Electrophotographic photosensitive member, process cartridge, electrophotographic apparatus, and condensed polycyclic aromatic compound

An electrophotographic photosensitive member comprising:

• a conductive support formed of a material having electro-conductivity;
• and
• a photosensitive layer formed on the conductive support,
• a surface layer of the electrophotographic photosensitive member comprising a polymerized product of a hole transporting substance having a reactive functional group, wherein
• a structure other than the reactive functional group of the hole transporting substance is one of (i) a structure consisting of a carbon atom and a hydrogen atom, or (ii) a structure consisting of a carbon atom, a hydrogen atom and an oxygen atom,
• the structure other than the reactive functional group of the hole transporting substance comprises a structure which comprises a conjugate structure comprising 24 or more sp2 carbon atoms, wherein
• the conjugate structure comprises a condensed polycyclic structure comprising 12 or more sp2 carbon atoms, and
• the reactive functional group comprises one of an acryloyloxy group or a methacryloyloxy group, and wherein the hole transporting substance comprises two or more units of the condensed polycyclic structures.
