PURPOSE:To obtain an electrophotographic sensitive body which has less photofatigue and has excellent durability by using a specific N-aminoindoline deriv. as an electric charge transfer material. CONSTITUTION:The N-amino-2,3,3-trimethylindoline deriv. which is expressed by formula (I) has excellent solubility with a high-polymer binder and excellent electrophotographic characteristics is used as the charge transfer material. The photosensitive body contg. the indoline deriv. (I) has a photosensitive layer 5 consisting of an electric charge generating layer 3 essentially consisting of a charge generating material 2 and the charge transfer layer 4 uniformly contg. the indoline deriv. (I) on a conductive base 1. The indoline deriv. (I) is used as the charge transfer material and forms the charge transfer layer 4 together with the binder. The electrophotographic sensitive body which has high sensitivity, is small in residual potential, has the less photofatigue even after repetitive use and has the excellent durability is thereby obtd. |
