发明名称 Photosensitive member containing an azo dye
摘要 The present invention relates to a photosensitive member with a photosensitive layer on or over an electrically conductive substrate, in which the photosensitive layer comprises at least one of azo pigments selected from the group consisting of azo pigments represented by the following general formulas [I], [II] and [III]. <IMAGE> [I] <IMAGE> [II] <IMAGE> [III] in which Z1 is a residual group of a condensed ring excluding the benzene ring and the carbonyl group in the formula [I]; Z2 is a residual group of a condensed ring excluding the naphthalene ring and the carbonyl group in the formula [II]; Z1 and Z2 may have a substituent respectively; R1, R2, R3 and R4 represent independently a hydrogen atom, an alkyl group, an alkoxy group, a halogen atom, a hydroxy group or a nitro group; Ar1, Ar2, Ar3, Ar4 and Ar5 represent independently an arylene group which may have a substituent; Ar6 represents an aryl group which may have a substituent or a residual group of a coupler component having a phenolic hydroxy group; Cp1, Cp2 and Cp3 represent independently a residual group of a coupler component having a phenolic hydroxy group; n1 and n2 represent independently an integer of 0 or 1.
