ELECTRONIC PHOTOGRAPHING PHOTOSENSITIVE BODY, PROCESS CARTRIDGE, AND ELECTRONIC PHOTOGRAPHING DEVICE

摘要

An electrophotographic photosensitive member improved in cleaning performance and having a good image reproducibility, even in its long-term service, and a process cartridge and an electrophotographic apparatus which have the electrophotographic photosensitive member are provided. The electrophotographic photosensitive member has, on the surface of its photosensitive layer, has a plurality of depressed portions which are independent from one another, and, where the major-axis diameter of each depressed portion is represented by Rpc and the depth that shows the distance between the deepest part of each depressed portion and the opening thereof is represented by Rdv, the depressed portions each have a ratio of depth to major-axis diameter, Rdv/Rpc, of from more than 1.0 to 7.0 or less.
