<P>PROBLEM TO BE SOLVED: To reduce a space capacity of the first and second shutter members at the saving position by allowing first and second shutter members to overlap each other to be turnable to a saving position. <P>SOLUTION: A photoreceptor unit 20 having a photoreceptor drum 21 and a developing unit 40 having a developing sleeve 41 are disposed attachably and detachably on an image forming apparatus body 2, wherein the photoreceptor unit 20 has a shutter member which is turnably disposed from a shielding position to the saving position of the photoreceptor drum 21. The shutter member has the first shutter member 23 with which the lower side of the photoreceptor drum 21 is covered and the second shutter member 24 with which the opposite side 2A of the photoreceptor drum 21 and the developing sleeve 41 is covered in a state in which the photoreceptor unit 20 is detached from the image forming apparatus body 2. The first shutter member 23 overlaps the second shutter member 24 in the course of turning from the shielding position to the saving position and is integrally turned to the saving position. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
