摘要:
The present invention provides a cleaning apparatus comprising a cleaning rotary member arranged to be pressed against a movable image bearing member, for removing residual toner on the image bearing member. Cleaning rotary member has a first elastic layer as an outer layer, and a second elastic layer disposed inside of the first elastic layer. Second elastic layer has a volume resistance smaller than that of the first elastic layer. The present invention further provides a cleaning roller comprising a core metal, a conductive layer disposed on the core metal and an insulation layer disposed on the conductive layer.
