SOLUTION: The electrophotographic photoreceptor includes an intermediate layer between an electroconductive support and a photosensitive layer. The intermediate layer contains a metal oxide fine particle the surface of which is treated with at least an anhydrous silicon dioxide, and a binder resin. The binder resin includes a polyamide resin obtained by subjecting at least a piperazine compound and an aliphatic di- or tri-carboxylic acid compound, a lower alkyl ester thereof or a mixture of the aliphatic di- or tri-carboxylic acid compound with the lower alkyl ester thereof to a condensation reaction.

摘要： PURPOSE:To obtain high sensitivity and high durability by providing a photosensitive layer having specific bistetracyano indenylidene compd. on a conductive base. CONSTITUTION:The photosensitive layer contg. the bistetracyano indenylidene compd. expressed by the formula (X is H, alkyl, alkoxy or acyl amino, Y is H, halogen or nitro, m is 1-4, n is 0, 1) is provided on the conductive base. Such azo compd. has two units of charge sepn. between the tetra cyano group and piperazine ring part within the same molecule and therefore said compd. contributes to a considerable improvement in the photosensitivity of the photosensitive layer when used in said layer. Since the compd. generates charge carriers at high efficiency when the compd. absorbs light, the compd. is suitable for the component of the charge generating layer of a lamination type photosensitive body. The photosensitive body which has high photosensitivity and good color sensitivity, decreases the fluctuation of the photosensitivity and electrostatic chargeability in repetitive use and has less photofatigue and excellent durability is thus obtd. The photosensitive body is used for a printer, etc. using a laser, LED, OFT, etc. as a light source in addition to a copying machine.

The obtained electrophotographic sensitive body is high in sensitivity, and has an advantage of small variation of the potentials in the light and in the dark during undergoing repeated cycles of charging and exposure.
