摘要

A cleaning device 70 includes: contact and release system 63 which switches a position of a cleaning roller between a position where the cleaning roller 62 is in contact with a charging roller 61 and a position where the cleaning roller 62 is separated from the charging roller 61; and a voltage selecting section 71 which switches a voltage to be applied to the charging roller 61 from a DC voltage to an AC voltage during the rotation of a photoreceptor 11. The contact and release system 63 brings the cleaning roller 62 into contact with the charging roller 61 at the application of the AC voltage to the charging roller 61. This makes it possible to enhance performance on cleaning of the charging roller.
