PROBLEM TO BE SOLVED: To provide an image forming cartridge capable of realizing the sure grounding of a photoreceptor drum and the reduction of cost, and an image forming apparatus to which the image forming cartridge is attached. SOLUTION: This image forming cartridge is equipped with the photoreceptor drum 15 equipped with conductive base material, a conductive drum supporting member 48 fixed in a state where it comes into contact with the conductive base material, a gear 51 connected to a driving gear 53 at the time of attaching the cartridge to the image forming device, transmitting rotation from the gear 53 to the drum 15 and generating thrust force to either end side from the other end side as the rotation is transmitted, a drum shaft 16 consisting of a conductor and coming into contact with a part of the inner peripheral surface of the member 48, a collar 49 consisting of a conductor and fit in a drum shaft 16 at a position where it comes into contact with the side surface of the member 48 on an opposite side to a side opposed to the gear 51, and an E ring positioning and fixing the collar 49 energized by the thrust force at a specified position. |
