Abstract:
Provided are an electrophotographic photosensitive member capable of satisfying abrasion resistance and electrical properties and suppressing image deletion, and an electrophotographic apparatus and a process cartridge having the electrophotographic photosensitive member. A surface layer of the electrophotographic photosensitive member contains a polymer of a hole transport material having a polymerizable functional group, wherein the hole transport material has a specific structure.
