PURPOSE: To obtain the photosensitive layer which is high in sensitivity, small in change in bright part voltage and dark part voltage at continuous image forming by repeated charge and exposure, excellent in durability, moreover, very small in transferred memory even at reversal developing system, and prevents the crack of the photosensitive layer and crystalization of the charge transfer material by incorporating the triarylamine compd. having specified structure in a photosensitive layer.
CONSTITUTION: The body has the photosensitive layer containing the triarylamine compd. expressed by the formula. In the formula, R1, R2 and R3 is alkyl, alalkyl or arom. group which may have substd. group, Ar1, Ar2 and Ar3 is arom. group which may have substd. group. The electrophotographic sensitive body is composed by combination of the charge transfer material consisting of the triarylamine compd. expressed by time formula and a suitable charge generating material. A charge generating layer is applied after preparing the coating liq. by dispersing the charge generating material in a binding resin. The charge transfer layer is formed by combination of the triarylamine compd. and the binder resin.
