Photoconductive receptor for an electrophotography

Claim 1

In a photoconductive receptor for use in electrophotography, said receptor being provided on a conductive support and having a photoconductive layer, said photoconductive layer comprising a carrier generating layer and a carrier transport layer, said carrier transport layer comprising an amine derivative represented by formula (A) and at least 1% by weight of a styryl compound represented by formula (B), based on the total weight of said amine derivative and said styryl compound; ##STR5## wherein, Ar 1 and Ar 2 each represent a phenyl group or a substituted phenyl group, said substituted phenyl group having at least one substituent selected from the group consisting of a halogen atom, an alkyl group, a nitro group and an alkoxy group; and Ar 3 is selected from the group consisting of a phenyl group, a naphthyl group, an anthryl group, a fluorenyl group, and a 5-7 membered heterocyclic ring, wherein said groups and said heterocyclic ring may be substituted with at least one substituent selected from the group consisting of a halogen atom, an alkyl group, a hydroxy group, an alkoxy group, an aryloxy group, a nitro group, a piperidino group, a morpholino group, a naphthyl group, an anthryl group and an amino group, said amino group may be substituted with at least one substituent selected from the group consisting of an acyl group, an alkyl group, an aryl group and an aralkyl group; ##STR6## wherein, R 1 and R 2 are each selected from the group consisting of an alkyl group, a substituted alkyl group, a phenyl group and a substituted phenyl group, wherein said substituted alkyl group and said substituted phenyl group have at least one substituent selected from the group consisting of an alkyl group, an alkoxy group and a phenyl group; R 3 is selected from the group consisting of a phenyl group, a naphthyl group, an anthryl group, a fluorenyl group and a carbazolyl group, wherein said R 3 groups may have at least one substituent selected from the group consisting of a halogen atom, a hydroxy group, an alkyl group, an alkoxy group and a phenyl group; and R 4 is selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a mono-alkyl amino group and a di-alkyl amino group.
