ABSTRACT:
A cleaning device for a photoelectrostatic copying apparatus has a cleaning blade and a cleaning roller adapted to be brought into pressing engagement with a photosensitive member to effect cleaning thereof after transfer printing. The cleaning blade is brought out of contact with the photosensitive member and the cleaning roller is either brought out of contact with the photosensitive member or has its contact pressure reduced when the apparatus is inoperative, whereby damage to the photosensitive member due to the pressing engagement of the photosensitive member with the blade and the roller can be avoided or minimized.
