PURPOSE: To obtain high sensitivity, small potential fluctuation and excellent durability by incorporating a specific p-terphenyl compd. into a photosensitive layer. n CONSTITUTION: The p-terphenyl compd. expressed by the formula I is incorporated into the photosensitive layer. In the formula I, Ar 1 and Ar 2 denote a benzene ring which may have a substituent; R denotes a hydrogen atom, halogen atom, alkyl group or alkoxy group which may have a substituent. This p- terphenyl compd. exhibits the high sensitivity and durable potential stability. The electrophotographic sensitive body having the photosensitive layer contg. the p-terphenyl compd. has the high sensitivity in this way; in addition, the fluctuation in the bright part potential and the dark part potential is lessened at the time of forming the continuous images by repetitive electrifying and exposing and the durability is improved. n COPYRIGHT: (C)1990,JPO&Japio |
