本発明は、画像形成装置に用いられるプロセスカートリ
ッジに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a process cartridge used in an image forming apparatus.
従来、この種のプロセスカートリッジは、像担持体、帯
電器、現像器、およびクリーニング手段が一体的に保持
され、プロセスカートリッジに対しては固定されていた
。Conventionally, in this type of process cartridge, an image carrier, a charger, a developer, and a cleaning means are integrally held and fixed to the process cartridge.
上述した従来のプロセスカートリッジは、現像器がプロ
セスカートリッジより着脱不能となっているので、現像
器内部の現像剤が無くなった場合、現像剤の補充が不可
能であり、プロセスカートリッジ全体を交換しなければ
ならず、ランニングコストが高くつくという欠点があっ
た。In the conventional process cartridge described above, the developing device is not removable from the process cartridge, so if the developer inside the developing device runs out, it is impossible to replenish the developer and the entire process cartridge must be replaced. However, it also had the disadvantage of high running costs.
本発明のプロセスカートリッジは、少なくとも像担持体
、帯電器、現像器、およびクリーニング手段を一体的に

いて、前記現像器が現像剤補給口を有し、前記プロセス
カートリッジに対して着脱自在に構成されている。The process cartridge of the present invention integrally includes at least an image bearing member, a charging device, a developing device, and a cleaning means, and is removably attached to an apparatus main body, wherein the developing device has a developer replenishment port; It is configured to be detachable from the process cartridge.
次に、本発明の一実施例について図面を参照して説明す
る。Next, an embodiment of the present invention will be described with reference to the drawings.
第１図は、本発明の一実施例を示す断面図である。像担

脱可能になっている。像担持体ｌは、矢印方向に回転し
ながら以下の一連のプ四セスを受ける。まず、帯電器４
が像担持体１の表面を均一に帯電する。FIG. 1 is a sectional view showing one embodiment of the present invention. The image carrier 1, the developing device 2, the cleaning means 3, and the charger 4 are integrally supported by a support member 8, and are removable from the apparatus main body. The image carrier 1 undergoes the following series of processes while rotating in the direction of the arrow. First, charger 4
charges the surface of the image carrier 1 uniformly.
次に、露光手段（図示せず）により露光され、像担持体
１の表面に潜像が形成される。現像器２は、現像剤７を
像担持体ｌの潜像部に付着せしめ、潜像を可視化する。Next, the image carrier 1 is exposed to light by an exposure means (not shown), and a latent image is formed on the surface of the image carrier 1. The developing device 2 causes the developer 7 to adhere to the latent image portion of the image carrier 1, and visualizes the latent image.
現像された像担持体１は、転写器により転写材上に像を
転写する。転写された像担持体ｌは、クリーニング手段
３により余分の現像剤を除去される。最後に、像担持体
１は、除電器により表面を除電される。The developed image carrier 1 transfers the image onto a transfer material by a transfer device. A cleaning means 3 removes excess developer from the transferred image carrier l. Finally, the surface of the image carrier 1 is neutralized by a static eliminator.
第２図および第３図を参照すると、現像器２は、支持部
材８の支点９と、現像器２の支点１０を、支持ピン１３
により左右で嵌合支持されている。Referring to FIGS. 2 and 3, the developing device 2 connects the fulcrum 9 of the supporting member 8 and the fulcrum 10 of the developing device 2 with a support pin 13.
are fitted and supported on the left and right sides.
支持ピン１３はコイルスプリング１２とビン１１とを有
する。現像器２の内部の現像剤７が消費されると、左右
の支持ピン１３を外側に引出し、現像器２を支持部材８
から取り出す。The support pin 13 has a coil spring 12 and a pin 11. When the developer 7 inside the developing device 2 is consumed, the left and right support pins 13 are pulled out, and the developing device 2 is moved to the support member 8.
Take it out.
次に、現像剤補給口５を閉めているキャップ６を取り外
すことにより、現像剤７の補給が可能となる。Next, by removing the cap 6 that closes the developer supply port 5, the developer 7 can be replenished.
以上説明したように、本発明は現像剤補給口を有する現

るだけでプロセスカートリッジが再使用でき、ランニン
グコストを低減できるという効果がある。As described above, the present invention has a developing device having a developer replenishment port that can be detachably attached to the process cartridge, so that even when the developer in the developing device is consumed, the developing device can be removed from the process cartridge. The process cartridge can be reused simply by replenishing the developer, which has the effect of reducing running costs.
