ABSTRACT:
A cleaning apparatus for a copying machine employs a resilient cleaning roller 8 which presses against and forms a nip with the surface of a photosensitive member 1. The roller 8 has a hollow shaft 13 through which a driving shaft 14 is received. Driving force is transmitted to the resilient cleaning roller 8 at the end of the driving shaft 14 which is remote from the end thereof where a driving force is applied. In consequence, the nip between the photosensitive member 1 and the resilient cleaning roller 8 is favorably stabilized. It is therefore possible to minimize the risk of the photosensitive member 1 being damaged and to enhance the effect of the cleaning apparatus in removing charging products which cling to the surface of the photosensitive member. Further, it conveniently becomes unnecessary to effect any delicate adjustment of the position of the cleaning roller 8.
