Abstract
A process cartridge includes an image bearing member, a developing device developing an electrostatic image on the member using developer to form a developer image on the member and a developer charger charging residual developer on the member disposed downstream of a transferring position at which the developer image is transferred onto a transfer destination member and upstream of a position at which the electrostatic image is formed on the member with respect to the moving direction of the member. The developer charger is in contact with the member and is movable in the longitudinal direction of the member upon charging the residual developer. Ld≦Lwhen Lis the developing width of the developing device, Lis the contact width of the developer charger with the member, and d is the width of movement of the developer charger in the longitudinal direction of the member.
