Abstract
Provided are an electrophotographic photosensitive member which satisfies wear resistance and electrical characteristics, and in which image deletion is satisfactorily suppressed, and a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member. The electrophotographic photosensitive member comprises a surface layer which includes a polymerized product of a hole transporting substance having a reactive functional group, in which a structure other than the reactive functional group of the hole transporting substance is one of: a structure consisting of a carbon atom and a hydrogen atom; and a structure consisting of a carbon atom, a hydrogen atom and an oxygen atom, and the structure other than the reactive functional group of the hole transporting substance comprises a specific conjugate structure.
