<P>PROBLEM TO BE SOLVED: To solve such a problem that it is considered that contaminated matter is received by a shutter opening and closing the opening of a corona electrifier, because when the contaminated matter adhering to a grid is dropped onto a photoreceptor by cleaning, adverse effects such as image flowing are made, but in such a configuration that the shutter shielding the opening of the corona electrifier in a longitudinal direction is wound, when the shutter to which the contaminated matter is adhered is wound, the contaminated matter is transferred to the surface on a photoreceptor side of the shutter. <P>SOLUTION: A winding mechanism includes a roll for winding the shutter in such a state that the surface on a grid side of the shutter is turned to the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
