Abstract

Provided is an electrophotographic photosensitive member excellent in suppression of image deletion and electric potential variation. The surface layer of the electrophotographic photosensitive member comprises a hole transporting substance. The hole transporting substance is one of a compound consisting of a carbon atom and a hydrogen atom, or a compound consisting of a carbon atom, a hydrogen atom, and an oxygen atom. The hole transporting substance comprises a conjugate structure containing 24 or more sp 2 carbon atoms. The conjugate structure comprises a condensed polycyclic structure comprising 12 or more sp 2 carbon atoms. A ratio of a number of sp 2 carbon atoms is 55% or more based on a total number of carbon atoms in the hole transporting substance, and a ratio of a number of sp 3 carbon atoms is 10% or more based on a total number of carbon atoms in the hole transporting substance.
