<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus in which a developing device unit can be attached to/detached from an apparatus body with a simple mechanism. <P>SOLUTION: A color multifunctional system 1 includes: a photoreceptor unit 30 including a plurality of photoreceptor drums 32; and a developing device unit 40 which includes a plurality of developing cartridges 42 provided corresponding to the plurality of photoreceptor drums 32 and including developing rollers, and a support member 41 supporting the plurality of developing cartridges 42, and is attachable to/detachable by drawing it from a body case 2 in an arrangement direction of the plurality of photoreceptor drums 32. Each of the plurality of developing cartridges 42 is movably supported in the support member 41 between a developing position in which the developing roller is close to the photoreceptor drum 32 and an attachment/detachment position in which the developing roller is separated from the photoreceptor drum 32 more than the developing position and can be attached to/detached from the body case 2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
