Abstract

PURPOSE:To enhance the stabilization of an image quality, to improve reliability and to scale-down a device by constituting a carrier means including a gear which gears into a rack cut on the lower surface of a developing unit and a motor which drives to rotate the gear. CONSTITUTION:The carrier means M1 and M2 are constituted, including the gears 12 and 14 which gear into the rack 11 cut on the lower surface of the developing unit 2A and the motors 13 and 15 which drive to rotate them. Namely, the carrier means M1 and M2 are provided by superposed on the developing unit on the lower side of the developing unit 2A. And a black developing unit 3 which uses one component type magnetic toner is provided on the upper side and a color developing unit 2A which uses two component type nonmagnetic toner is provided on the lower side. Thus, the lowering of the image density caused by the dark decay of a photosensitive body, the damage of a sleeve and malfunction following the drop of carrier, and also the occurrence of white stripes can be prevented, then the scale-down of the device main body can be possible.
