PURPOSE:To improve the sensitivity and repeatability of an electrophotographic sensitive body by forming a photosensitive layer contg. at least one kind of specified hydrazone compd. on an electroconductive base body. CONSTITUTION:At least one kind of hydrazone compd. expressed by formula I is contained in a photosensitive layer 20 formed on an electroconductive base body 1. In formula I, R1 is a (substituted)aryl group; R2 is H, halogen, alkyl group, aryl group, hydroxy group, or nitro group; Ar is a (substituted) condensed polycyclic aromatic hydrocarbon. By this constitution, an electrophotographic sensitive body having high sensitivity and high repeatability is obtd. |
