Abstract

An electrophotographic photosensitive member having excellent electrophotographic properties, a method of manufacturing the electrophotographic photosensitive member, and a process cartridge and an electrophotographic apparatus each having the electrophotographic photosensitive member are provided. The surface layer of the electrophotographic photosensitive member includes a polymer having a specific repeating structural unit and fluorine-atom-containing resin particles. The fluorine-atom-containing particles in the surface layer are dispersed so as to be provided with particle sizes almost up to those of primary particles.
