ABSTRACT:
A photoconductive composition is disclosed, containing at least one trisazo compound represented by the following general formula (1): ##STR1## wherein Z represents ##STR2## R.sup.6 represents a hydrogen atom, a lower alkyl group, an aryl group, an aryloxy group, an alkoxycarbonyl group, an aryloxycarbonyl group, an acyl group, or a substituted group of them; As', which may be the same or different, each represents ##STR3## B.sup.1, B.sup.2 and B.sup.3 each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or a substituted lower alkyl group or lower alkoxy group, and B.sup.1, B.sup.2 and B.sup.3 may be identical or different; X represents an atomic group necessary to form an aromatic ring or heterocyclic ring, which may be substituted or unsubstituted, by condensing with the benzene ring to which the hydroxyl group and Y are bonded; Y represents ##STR4## R.sup.1 represents an alkyl group, a phenyl group or a substituted alkyl or phenyl group; R.sup.2 represents a hydrogen atom, a lower alkyl group, a carbamoyl group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group or a substituted or unsubstituted amino group; R.sup.3 represents an alkyl group, an aromatic group or a heteroaromatic group or a substituted alkyl group, aromatic group or heteroaromatic group; and R.sup.4 and R.sup.5, which may be the same or different, each represents a hydrogen atom, an alkyl group, an aromatic group, a heteroaromatic group or a substituted alkyl group, aromatic group or heteroaromatic group, provided that R.sup.4 and R.sup.5 are not both hydrogen atoms, and R.sup.5 is not a hydrogen atom when Y is ##STR5## . An electrophotographic light-sensitive material is also disclosed, comprising an electrically conductive base and a layer containing an electric charge carrier transport compound and the trisazo compound as an electric charge carrier generating compound.
