<p>PROBLEM TO BE SOLVED: To prevent jamming processing from becoming troublesome because jammed paper enters the inside of an image formation device by butting the jammed paper on the jammed paper butting part of a protective member and preventing it from entering when the jammed paper is returned from the side of a fixing device at the time of the jamming processing. SOLUTION: A shutter (the protective member) 25 is provided freely movably between a protective position where the photoreceptor 11 is covered and a nonprotective position where it is exposed at the image formation device A where the photoreceptor 11 is integrally provided with an electrifier 12 or the like. The shutter 25 is made long plate-like in the axial direction of the photoreceptor, and one side is bent and raised, so that the first and second butting parts 25c and 25d for the jammed paper S are provided. When the shutter 25 is at the protective position at the time of returning the jammed paper S from the side of the fixing device 16 at the time of the jamming processing, the rear end of the jammed paper S butts on the first butting part 25c of a jammed paper butting part 25b, and when the shutter 25 is at the nonprotective position, it butts on the second butting part 25d, so that the jammed paper S is prevented from entering the inside of the image formation device A.</p> |
