Electrophotographic sensitive body

Abstract

Abstract PURPOSE:To enhance acceptance potential characteristics, sensitivity characteristics, image forming performance, to improve photosensitivity, and to reduce variation of said characteristics at the time of repeated uses by forming a photosensitive layer contg. a bisazo compd. CONSTITUTION:The bisazo compd. to be used as the material of the photosensitive layer of an electrophotographic sensitive body is represented by the formula shown on the right in which a side chain X is Br, and a side chain Y is ethyl. The superior carrier transfer performance of the bisazo compd. is utilized as the carrier transfer material of so-called laminated or dispersion type functionally separated electrophotographic sensitive body. For example, a carrier generating layer composed essentially of a carrier generating material, and a carrier transfer layer composed essentially of the carrier transfer material of the bisazo compd. may be laminated on a conductive substrate, or the carrier generating material may be dispersed into the carrier transfer layer to form the photosensitive layer.
