ABSTRACT:
A charger of a process cartridge may be configured so that a charging wire is laid across an upper frame. An upper frame may be provided with a stopper at which one end of the charging wire is caught, and with a wire pulling member that pulls the charging wire at the other end. The wire pulling member may include a coil spring portion and an engaging portion capable of engaging with the other end of the charging wire, so that the engaging portion may rotate on a centerline of the coil spring portion. The wire pulling member may be held in the upper frame so that the centerline of the coil spring portion may be substantially perpendicular to a longitudinal direction of an extended portion of the charging wire.
