Electrophotographic photoreceptor, image forming apparatus, and process cartridge

摘要

An electrophotographic photoreceptor includes a substrate and a photosensitive layer, wherein the electrophotographic photoreceptor has a surface layer containing fluorine resin particles, and the fluorine resin particles exposed on a surface satisfy the following Expression (1):
0.5≦(A)/(B)≦10  Expression (1)
wherein, (A) represents a number of aggregated particles in which 5 to 20 fluorine resin particles are connected and aggregated, and (B) represents a total number of fluorine resin particles that are isolated without being aggregated and aggregated particles in which 2 to 4 fluorine resin particles are connected and aggregated.
