ABSTRACT:
A lubricant for reducing friction produced between a cleaning device and a photoconductor both assembled in a copying apparatus includes an abrasive agent having an average grain diameter of 0.5 .mu.m to 9.0 .mu.m. The abrasive agent comprises a main chemical component of material which does not change the developing characteristics of a developer used in an electrostatic copying process and which refines the scratches produced on the surface of the photoconductor due to the contact between the developer and the photoconductor during a long period of time.
