Electrophotographic sensitive body

Abstract

Abstract PURPOSE:To provide an electrophotographic sensitive body which has excellent carrier generatability, high sensitivity and high durability and is excellent in combination with a wide range of carrier transfer materials by providing a photosensitive layer contg. a specific bisazo pigment. CONSTITUTION:This photosensitive body has the bisazo compd. expressed by the formula I. In the formula, R1 and R2 denote a hydrogen atom., halogen atom., alkyl group, alkoxy group, nitro group, cyano group or hydroxy group. R1 and R2 may be the same or different. Z denotes an atom. group necessary for forming a carbon cyclic arom. ring or heterocyclic arom. ring and the examples of the heterocyclic arom. ring include a substd. or unsubstd. dibenzothiophene ring, carbazole ring, etc. These arom. rings may have a substituent. The substituent is exemplified by, for example, a halogen atom., amino group, alkyl group, hydroxy group, etc. (m) and (n) denote 1, 2 or 3 integer. The photosensitive body which is excellent in the sensitivity, the durability and the carrier generatability is thereby obtd.
