Patent ID: 6922539

Claim:
A process cartridge detachably attachable to a body of an image forming apparatus, comprising: an image bearing member; a developing device configured and positioned to develop an electrostatic image formed on said image bearing member by using developer to form a developer image on said image bearing member; and a developer charger configured and positioned to charge residual developer on said image bearing member disposed downstream, with respect to a moving direction of said image bearing member, of a transferring position at which said developer image is transferred onto a transfer member and upstream, with respect to the moving direction of said image bearing member, of a position at which the electrostatic image is formed on said image bearing member, said developer charger being disposed to contact said image bearing member, and said developer charger being movable in a direction substantially the same as the longitudinal direction of said image bearing member upon charging said residual developer, wherein in the direction substantially the same as the longitudinal direction of said image bearing member, when L 1 denotes the developing width of said developing device, L 2 denotes the contact width of said developer charger with said image bearing member, and d denotes the width of movement of said developer charger, the following condition is satisfied: L 1 + d≦L 2 .
