Patent ID: 7754403

Claim:
An electrophotoconductor, in which a photosensitive layer comprising a charge generating substance and a surface protective layer are layered on a conductive support in this order, and at least one of the photosensitive layer or the surface protective layer contains an asymmetric bishydroxy compound that can be represented by the general formula (1): wherein Ar 1 is an aryl or heterocyclic group which may have an arbitrary substituent group, Ar 2 and Ar 3 , different each other, are an arylene group or bivalent heterocyclic group which may have an arbitrary substituent group, Ar 4 is an arylene or bivalent heterocyclic group which may have an arbitrary substituent group, Ar 5 is hydrogen atom or an aryl, aralkyl or alkyl group which may have an arbitrary substituent group, R 1 and R 1 ′ are hydrogen atom or an alkyl group which may have an arbitrary substituent group, R 2 , R 2 ′, R 3 and R 3 ′ are hydrogen atom or an alkyl, aryl, heterocyclic or aralkyl group which may have an arbitrary substituent group, provided that R 1 and R 1 ′, R 2 and R 2 ′, and R 3 and R 3 ′ may be the same or different groups, respectively, and n is an integer from 0 to 2.
