Electrophotographic photoreceptor, electrophotographic devoce, PROCESS CARTRIDGE, and fused polycyclic aromatic compounds

The present invention relates to an electrophotographic photoreceptor, an electrophotographic devoce, a process cartridge, and fused polycyclic aromatic compounds. A surface layer of the electrophotographic photoreceptor comprises a polymer obtained by polymerization of a hole transporting compound having a first reactive functional group and a compound having a second reactive functional group capable of reacting with the first reactive functional group. The structure of the hole transporting compound other than the first reactive functional group only has carbon atoms or hydrogen atoms, or has only carbon atoms, hydrogen atoms, and oxygen atoms.
