    摘要： An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on an electroconductive support. The photosensitive layer is characterized by containing a specific polycarbonate having a side chain comprising a charge-transporting group formed by nitrogen atom and benzene ring. The charge-transporting group may preferably has a specific triphenylamine structure, hydrazone structure or biphenyldiamine structure. The photosensitive layer is suitable for providing an electrophotographic apparatus showing excellent electrophotographic characteristics such as a high photosensitivity, a good potential stability in repetitive use.
