Photosensitive body

Abstract

Abstract PURPOSE:To obtain a photosensitive body having high sensitivity and maintaining superior stability and low residual potential even after repeated use by incorporating a specified hydrazone compound into a photosensitive layer together with photoconductive phthalocyanine powder. CONSTITUTION:The photosensitive body having high sensitivity and superior durability, undergoing little change in the surface potential, and accumulating hardly residual potential is obtd. by forming a single photosensitive layer contg. a hydrazone compound represented by the formula [where each of X and Y is H, lower alkyl, OCH3 or OC2H5, Z is lower alkyl, benzyl, lower alkoxy, phenoxy or benzyloxy, Z' is H, alkyl or alkoxy, R is lower alkyl, (substituted) aryl or benzyl, and the substituent is relatively lower alkoxy or the like] and photoconductive phthalocyanine particles dispersed in a binder. A laminate type photosensitive layer consisting of a charge generating layer contg. photoconductive phthalocyanine particles and a charge transferring layer contg. said hydrazone compound may be formed in place of said single photosensitive layer.
