現像剤補給容器１の回転振れを規制する回転振れ規制部１Ａ４、周面の一部に回転位相を検知する位相検知部１Ａ６が、一体的に形成されている。   As shown in FIG. 26, over the entire circumference of the outer peripheral side of the other end surface of the flange portion 41, a drive receiving portion (drive input portion) 1A5 receiving the rotational driving force from the developer receiving device 200 and a bottle receiving roller 23 A rotational runout regulating portion 1A4 that regulates rotational runout of the developer supply container 1 by coming into contact, and a phase detection portion 1A6 that senses the rotational phase on a part of the circumferential surface are integrally formed.

尚、本実施例２では、駆動受け部１Ａ５と回転振れ規制部１Ａ４と位相検知部１Ａ６がフランジ部４１と一体的に形成されている例を示したが、これに限定されるものではない。例えば、駆動受け部１Ａ５と回転振れ規制部１Ａ４と位相検知部１Ａ６を別体として成形し、フランジ部４１に一体的に取り付ける構成等であってもよい。   In the second embodiment, the drive receiving portion 1A5, the rotational shake restricting portion 1A4 and the phase detection portion 1A6 are integrally formed with the flange portion 41, but the present invention is not limited to this. For example, the drive receiving portion 1A5, the rotational runout restricting portion 1A4, and the phase detection portion 1A6 may be separately formed and integrally attached to the flange portion 41.

また、現像剤収容部１Ａ２は、容器本体１Ａだけではなく、容器本体１Ａとフランジ部４１の内部スペースを合わせたものとなる。   Further, the developer accommodating portion 1A2 is not only the container body 1A but also the internal space of the container body 1A and the flange portion 41.

また、本実施例２では、回転振れ規制部１Ａ４に対して位相検知部１Ａ６の形状を凹形状としたが、回転振れ規制部１Ａ４に対して位相検知部１Ａ６の形状を凸形状にしてもかまわない。   In the second embodiment, the phase detection unit 1A6 has a concave shape with respect to the rotational shake restricting unit 1A4, but the phase detection unit 1A6 may have a convex shape with respect to the rotational shake restriction unit 1A4. Absent.

実施例２では、現像剤補給容器１がＲ方向に回転して現像剤を補給する際（図３０）、駆動受け部１Ａ５と位相検知部１Ａ６の双方のラジアル方向のガタ防止効果の向上を目的として、回転振れ規制部１Ａ４の真円度を０．０５とした。回転振れ規制部１Ａ４は真円に近いほど、より高いラジアル方向のガタ防止効果が期待できるが、必要以上の幾何公差を設けるとコストアップにつながるため、真円度を０．０５とした。   In the second embodiment, when the developer supply container 1 rotates in the R direction to supply the developer (FIG. 30), the purpose is to improve the effect of preventing the radial direction of both the drive receiving portion 1A5 and the phase detection portion 1A6. The roundness of the rotation control unit 1A4 is set to 0.05. As the rotational runout restricting portion 1A4 is closer to a true circle, higher radial rattle prevention effect can be expected, but providing a geometric tolerance more than necessary leads to an increase in cost, so the roundness is set to 0.05.

このような構成とすることで、現像剤補給時に現像剤補給容器１が図３０の矢印Ｒ方向に回転する際、真円に近い形状の回転振れ規制部１Ａ４とボトル受けローラ２３が当接することで位相検知部１Ａ６と駆動受け部１Ａ５の双方の回転振れを抑制できる。その結果、駆動伝達と位相検知の双方の精度向上が期待できる。さらに、現像剤補給容器１の回転による振動も低減できるため、画質の向上が期待できる。   With such a configuration, when the developer supply container 1 rotates in the direction of arrow R in FIG. 30 at the time of developer supply, the rotational runout regulating portion 1A4 having a shape close to a perfect circle and the bottle receiving roller 23 abut. Thus, the rotational shake of both the phase detection unit 1A6 and the drive receiving unit 1A5 can be suppressed. As a result, it is expected to improve the accuracy of both drive transmission and phase detection. Further, since the vibration due to the rotation of the developer supply container 1 can also be reduced, improvement in image quality can be expected.

また、駆動受け部１Ａ５及び位相検知部１Ａ６を回転振れ規制部１Ａ４に隣接して配置した構成としている。このような構成とすることで、駆動受け部１Ａ５と位相検知部１Ａ６とを離れた位置に配置した構成に比べて、位相検知部１Ａ６と駆動受け部１Ａ５の双方の回転振れをより抑制できる。その結果、駆動伝達と位相検知の双方の精度向上や、画質の向上がより期待できる。   Further, the drive receiving portion 1A5 and the phase detection portion 1A6 are disposed adjacent to the rotational shake restricting portion 1A4. With such a configuration, rotational runout of both the phase detection unit 1A6 and the drive reception unit 1A5 can be further suppressed as compared with a configuration in which the drive reception unit 1A5 and the phase detection unit 1A6 are disposed at separate positions. As a result, it is possible to further expect improvement in accuracy of both drive transmission and phase detection and improvement in image quality.

（バッフル部材）
バッフル部材４０について図２５を用いて説明する。図２５に示すように、バッフル部材４０は容器本体１Ａに取り付けられ、バッフル部材４０と容器本体１Ａは軸Ｐを中心にして一体的に矢印Ｒ方向に回転する。バッフル部材４０には表裏両面に傾斜した傾斜突起４０ａが複数設けられ、傾斜突起４０ａの一端は排出口１ａに達している。 (Baffle member)
The baffle member 40 will be described with reference to FIG. As shown in FIG. 25, the baffle member 40 is attached to the container body 1A, and the baffle member 40 and the container body 1A integrally rotate around the axis P in the arrow R direction. The baffle member 40 is provided with a plurality of inclined projections 40a inclined on both the front and back sides, and one end of the inclined projection 40a reaches the discharge port 1a.

（封止部材）
次に、実施例２における封止部材２の構成について図２８〜図３０を用いて更に説明する。図２８（ａ）と図２８（ｂ）は封止部材２の斜視図である。図２９は封止部材２の（ａ）正面図、（ｂ）左側面図、（ｃ）右側面図、（ｄ）上面図、（ｅ）Ｃ−Ｃ断面図である。図３０は実施例２における現像剤補給容器１が現像剤受入れ装置２００の封止部材係合部２０と係合し、現像剤を供給している状態の断面斜視図である。 (Sealing member)
Next, the structure of the sealing member 2 in Example 2 is further demonstrated using FIGS. 28-30. 28 (a) and 28 (b) are perspective views of the sealing member 2. FIG. FIG. 29 is (a) front view, (b) left side view, (c) right side view, (d) top view, (e) CC cross-sectional view of the sealing member 2. FIG. 30 is a cross-sectional perspective view of a state in which the developer supply container 1 in the second embodiment is engaged with the sealing member engaging portion 20 of the developer receiving device 200 and supplies the developer.

図２８〜図３０において、封止部材２は現像剤補給容器１の排出口１ａを開封可能に封止する封止部２ｂを備えている。また、封止部２ｂは排出口１ａの内径よりも適当量大きく設定されたシール部２ａを備えている。シール部２ａは排出口１ａを形成する内壁１ｂと圧入することにより密着してシールしていることから、適度な弾性を有することが好ましい。   In FIGS. 28 to 30, the sealing member 2 is provided with a sealing portion 2b which seals the discharge port 1a of the developer supply container 1 in an openable manner. Further, the sealing portion 2b is provided with a sealing portion 2a which is set to a suitable amount larger than the inner diameter of the discharge port 1a. Since the seal portion 2a is in close contact with the inner wall 1b forming the discharge port 1a by press-fitting, the seal portion 2a preferably has appropriate elasticity.

（弾性変形部）
次に、弾性変形部２ｃについて図２８〜図３０を用いて説明する。封止部材２は複数の弾性変形部２ｃを備えている。 (Elastic deformation section)
Next, the elastically deformable portion 2c will be described with reference to FIGS. The sealing member 2 is provided with a plurality of elastically deformable portions 2c.

封止部材２の複数の弾性変形部２ｃには、それぞれ１つの係合突起３が設けられている。この係合突起３が封止部材係合部２０によって半径方向内側（図２９（ｅ）矢印Ｄ方向）へ押圧されることで、弾性変形部２ｃは容易に弾性変形可能である。更に、係合突起３と対となって解除突起４が設けられており、係合突起３と解除突起４は弾性変形部２ｃを介して一体となっている。   Each of the plurality of elastically deformable portions 2 c of the sealing member 2 is provided with one engagement protrusion 3. The elastically deformable portion 2c can be easily elastically deformed by pressing the engaging protrusion 3 radially inward (in the direction of the arrow D in FIG. 29E) by the sealing member engaging portion 20. Furthermore, a release protrusion 4 is provided in a pair with the engagement protrusion 3, and the engagement protrusion 3 and the release protrusion 4 are integrated via an elastic deformation portion 2 c.

一方、現像剤受入れ装置２００に設けた封止部材係合部２０の係止穴２０ｈは封止部材２の係止面３ｂと係止するように構成されている。   On the other hand, the locking hole 20 h of the sealing member engaging portion 20 provided in the developer receiving device 200 is configured to lock with the locking surface 3 b of the sealing member 2.

（係合突起）
係合突起３は弾性変形部２ｃの円筒面よりも半径方向外側に向かって突出している。この係合突起３は、現像剤補給容器１と封止部材２とを離間させる（排出口１ａを閉状態から開状態にする）際に、封止部材２を現像剤受入れ装置２００の被係止部としての係止穴２０ｈにスナップフィット的に係止させるための係止部として作用する係止面３ｂを有している。また、封止部材２は弾性変形を補助、促進するためのスリット溝２ｅを備えている。そして、係合突起３及び解除突起４は、半径方向内側（矢印Ｄ方向）に押圧された場合には半径方向内側（矢印Ｄ方向）に弾性変形し、半径方向内側（矢印Ｄ方向）の押圧を解除した場合には、半径方向外側（矢印Ｄと逆方向）に弾性変形が回復する構成となっている。 (Engaging projection)
The engagement protrusions 3 project radially outward of the cylindrical surface of the elastically deformable portion 2c. The engaging projection 3 separates the developer supply container 200 from the developer supply device 200 when the developer supply container 1 and the sealing member 2 are separated (when the discharge port 1 a is opened from the closed state). It has a locking surface 3b which acts as a locking portion for locking in a snap-fit manner in a locking hole 20h as a locking portion. Further, the sealing member 2 is provided with a slit groove 2e for assisting and promoting elastic deformation. When the engaging projection 3 and the releasing projection 4 are pressed inward in the radial direction (direction of arrow D), they are elastically deformed inward in the radial direction (direction of arrow D) and pressed inward in the radial direction (direction of arrow D). Is released, the elastic deformation is restored radially outward (in the direction opposite to the arrow D).

すなわち、図３０に示すように、係合突起３は現像剤補給容器１と封止部材２とを相対的にスライド移動（矢印Ａ方向）させて排出口１ａを開閉するために封止部材係合部２０と係止される係止機能（抜け止め機能）を、弾性変形部２ｃ、係止面３ｂで果たしている。   That is, as shown in FIG. 30, the engaging protrusion 3 relatively slides the developer supply container 1 and the sealing member 2 (in the direction of arrow A) to open and close the discharge port 1a. The elastically deformable portion 2c and the locking surface 3b function as a locking function (retaining function) to be locked with the joint portion 20.

また、封止部材２を現像剤受入れ装置２００の封止部材係合部２０に挿入する際に、スムーズに挿入されるように、係合突起３はテーパ面３ｃを有している。   In addition, when the sealing member 2 is inserted into the sealing member engaging portion 20 of the developer receiving device 200, the engaging protrusion 3 has a tapered surface 3c so as to be smoothly inserted.

図２６に示すように、現像剤補給容器１を現像剤受入れ装置２００に対して矢印Ａ方向に挿入していくと、やがて封止部材係合部２０と封止部材２の係合が開始され、テーパ面３ｃと係合突起３は封止部材２の内面から押圧力を受け、弾性変形部２ｃが半径方向内側に変位する。更に現像剤補給容器１の挿入を進めると、テーパ面３ｃと係合突起３が封止部材係合部２０の内面から受けていた押圧力が解除される。すると、弾性変形部２ｃは弾性変位した状態から復帰し、封止部材（係止部）２と現像剤受入れ装置（被係止部）２００との係止が完了する。   As shown in FIG. 26, when the developer supply container 1 is inserted into the developer receiving device 200 in the direction of the arrow A, the engagement between the sealing member engaging portion 20 and the sealing member 2 is started soon. The tapered surface 3c and the engagement projection 3 receive a pressing force from the inner surface of the sealing member 2, and the elastically deformable portion 2c is displaced radially inward. When the insertion of the developer supply container 1 is further advanced, the pressing force that the tapered surface 3 c and the engagement protrusion 3 have received from the inner surface of the sealing member engaging portion 20 is released. Then, the elastically deformable portion 2 c returns from the elastically displaced state, and the locking between the sealing member (locking portion) 2 and the developer receiving device (locked portion) 200 is completed.

そして、係止が完了した後、封止部材２と現像剤補給容器１とを相対的に離間させるために、封止部材２を矢印Ａ方向へスライド移動させることで、排出口１ａが閉状態から開状態とされ、現像剤排出可能状態となる。尚、実施例２では、容器本体１Ａに固定されたフランジ部４１を現像剤受入れ装置２００に係止させてスライド方向の移動を規制した状態において、封止部材２を前進（図３０、Ａ方向）、後退（図３０、Ｂ方向）させることで排出口１ａの開封、密封を行っている。もちろん、封止部材２を現像剤受入れ装置２００に係止させてスライド方向の移動を規制した状態において、容器本体１Ａを前進（図３０、Ａ方向）、後退（図３０、Ｂ方向）させることで排出口１ａの開封、密封を行う構成であってもよい。   Then, after locking is completed, the discharge port 1a is closed by sliding the sealing member 2 in the direction of the arrow A in order to separate the sealing member 2 and the developer supply container 1 relative to each other. And the developer can be discharged. In the second embodiment, the sealing member 2 is advanced in the state where the movement in the sliding direction is restricted by locking the flange portion 41 fixed to the container main body 1A to the developer receiving device 200 (FIG. 30, A direction The discharge port 1a is opened and sealed by retracting (FIG. 30, B direction). Of course, in a state where the sealing member 2 is locked to the developer receiving device 200 to restrict the movement in the sliding direction, the container body 1A is advanced (FIG. 30, A direction) and retracted (FIG. 30, B direction). The configuration may be such that the discharge port 1a is opened and sealed.

（解除突起）
次に係合突起３と対を成して設けている解除突起４について図２８〜図３０を用いて説明する。この解除突起４は、現像剤補給容器１を交換する際に封止部材係合部２０に係合した封止部材２の係止状態を解除するための突起であって、この係止を解除して古い現像剤補給容器１を取り出して新しい現像剤補給容器１に交換するためのものである。 (Release projection)
Next, the release projection 4 provided in a pair with the engagement projection 3 will be described with reference to FIGS. The release projection 4 is a projection for releasing the locked state of the sealing member 2 engaged with the sealing member engaging portion 20 when the developer supply container 1 is replaced, and the lock is released. Then, the old developer supply container 1 is taken out and replaced with a new developer supply container 1.

この解除突起４は、現像剤受入れ装置２００の解除部材２１のスライド動作（図３０のＢ方向）により、解除突起４が押圧されることで弾性変形部２ｃが半径方向内側に弾性変形し、係合突起３と封止部材係合部２０の係止状態を解除する役割を果たしている。   When the release projection 4 is pressed by the slide operation (direction B in FIG. 30) of the release member 21 of the developer receiving device 200, the elastic deformation portion 2c elastically deforms inward in the radial direction. It plays the role of releasing the locked state of the joint projection 3 and the sealing member engaging portion 20.

尚、本例では、係合突起３及び解除突起４を円周方向に４分割した位置にそれぞれペアとなるように設けたが、２箇所あるいは３箇所などその位置や数については任意に設定してもかまわない。   In this example, the engaging projection 3 and the releasing projection 4 are provided in pairs at positions circumferentially divided into four, but the positions and the number thereof may be set arbitrarily, such as two or three. It does not matter.

（フランジ係止部）
次に封止部材２のもう一つの機能である、フランジ部４１と係止するフランジ係止部５（図２８（ｂ））について説明する。 (Flange locking part)
Next, a flange locking portion 5 (FIG. 28 (b)) for locking with the flange portion 41, which is another function of the sealing member 2, will be described.

フランジ係止部５は半径方向外側に突出した突起部５ｂを備えている。この突起部５ｂは、図２８（ｂ）のようなスナップフィット構造を有し、上述した排出口を形成する内壁１ｂの段差面４１ｂ（図３０）と係止して封止部材２の離間距離を規制するための役割を果たしている。   The flange locking portion 5 is provided with a protruding portion 5b which protrudes outward in the radial direction. The projection 5b has a snap fit structure as shown in FIG. 28 (b), and is engaged with the step surface 41b (FIG. 30) of the inner wall 1b forming the discharge port mentioned above to separate the sealing member 2 Plays a role in regulating the

さらに、このフランジ係止部５はスナップフィット構造であることから、フランジ部４１に対してフランジ係止部５を挿入する（図３０矢印Ｂ方向）際はフランジ係止部５が容易に半径方向内側に撓みながら挿入されるためにスムーズに挿入でき、且つ抜けにくい構成になっている。   Furthermore, since the flange locking portion 5 has a snap-fit structure, the flange locking portion 5 can be easily moved in the radial direction when the flange locking portion 5 is inserted into the flange portion 41 (direction of arrow B in FIG. 30). Since it is inserted while being bent inside, it can be inserted smoothly and is configured to be hard to come off.

ここで重要なのは、このようにフランジ係止部５に設けた突起部５ｂ及びフランジ係止部５の構成がスナップフィット構造を有しているという点である。スナップフィットの利点は僅かな段差面４１ｂでもスラスト方向（図３０Ａ方向）に対しては極めて強い係止力を発揮できる点である。したがって、排出口を形成する内壁１ｂのような比較的肉厚の薄いような箇所においても、その肉厚の範囲内で僅かな段差面４１ｂを形成することにより封止部材２とフランジ部４１を係止するために必要な係止力を、スナップフィット構造によって実現できるのである。   The important point here is that the configuration of the projection 5b and the flange locking portion 5 provided in the flange locking portion 5 in this way has a snap fit structure. The advantage of the snap fit is that even a slight step surface 41b can exhibit a very strong locking force in the thrust direction (the direction of FIG. 30A). Therefore, even at a relatively thin portion such as the inner wall 1b forming the discharge port, the sealing member 2 and the flange portion 41 can be formed by forming a slight step surface 41b within the thickness range. The locking force necessary for locking can be realized by the snap fit structure.

以上説明してきたような封止部材２はプラスチック等の樹脂を射出成型して製造するのが好ましいが、他の材料及び製造方法であっても、任意に分割、接合しても構わない。また、排出口１ａに圧入嵌合してこれを密封する機能が要求されるため、適度な強度と弾性が必要とされる。   The sealing member 2 as described above is preferably manufactured by injection molding of a resin such as plastic, but it may be divided and joined arbitrarily using other materials and manufacturing methods. In addition, since the function of press-fitting and sealing the discharge port 1a is required, appropriate strength and elasticity are required.

そのような材料としては低密度ポリエチレン、ポリプロピレン、直鎖状ポリアミド、例えば商品名ナイロン、高密度ポリエチレン、ポリエステル、ＡＢＳ（アクリロニトリルブタジエンスチレン共重合体）、ＨＩＰＳ（耐衝撃性ポリスチレン）等が好ましく利用できる。   As such materials, low density polyethylene, polypropylene, linear polyamide, such as nylon, high density polyethylene, polyester, ABS (acrylonitrile butadiene styrene copolymer), HIPS (high impact polystyrene), etc. can be preferably used. .

また、シール部のみをエラストマーなどの比較的軟らかい材料にし、封止部材２を先に述べたような樹脂材料にして２色成形するということも、もちろん可能である。このような構成にすると、シール部が軟らかいエラストマーなので密着性が高まりより良いシール性が得られることと、封止部材２の開封時の力を低減でき、より好ましい。尚、実施例２においては封止部材２本体をＡＢＳ樹脂、シール部２ａのみをエラストマーとした２色成形した例を示している。   Further, it is of course possible to make only the seal portion be a relatively soft material such as an elastomer, and to make the sealing member 2 a resin material as described above and perform two-color molding. With such a configuration, since the seal portion is a soft elastomer, the adhesion is enhanced and a better sealability can be obtained, and the force at the time of opening the sealing member 2 can be reduced, which is more preferable. In the second embodiment, an example is shown in which the main body of the sealing member 2 is molded in two colors using the ABS resin and only the sealing portion 2a as an elastomer.

（現像剤補給容器の挿入動作）
図２６、図２７（ａ）〜図２７（ｃ）、図３０を用いて実施例２における現像剤補給容器１の挿入動作について説明する。 (Insertion operation of developer supply container)
The insertion operation of the developer supply container 1 according to the second embodiment will be described with reference to FIGS. 26, 27 (a) to 27 (c), and 30.

図２６に示すように、現像剤受入れ装置２００には、現像剤補給容器１と連結して封止部材２を開閉する封止部材係合部２０が具備されている。封止部材係合部２０は不図示のベアリング等によって回転可能に支持され、現像剤受入れ装置２００内に設けた不図示の駆動機構により、矢印Ａ方向もしくは矢印Ｂ方向にスライドする構成になっている。   As shown in FIG. 26, the developer receiving device 200 is provided with a sealing member engaging portion 20 which is connected to the developer supply container 1 to open and close the sealing member 2. The sealing member engaging portion 20 is rotatably supported by a bearing or the like (not shown), and is configured to slide in the arrow A direction or the arrow B direction by a driving mechanism (not shown) provided in the developer receiving device 200. There is.

図２７（ａ）には、現像剤補給容器１を現像剤受入れ装置２００に矢印Ａ方向へ挿入している途中の状態が示されている。この時点ではまだ、排出口１ａ（図３０参照）は封止部材２により封止された状態にある。   FIG. 27A shows a state in which the developer supply container 1 is being inserted into the developer receiving device 200 in the direction of the arrow A. FIG. At this time, the outlet 1a (see FIG. 30) is still sealed by the sealing member 2.

図２７（ｂ）には、現像剤補給容器１の挿入が更に矢印Ａ方向へ進み、封止部材２に設けた係合突起３（図２８（ｂ））が封止部材係合部２０に係止（抜け止め）された状態が示されている。係合突起３と封止部材係合部２０の係止方法については上述しているため、ここでは省略する。   In FIG. 27B, the insertion of the developer supply container 1 further proceeds in the direction of the arrow A, and the engaging projection 3 (FIG. 28B) provided on the sealing member 2 forms the sealing member engaging portion 20. The locked (retained) state is shown. The locking method of the engaging projection 3 and the sealing member engaging portion 20 has been described above, and therefore, is omitted here.

この時、封止部材２は、係合突起３に設けた係止部としての係止面３ｂ（図２８（ａ））が被係止部としての係止穴２０ｈ（図３０）にスラスト方向（図３０軸Ｐ方向）に係止されているため、この係止を解除しない限り、封止部材２は封止部材係合部２０に固定された状態にある（多少のガタがあっても良い）。   At this time, in the sealing member 2, the locking surface 3 b (FIG. 28 (a)) as a locking portion provided on the engaging projection 3 is thrust in the thrust direction to the locking hole 20 h (FIG. 30) as a locked portion. The sealing member 2 is fixed to the sealing member engaging portion 20 unless it is released because the locking is performed in the direction of the axis P (FIG. 30). good).

図２７（ｃ）は、封止部材２と封止部材係合部２０が係合した後、封止部材２がフランジ部４１（図３０）から相対的に離れて排出口１ａ（図３０）が開き、現像剤補給が可能となった状態が示されている。   In FIG. 27C, after the sealing member 2 and the sealing member engaging portion 20 are engaged, the sealing member 2 is relatively separated from the flange portion 41 (FIG. 30) and the discharge port 1a (FIG. 30) Is open, indicating that the developer can be replenished.

この状態での駆動モータ（図２６）を駆動させると、回転駆動力は、駆動ギア２５から駆動受け部１Ａ５へと伝達され、現像剤補給容器１が回転し、現像剤を搬送、排出する構成になっている。尚、封止部材２はフランジ部４１に対して空回転する構成になっている。   When the drive motor (FIG. 26) in this state is driven, the rotational drive force is transmitted from the drive gear 25 to the drive receiving portion 1A5, the developer supply container 1 is rotated, and the developer is transported and discharged. It has become. The sealing member 2 is configured to rotate idle with respect to the flange portion 41.

また、図２７（ｃ）において、現像剤補給容器１は現像剤受入れ装置２００に設けられたボトル受けローラ２３と回転振れ規制部１Ａ４の当接により回転可能に支持されているため、わずかな駆動トルクでもスムーズに回転することが可能である。尚、ボトル受けローラ２３は現像剤受入れ装置２００に回転自在に設けてある。上述したように、現像剤補給容器１の内部に収容されている現像剤が排出口１ａ（図３０）から順次排出されることで、現像剤は現像剤ホッパ部２０１ａ（図２７）に一時的に貯留され、さらにスクリュー部材２７（図２７）により現像器２０１ｂ（図１）へ搬送され、現像剤補給が行われる。以上が、現像剤補給容器１の挿入動作である。   Further, in FIG. 27C, since the developer supply container 1 is rotatably supported by the contact between the bottle receiving roller 23 provided in the developer receiving device 200 and the rotational runout restricting portion 1A4, slight driving is performed. Even torque can rotate smoothly. The bottle receiving roller 23 is rotatably provided in the developer receiving device 200. As described above, the developer stored in the developer supply container 1 is sequentially discharged from the discharge port 1a (FIG. 30), so that the developer is temporarily stored in the developer hopper portion 201a (FIG. 27). In addition, the developer is transported to the developing device 201b (FIG. 1) by the screw member 27 (FIG. 27), and the developer is replenished. The above is the insertion operation of the developer supply container 1.

（現像剤補給容器の交換動作）
次に、現像剤補給容器１の交換動作について説明する。画像形成のプロセスに伴い、現像剤補給容器１内の現像剤が略全量消費されると、現像剤受入れ装置２００に設けられた現像剤補給容器空検知手段（不図示）によって現像剤補給容器１内の現像剤が無くなったことが検知される。そして、その旨が液晶等の表示手段１００ｂ（図３）によりユーザーに知らされる。 (Developer supply container replacement operation)
Next, the operation of replacing the developer supply container 1 will be described. When the entire amount of the developer in the developer supply container 1 is consumed along with the process of image formation, the developer supply container 1 is provided by the developer supply container empty detection means (not shown) provided in the developer receiving device 200. It is detected that the developer inside has been exhausted. And that is notified to the user by the display means 100b (FIG. 3) such as liquid crystal.

現像剤補給容器１の交換はユーザー自身が行い、その手順は以下の通りである。   The replacement of the developer supply container 1 is performed by the user, and the procedure is as follows.

まず、閉じられた状態の交換用前カバー１５を図３の位置まで開く。次に、現像剤受入れ装置２００の制御によって封止部材係合部２０を矢印Ｂ方向（図２７）にスライドさせ、封止部材係合部２０のスライド動作に伴い、図２７（ｃ）の状態にある封止部材２は矢印Ｂ方向（図２７）へスライドする。すると、排出口１ａを開放する状態にあった封止部材２が排出口１ａに圧入嵌合され、排出口１ａが閉止されることで、上記図２７（ｂ）に示す状態となる。このとき、封止部材２は封止部材係合部２０と係止状態を維持している。   First, the replacement front cover 15 in the closed state is opened to the position shown in FIG. Next, the sealing member engaging portion 20 is slid in the direction of arrow B (FIG. 27) under the control of the developer receiving device 200, and the state of FIG. 27 (c) is accompanied by the sliding operation of the sealing member engaging portion 20. The sealing member 2 located on the side slides in the direction of arrow B (FIG. 27). Then, the sealing member 2 in the state of opening the discharge port 1a is press-fit fitted to the discharge port 1a, and the discharge port 1a is closed, resulting in the state shown in FIG. 27 (b). At this time, the sealing member 2 is maintained in a locked state with the sealing member engaging portion 20.

次に、現像剤受入れ装置２００の制御により、解除部材２１（図３０）が矢印Ｂ方向（図２７）にスライドする。解除部材２１のスライドが進むと、やがて、解除部材２１の内面が解除突起４を半径方向内側に押圧し始める。すると、弾性変形部２ｃが半径方向内側に撓むことにより、封止部材２と封止部材係合部２０の係止が解除される。   Next, under the control of the developer receiving apparatus 200, the release member 21 (FIG. 30) slides in the direction of arrow B (FIG. 27). As the slide of the release member 21 progresses, the inner surface of the release member 21 begins to press the release projection 4 radially inward. Then, the elastic deformation portion 2c is bent inward in the radial direction, whereby the locking of the sealing member 2 and the sealing member engaging portion 20 is released.

次にユーザーは、現像剤受入れ装置２００との係止が解除された空の現像剤補給容器１を矢印Ｂ（図２７）方向に引き出し、現像剤受入れ装置２００から取り出す。この後、ユーザーは新しい現像剤補給容器１を現像剤受入れ装置２００に矢印Ａ方向へ挿入し（図２７（ｂ））、交換用前カバー１５を閉じる。そして、上述のように現像剤排出口開閉手段により封止部材係合部２０に係止された状態の封止部材２が現像剤補給容器１から離間され、排出口１ａが開口される（図２７（ｃ））。以上が、トナー補給容器の交換手順である。   Next, the user pulls out the empty developer supply container 1 whose locking with the developer receiving device 200 has been released in the direction of arrow B (FIG. 27), and takes it out of the developer receiving device 200. Thereafter, the user inserts a new developer supply container 1 into the developer receiving device 200 in the direction of arrow A (FIG. 27 (b)), and closes the front cover 15 for replacement. Then, the sealing member 2 in the state of being locked to the sealing member engaging portion 20 by the developer discharge port opening / closing means as described above is separated from the developer supply container 1 and the discharge port 1a is opened (see FIG. 27 (c). The above is the replacement procedure of the toner supply container.

〔現像剤受入れ装置による現像剤補給制御〕
実施例２における現像剤受入れ装置２００による現像剤補給制御は実施例１と同様であるため、省略する。 [Developer supply control by developer receiving device]
The developer replenishment control by the developer receiving apparatus 200 in the second embodiment is the same as that in the first embodiment, and thus will be omitted.

〔補給精度、画質、回転駆動負荷の比較〕
次に、比較例２、変形例６〜１０、実施例２（図３１）の補給精度、画質、回転駆動負荷の比較について説明する。ここでは、本発明の作用効果を最もよく表す駆動受け部１Ａ５、回転振れ規制部１Ａ４、位相検知部１Ａ６の配置の違いによる補給精度、画質、回転駆動負荷の優劣を比較した。実施例２では、実施例１のカム溝１Ａ３が省かれている。尚、図３１は実施例２の部分拡大図を示している。 [Comparison of supply accuracy, image quality, rotational drive load]
Next, comparison of the replenishment accuracy, the image quality, and the rotational driving load in Comparative Example 2, Modified Examples 6 to 10, and Example 2 (FIG. 31) will be described. Here, the superiority or inferiority of the replenishment accuracy, the image quality, and the rotational driving load due to the difference in the arrangement of the drive receiving portion 1A5, the rotational shake regulating portion 1A4 and the phase detecting portion 1A6 which best show the function and effect of the present invention are compared. In the second embodiment, the cam groove 1A3 of the first embodiment is omitted. FIG. 31 shows a partially enlarged view of the second embodiment.

表２は各構成の違いによる、現像剤補給時における現像剤補給容器１の「補給精度」、「画質」、「回転駆動負荷」を検証した結果を示す。   Table 2 shows the results of verification of “resupply accuracy”, “image quality”, and “rotational driving load” of the developer supply container 1 at the time of developer replenishment due to the difference in each configuration.

Figure 0006532498
Figure 0006532498

なお、表２中の数値と記号の意味は、以下の通りである。   The meanings of the numerical values and symbols in Table 2 are as follows.

補給精度２０％は、目標値±２０％の補給精度である。位相検知部と回転振れ規制部が隣接して配置され、位相検知部の回転振れ起因による振動を規制することで、位相検知フラグ６２と位相検知センサ６１の検知精度が向上する。その結果、トナー排出時にバッフル部材４０の位相決めが精確に行われるため、補給精度の向上ができる。   Supply accuracy 20% is the supply accuracy of the target value ± 20%. The detection accuracy of the phase detection flag 62 and the phase detection sensor 61 is improved by arranging the phase detection unit and the rotational shake restriction unit adjacent to each other and restricting the vibration caused by the rotational shake of the phase detection unit. As a result, since the phase determination of the baffle member 40 is accurately performed at the time of toner discharge, the replenishment accuracy can be improved.

補給精度３０％は、目標値±３０％の補給精度である。補給精度２０％の場合同様、回転振れ規制部により位相検知部の回転振れ起因による振動を規制することができ、補給精度の向上ができる。しかし、位相検知部と回転振れ規制部が隣接して配置されていないため、補給精度２０％と比較すると、振動規制効果が低く、補給精度が劣ってしまう。   The supply accuracy of 30% is the supply accuracy of the target value ± 30%. Similarly to the case of the replenishment accuracy of 20%, the rotation deflection regulating unit can regulate the vibration caused by the rotation deflection of the phase detection unit, and the replenishment accuracy can be improved. However, since the phase detection unit and the rotational runout regulation unit are not arranged adjacent to each other, the vibration regulation effect is low and the replenishment accuracy is inferior as compared to the replenishment accuracy of 20%.

補給精度４０％は、目標値±４０％の補給精度である。回転振れ規制部を設けていないため、位相検知部の回転振れ起因による振動によって、補給精度３０％と比較すると補給精度が劣ってしまう。   Supply accuracy 40% is the target value ± 40% supply accuracy. Since the rotational runout restricting portion is not provided, the vibration due to the rotational runout of the phase detection portion causes the replenishment accuracy to be inferior as compared to the replenishment accuracy of 30%.

画質◎は、駆動受け部と回転振れ規制部が隣接して配置され、駆動受け部の回転振れ起因による振動を規制することができ、駆動伝達が向上するため、画質の向上ができる。   In the image quality ◎, the drive receiving portion and the rotational shake restricting portion are arranged adjacent to each other, so that the vibration due to the rotational shake of the drive receiving portion can be restricted, and the drive transmission is improved, so the image quality can be improved.

画質○は、◎の場合同様、回転振れ規制部により駆動受け部の回転振れ起因による振動を規制することができ、回転駆動伝達が向上するため、画質の向上が期待できる。しかし、駆動受け部と回転振れ規制部が隣接して配置されていないため、◎と比較すると振動規制効果が低く、画質が劣ってしまう。   Similarly to the case of ◎, in the case of は, the rotation shake restricting portion can restrict the vibration due to the rotation shake of the drive receiving portion, and the rotation drive transmission is improved, so the improvement of the image quality can be expected. However, since the drive receiving portion and the rotational shake restricting portion are not arranged adjacent to each other, the vibration restricting effect is low compared to ◎, and the image quality is degraded.

画質△は、回転振れ規制部を設けていないため、駆動受け部の回転振れ起因による振動によって、○と比較すると画質が劣ってしまう。   The image quality Δ is inferior to the image quality as compared with O due to the vibration caused by the rotational shake of the drive receiving portion, since the rotational shake restriction portion is not provided.

フランジ部４１に設けられる位相検知部１Ａ６、回転振れ規制部１Ａ４、駆動受け部１Ａ５は、現像剤補給容器１を現像剤受入れ装置２００へ挿入する際、現像剤受入れ装置２００に設けられる位相検知フラグ６２、ボトル受けローラ２３、駆動ギア２５と当接または噛み合う構成である（図３１）。したがって、現像剤補給容器１を現像剤受入れ装置２００へ挿入する際のユーザーの操作性を考慮すると、「位相検知部（被検知部）」、「回転振れ規制部（当接部）」、「駆動受け部」の周方向外形は容器挿入方向下流側から徐々に大きくなる配置構成が望ましい。よって、「位相検知部」、「回転振れ規制部」、「駆動受け部」の配置構成で駆動受け部の周方向外形が制限されるため、現像剤補給容器１が回転する際の駆動負荷に影響する。以下に「位相検知部」、「回転振れ規制部」、「駆動受け部」の配置構成の違いによる駆動負荷への影響と表２の記号の意味を説明する。   The phase detection unit 1A6, the rotational shake regulation unit 1A4, and the drive reception unit 1A5 provided in the flange unit 41 are phase detection flags provided in the developer receiving device 200 when the developer supply container 1 is inserted into the developer receiving device 200. 62, the bottle receiving roller 23, and the drive gear 25 are in contact or meshed (FIG. 31). Therefore, in consideration of the operability of the user when inserting the developer supply container 1 into the developer receiving apparatus 200, "phase detection portion (detected portion)", "rotational shake regulation portion (contact portion)", "phase detection portion" The circumferential configuration of the drive receiving portion is desirably arranged so as to gradually increase from the downstream side in the container insertion direction. Accordingly, the circumferential configuration of the drive receiving portion is limited by the arrangement configuration of the “phase detection portion”, “rotational runout restricting portion”, and “drive receiving portion”, so that the driving load when the developer supply container 1 rotates. Affect. The influence on the drive load due to the difference in the arrangement configuration of the “phase detection unit”, the “rotational shake regulation unit”, and the “drive receiving unit” will be described below and the meaning of the symbols in Table 2 will be described.

回転駆動負荷◎は、「位相検知部」、「回転振れ規制部」、「駆動受け部」のうち、駆動受け部が容器挿入方向最上流側に配置されることで、駆動受け部の外径を１番大きくすることができるため、回転駆動負荷を最も小さくすることができる。   The rotational drive load ◎ is the outer diameter of the drive receiving portion by disposing the drive receiving portion on the most upstream side in the container insertion direction among the “phase detection portion”, “rotational runout restricting portion”, and “drive receiving portion”. Can be made the largest, so the rotational drive load can be made the smallest.

回転駆動負荷○は、「位相検知部」、「回転振れ規制部」、「駆動受け部」のうち、駆動受け部が容器挿入方向上流側から２番目に配置されることで、駆動受け部の外径を２番目に大きくすることができるため、駆動受け部の回転駆動負荷を小さくすることができるが、◎と比べると回転駆動負荷が大きくなる。   The rotational drive load ○ is a drive reception unit of the “phase detection unit”, the “rotational shake regulation unit”, and the “drive reception unit”, which is disposed second from the upstream side in the container insertion direction. Since the outer diameter can be increased to the second, the rotational drive load of the drive receiving portion can be reduced, but the rotational drive load becomes larger compared to ◎.

回転駆動負荷△は、「位相検知部」、「回転振れ規制部」、「駆動受け部」のうち、駆動受け部が容器挿入方向上流側から３番目に配置されることで、駆動受け部の外径が最も小さくなるため、○と比較すると回転駆動負荷が大きくなってしまう。   The rotational drive load Δ is the drive reception unit of the “phase detection unit”, the “rotational runout regulation unit”, and the “drive reception unit”, which is disposed third from the upstream side in the container insertion direction. Since the outer diameter is the smallest, the rotational drive load will be large compared to ○.

比較例２について説明する（不図示）。比較例２はフランジ部４１に設けられる駆動受け部１Ａ５、位相検知部１Ａ６と（回転振れ規制部１Ａ４はなし）、駆動ギア２５、位相検知フラグ６２、位相検知センサ６１、ボトル受けローラ２３の配置が実施例２とは異なっており、その他の構成は実施例２と同様である。具体的には、現像剤補給容器１の挿入方向下流側からカム溝１Ａ３、位相検知部１Ａ６、駆動受け部１Ａ５の順に並ぶ配置である。 (Comparative example 2)
Comparative Example 2 will be described (not shown). In Comparative Example 2, the arrangement of the drive receiving portion 1A5, the phase detection portion 1A6 and the rotation detection restricting portion 1A4 provided in the flange portion 41, the drive gear 25, the phase detection flag 62, the phase detection sensor 61, and the bottle receiving roller 23 The configuration is different from that of the second embodiment, and the other configuration is the same as that of the second embodiment. Specifically, the cam groove 1A3, the phase detection unit 1A6, and the drive receiving unit 1A5 are arranged in this order from the downstream side of the developer supply container 1 in the insertion direction.

この配置だと、回転振れ規制部を設けていないため、位相検知部の回転振れ起因による振動によって補給精度が悪くなり、おおよそ目標値±４０％の補給精度となる。   In this arrangement, since the rotational runout regulating unit is not provided, the replenishment accuracy deteriorates due to the vibration caused by the rotational runout of the phase detection unit, and the replenishment accuracy becomes approximately the target value ± 40%.

画質に関しては、回転振れ規制部を設けていないため、回転振れ規制部を設けた場合と比較すると、駆動受け部の回転振れ起因による振動によって画質が劣ってしまう。   As for the image quality, since the rotational runout regulating unit is not provided, the image quality is degraded due to the vibration caused by the rotational runout of the drive receiving portion as compared with the case where the rotational runout regulating unit is provided.

回転駆動負荷に関しては、駆動受け部が容器挿入方向最上流側に配置されることで駆動受け部の外径を１番大きくすることができるため、回転駆動負荷を最も小さくすることができる。   With regard to the rotational drive load, the outer diameter of the drive receiving portion can be made as large as possible by arranging the drive receiving portion on the most upstream side in the container insertion direction, so the rotational driving load can be minimized.

Also, it is possible to expect improvement in the supply accuracy, and the supply accuracy is approximately the target value ± 20%.

Detection accuracy is improved. As a result, since the phasing of the baffle member 40 is accurately performed at the time of toner discharge, the replenishment accuracy can be improved more than Comparative Example 2 in which the rotational runout regulating portion 1A4 is not provided, and the replenishment accuracy of approximately target value ± 20% Become.

画質に関しては、駆動受け部と回転振れ規制部を隣接して配置することで、駆動受け部の回転振れ起因による振動を効率よく規制することができ、駆動伝達が向上し、回転振れ規制部１Ａ４を設けていない比較例２よりも画質の向上が期待できる。   With regard to the image quality, by arranging the drive receiving portion and the rotational shake restricting portion adjacent to each other, it is possible to efficiently regulate the vibration due to the rotational shake of the drive receiving portion, and the drive transmission is improved. The improvement of the image quality can be expected as compared with Comparative Example 2 in which is not provided.

以上より、最も好適な構成は容器挿入方向下流側から位相検知部１Ａ６、回転振れ規制部１Ａ４、駆動受け部１Ａ５と配置する構成、つまり「実施例２」の構成である。   As described above, the most preferable configuration is the configuration in which the phase detection unit 1A6, the rotational shake regulation unit 1A4, and the drive receiving unit 1A5 are disposed from the downstream side in the container insertion direction, that is, the configuration of “second embodiment”.

本実施例によっても、前述した実施例と同様に、現像剤補給時における現像剤補給容器の回転振れを回転振れ規制部で規制することによって、位相検知部と駆動受け部の双方の回転振れを低減できる。その結果、駆動伝達と位相検知の双方の精度向上ができる。さらに、現像剤補給容器の回転による振動も低減できるため、画質の向上ができる。   Also in this embodiment, as in the above-described embodiment, the rotational runout of the developer supply container during developer replenishment is regulated by the rotational runout regulating unit, so that the rotational runout of both the phase detection unit and the drive receiving unit It can be reduced. As a result, the accuracy of both drive transmission and phase detection can be improved. Furthermore, since the vibration due to the rotation of the developer supply container can also be reduced, the image quality can be improved.

〔他の実施例〕
前述した実施例では、位相検知部１Ａ６が凹部（又は凸部）である構成を例示したが、これに限定されない。例えば、図３２に示すように、位相検知部１Ａ６を回転振れ規制部１Ａ４と同じ面上に設けた銀紙などの反射面とする構成でも良い。この構成の場合、位相検知部１Ａ６を検知する装置側の位相検知センサ６３を光学センサとする。このように構成しても、前述した実施例と同様の効果が得られる。 Other Embodiments
In the above-described embodiment, the configuration in which the phase detection unit 1A6 is the concave portion (or the convex portion) is exemplified, but the invention is not limited thereto. For example, as shown in FIG. 32, the phase detection unit 1A6 may be configured to be a reflective surface such as silver paper provided on the same surface as the rotational shake restriction unit 1A4. In this configuration, the phase detection sensor 63 on the device side that detects the phase detection unit 1A6 is an optical sensor. Even with this configuration, the same effect as the above-described embodiment can be obtained.

また前述した実施例では、画像形成装置としてプリンタを例示したが、本発明はこれに限定されるものではない。例えば複写機、ファクシミリ装置等の他の画像形成装置や、或いはこれらの機能を組み合わせた複合機等の他の画像形成装置であっても良い。これらの画像形成装置に用いられる現像剤補給容器或いは現像剤補給システムに本発明を適用することにより同様の効果を得ることができる。   In the above-described embodiment, the printer is exemplified as the image forming apparatus, but the present invention is not limited to this. For example, it may be another image forming apparatus such as a copying machine or a facsimile machine, or another image forming apparatus such as a complex machine combining these functions. The same effects can be obtained by applying the present invention to a developer supply container or a developer supply system used in these image forming apparatuses.
