Patent ID: 8546049

Claim:
An electrophotographic photoconductor comprising a charge generation layer containing a charge generation material and a charge transfer layer containing a charge transfer material laminating in this order on a conductive support with an undercoat layer interposed between the charge generation layer and the conductive support, or comprising a monolayer type photosensitive layer containing a charge generation material and a charge transport material being formed on a conductive support with an undercoat layer interposed between the monolayer type photosensitive layer and the conductive support, wherein the charge transport layer or the monolayer type photosensitive layer contains, as a charge transfer material, a bisamine compound represented by the following general formula (I): wherein Ar 1 s each represent a phenyl or naphthyl group which may be substituted with one or more halogen atoms, or one or more straight or branched chain C 1 to C 4 alkyl or C 1 to C 4 alkoxy groups, Ar 2 s each are an arylene group selected from the group consisting of phenylene, naphthylene and biphenylene which may be substituted with one or more halogen atoms or one or more straight or branched chain C 1 to C 4 alkyl or C 1 to C 4 alkoxy groups; or each are a heteroarylene group selected from the group consisting of a furylene, thienylene and thiazolylene which may be substituted with one or more halogen atoms, or one or more straight or branched chain C 1 to C 4 alkyl or C 1 to C 4 alkoxy groups, Ar 3 s and Ar 4 s may be the same or different and each are a hydrogen atom, or a straight or branched chain C 1 to C 4 alkyl group which may be substituted with one or more substituents, whose substituent is halogen atom, or one or more straight or branched chain C 1 to C 4 alkyl groups or C 1 to C 4 alkoxy; or an aryl group selected from the group consisting of a phenyl, naphthyl and biphenyl group which may be substituted with one or more halogen atoms or one or more straight or branched chain C 1 to C 4 alkyl or C 1 to C 4 alkoxy groups, R 1 and R 2 are respectively an alkyl group selected from the group consisting of a methyl, ethyl, n-propyl, isopropyl, n-butyl and t-butyl group which may be substituted with halogen atom, and m is an integer of 0 or 1 and n is an integer of 1 to 4.
