摘要：
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes (a) a developing unit for supporting an electrophotographic photosensitive drum and a developing member for developing an electrostatic latent image formed on the electrophotographic photosensitive drum with a developer; (b) a charging unit for supporting a charging member for charging the electrophotographic photosensitive drum, the charging unit being rotatable in a first rotational direction about a rotational center relative to the developing unit in which the charging member moves toward the electrophotographic photosensitive drum and in a second rotational direction about the rotational center in which the charging member moves away from the electrophotographic photosensitive drum.
