ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, METHOD OF PRODUCING THE SAME, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC APPARATUS

摘要

An electrophotographic photosensitive member includes an undercoat layer containing a silane coupling agent having a divalent group represented by —NH— and an urethane resin. The modulus of elastic deformation (we/wt) of a surface of the undercoat layer satisfies formula (X), where the modulus of elastic deformation is measured by a universal hardness test.
