Abstract

A cleaning device includes a cleaning roll and an intervening member. The cleaning roll contacts the surface of a charge roll that charges a photoconductor, rotates, and cleans the surface of the charge roll. The intervening member is intervened between the charge roll and the cleaning roll and causes the charge roll and the cleaning roll to separate from each other. The intervening member may be spacers that are intervened at both end portions of the charge roll and the cleaning roll and form a gap between the charge roll and the cleaning roll. The intervening member may also be a lubricant.
