Patent ID: 7239823

Claim:
A process cartridge detachably mountable on an apparatus main body of an electrophotographic image forming apparatus for forming an image on a recording material, said process cartridge comprising: an electrophotographic photosensitive drum; a developing roller, which develops an electrostatic latent image formed on said electrophotographic photosensitive drum; a driving force receiving portion, which receives from the apparatus main body a driving force for rotating said electrophotographic photosensitive drum in a state in which said process cartridge is mounted on the apparatus main body, said driving force receiving portion being disposed on one end portion of said process cartridge in a longitudinal direction thereof; a developing bias contact, which receives from the apparatus main body a developing bias to be applied to said developing roller in the state in which said process cartridge is mounted on the apparatus main body, said developing bias contact being disposed on the other end portion of said process cartridge in the longitudinal direction thereof; a first cartridge guide to be guided by a first main body guide disposed in the apparatus main body when said process cartridge enters the apparatus main body, said first cartridge guide to be guided being disposed at said one end portion of said process cartridge; and guiding means for being guided by a second main body guide disposed in the apparatus main body when said process cartridge enters the apparatus main body, said guiding means being disposed at the other end portion of said process cartridge in the longitudinal direction thereof, said guiding means comprising means for moving a grounded electrically conductive member disposed in the apparatus main body from a position in an entry route, along which said process cartridge enters the apparatus main body, to a position out of the entry route when said process cartridge enters the apparatus main body by being brought into contact with a first abutting portion of an actuating member disposed in the apparatus main body when said process cartridge enters the apparatus main body, and for moving the grounded electrically conductive member from the position out of the entry route to the position in the entry route when said process cartridge is removed from the apparatus main body by being brought into contact with a second abutting portion of the actuating member when said process cartridge is removed from the apparatus main body.
