Photoconductor for electrophotography

A photoconductor for electrophotography, comprising:

• an electroconductive substrate;
• and
• a photosensitive layer formed on said substrate and including a charge generating substance comprised of at least one azo compound represented by general formulae (I) and (IV):
• ##STR131## wherein A in formulae (I) and (IV) is a coupler residual group represented by one of general formulae (VII) to (IX), ##STR132## each of R.sub.1 and R.sub.2 in formula (I) is selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group and an alkoxy group, each of which groups may be substituted, each of X.sub.2 and X.sub.5 is selected from the group consisting of an alkyl group and an aryl group, each of which groups may be substituted, each of X.sub.3 and X.sub.6 is selected from the group consisting of a hydrogen atom, a cyano group, a carbamoyl group, a carboxyl group, an ester group and an acyl group, each of which groups may be substituted, X.sub.4 is selected from the group consisting of a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aralkyl group, an aryl group and a heterocyclic group, each of which groups may be substituted, each of X.sub.7 and X.sub.8 is selected from the group consisting of a hydrogen atom, a halogen atom, a nitro group and the following groups which may be substituted, an alkyl group and an alkoxy group, X.sub.9 is selected from the group consisting of an alkyl group, an aryl group, a carboxyl group and an ester group, each of which groups may be substituted, and X.sub.10 is one of an aryl group and a heterocyclic group, each of which groups may be substituted.
