ABSTRACT:
An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on a support. The photosensitive layer is characterized by containing a specific triphenylamine compound having at least two phenyl groups each substituted with two alkyl groups including one alkyl group located in meta-position in conjunction with nitrogen atom or each substituted with three alkyl groups. The photosensitive member is suitable for providing an electrophotographic apparatus showing excellent electrophotographic characteristics such as a high photosensitivity, a good potential stability in repetitive use, a decreased transfer memory, no crack in the photosensitive layer and no crystallization of a charge-transporting material.
