PURPOSE:To obtain a photosensitive body high in sensitivity, small in residual potential, and high in electrostatic charge transfer efficiency, accordingly, raisable in copying speed by incorporating a specified hydrazone compd. in a photoconductive layer. CONSTITUTION:The electrophotographic sensitive body has the photosensitive layer contg. at least one of compds. as a charge transfer material, preferably, in an amt. of 10-300pts.wt. per 100pts.wt. of a binder resin, represented by the formula shown on the right in which R1, R2 are each H, halogen, optionally substd. alkyl or such alkoxy; R3 is alkyl or alkoxy each optionally substd. by amino, alkoxy, or halogen; R4 is optionally substd. alkyl or alkoxy; R5, R6 are each optionally substd. alkyl, such aralkyl, or such aryl. As a result, the obtained photosensitive body is high in sensitivity, and charge retentivity, and superior in stability of sensitivity against change of environmental conditions, and durability. |
