PROBLEM TO BE SOLVED: To obtain a structure preventing image deletion and image blurring in a structure that excels in economical efficiency, makes FCOT short and suppresses enlargement of an apparatus.SOLUTION: A shutter member 18 which is wound up is arranged between a charger 2 and a photoreceptor drum 1. The shutter member 18 includes a second sheet section 20b and a third sheet section 20c and winding up is made possible by a winding up means 22 from a connecting section of both sheet sections 20b and 20c through a first sheet section 20a. Surfaces of both sheet sections 20b, 20c are opposed to a charger 2 side in a shut state and wound up so that surfaces of both the sheet sections 20b, 20c are overlapped in an evaded state. Thus, the surface on the charger 2 side of the shutter member 18 does not come into contact with the surface of the photoreceptor drum 1 side even in the evaded state. |
