发明名称 Image forming cartridge and image forming apparatus having a photoreceptor drum that rotates at a constant velocity and is stably grounded
摘要 An image forming cartridge and an image forming apparatus equipped with the image forming cartridge is provided which enables a photoreceptor drum to be surely grounded and costs to be reduced. The image forming cartridge is made up of the photoreceptor drum having conductive members, a conductive drum supporting member being fixed in a manner to contact the conductive member, a gear to be contacted with a driving gear when being placed at the image forming apparatus and to be adapted to transfer rotation from the driving gear to the photoreceptor drum and to produce thrust at a time of transfer of rotation, a drum shaft composed of conductors and contacting a part of inner circumferential face of the drum supporting member, collar composed of conductors and being fitted into the drum shaft and an E ring to position the collar.
