ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE

摘要

An electrophotographic photosensitive member is provided which maintains excellent smoothness of the surface thereof and improves cleaning performance during long-term repeated use, and which suppresses blade chattering and turn-up, thereby providing good image reproduction, and a process cartridge and electrophotographic apparatus having the electrophotographic photosensitive member are provided. The electrophotographic photosensitive member has a photosensitive layer formed on a support. The electrophotographic photosensitive member has a surface layer containing a silicon-containing compound or a fluorine-containing compound. The surface layer has a plurality of depressed portions which are independent from one another, on the surface. When the major axis diameter of the depressed portion is represented by Rpc and the distance between the deepest part and the opening surface of the depressed portion is represented by Rdv, Rdv is 0.1 µ or more to 10.0 µm or less, and the ratio of the depth (Rdv) to the major axis diameter (Rpc), Rdv/Rpc, is more than 0.3 to 7.0 or less.
