Abstract:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, comprising:(a) a developing unit for supporting an electrophotographic photosensitive drum and a developing member for developing an electrostatic latent image forming on said electrophotographic photosensitive drum with a developer; (b) a charging unit for supporting a charging member for charging said electrophotographic photosensitive drum, said charging unit being rotatable in a first rotational direction about a rotational center relative to said developing unit in which said charging member moves toward said electrophotographic photosensitive drum and in a second rotational direction about the rotational center in which said charging member moves away from said electrophotographic photosensitive drum; and (c) means for rotating said charging unit in a first rotational direction about the rotational center relative to said developing unit in which said charging member moves toward said electrophotographic photosensitive drum and in a second rotational direction about the rotational center in which said charging member moves away from said electrophotographic photosensitive drum; and a stopper for limiting rotation of said charging unit in said first rotational direction beyond a predetermined distance.
