Photoconductor for electrophotography with a charge generating substance comprising a polycyclic and azo compound

A photoconductor for electrophotography having an improved sensitivity to visible light so as to improve reproduction of blue and red, comprising:

• an electroconductive substrate;
• and
• a photosensitive layer formed on said electroconductive substrate and including a charge generating substance consisting essentially off at least one polycyclic compound represented by general formula (I) and at least one azo compound represented by general formula (II):
• ##STR18## wherein X is selected from the group consisting of a hydrogen atom, a halogen atom and a cyano group, and n is an integer of 0 to 4;
• ##STR19## wherein R is selected from the group consisting of a hydrogen atom, a halogen atom and a substituted or unsubstituted alkyl group and alkoxy group, Z.sub.1 is selected from the group consisting of a substituted or unsubstituted alkyl group, aryl group and aromatic heterocyclic group, Z.sub.2 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 Z.sub.3 and Z.sub.4 is selected from the group consisting of a hydrogen atom, a halogen atom, a nitro group and a substituted or unsubstituted alkyl group and alkoxy group,
• whereby the photoconductor has an improved sensitivity to visible light so as to improve reproduction of blue and red.
