PURPOSE:To prevent the contamination with toner and to facilitate assembly, inspection, maintenance, etc. by coupling a photoreceptor, a developing device, a cleaning device, a reducing device and a toner replenishing part into one body, and mounting the assembly drawably to a movable mounting frame. CONSTITUTION:A photoreceptor 1 via bearings, a developing device 2 provided with a magnetic brush 2a, and a cleaning device 3 provided with a scraper blade 3a are mounted to the front and rear side plates of a movable mounting frame 6 in respective casings, and a reducing device 4 provided with a conveying screw 4a, a reducing screw 4b and a distributing screw 4c as well as a toner replenishing part 5 coupled in one body thereto are mounted with the device 3 and the device 2 in the above-mentioned way. The casing in the part of the screw 4b is mounted to the side plate on one side of the frame 6. Thus all the devices from the photoreceptor 1 up to the part 5 are mounted in the frame 6 by maintaining mutual operating relations. |
