ABSTRACT:
Provided is an electrophotographic photosensitive member in which friction memory does not easily occur, and a process cartridge and an electrophotographic apparatus which have the electrophotographic photosensitive member. The electrophotographic photosensitive member having a photosensitive layer has a surface layer having a plurality of depressed portions which are independent from one another, where the minor axis diameter of the depressed portions is Rpc and the depth indicating the distance between the innermost part of a depressed portion and the opening surface thereof is Rdv, the depressed portions have a ratio of depth to minor axis diameter (Rdv/Rpc) on a surface of the photosensitive member of 1.0 or less, and the photosensitive layer has a charge transporting material with an ionization potential of 4.5 eV or more and 5.3 eV or less.
