PURPOSE:To obtain the photosensitive body which has high sensitivity and excellent environmental resistance and is less degraded in electrostatic chargeability in spite of repetitive use by incorporating a compd. contg. both structural units of hindered amine and hindered phenol into the photosensitive body contg. a charge transfer material having >=5.45 ionization potential. CONSTITUTION:This electrophotographic sensitive body has the photosensitive layer contg. a charge generating material and the charge transfer material having >=5.45 ionization potential (Ip) on a conductive base body. The compd. having both structural units of the hindered amine structure and the hindered phenol structure is incorporated into such electrophotographic sensitive body. The photosensitive body which is improved in the sensitivity, has the excellent environmental resistance and is less degraded in the electrostatic chargeability in spite of the repetitive use is thereby obtd. |
