<P>PROBLEM TO BE SOLVED: To provide a photoreceptor unit which is downsized in a configuration that constitution where a plurality of cartridges are attached to a frame in the state of being arranged side by side, and to provide an image forming apparatus with the photoreceptor unit. <P>SOLUTION: A drawer unit 21 of a process unit 20 includes: a pair of side plates 22 supporting a photoreceptor drum 3; and a beam member 38 laid between the pair of side plates 22. A guide groove 27 for guiding a developing roller 5 of a developing cartridge 6 is formed on the side plate 22. The guide groove 27 includes at least a first portion 27A and a second portion 27B extending in a direction crossing the first portion 27A. While the developing cartridge 6 is attached to the drawer unit 21, a lower rear wall 38D of the beam member 38 is opposed to a lower front wall 55B of the developing cartridge 6, and an upper rear wall 38E of the beam member 38 is opposed to an upper front wall 55C of the developing cartridge 6. <P>COPYRIGHT: (C)2010,JPO&INPIT |
