ABSTRACT:
Disclosed is an electrophotosensitive member and its preparing method. The electrophotosensitive member comprises an electrically conductive substrate, a photosensitive layer, and an overcoat layer having a rough surface with convexities and concavities. The number of convexities and concavities are about 500 to 3000 per 1 cm in a linear distance, and the maximum depth difference of the convexities and concavities is about 0.05 to 1.5 .mu.m. The rough surface having the convexities and concavities is formed directly on the overcoat layer. The electrophotosensitive member according to the present invention reduces the friction coefficient of the contacting area between the electrophotosensitive member and a cleaning device, and improves the durability of the overcoat layer and the photosensitive layer.
