Photoconductor for electrophotography

A photoconductor for electrophotography comprising:

• a substrate;
• and
• a photosensitive layer formed on said substrate and including at least one tetrakisazo compound represented by one of the following general formulae (I), (II), (III) and (IV) as a charge generating substance:
• ##STR234## wherein, R stands for one of a hydrogen atom, an alkyl group and an aryl group which may have a substituent group, A stands for one of a coupler residuals represented by the following general formulae (V) to (XI) and n stands for an integer of 2 and 3;
• ##STR235## wherein, Z stands for a residual group which condenses with a benzen ring to form an aromatic polycyclic group or a heterocyclic group, X.sub.1 stands for an OR.sub.1 or an NR.sub.2 R.sub.3 (each of R.sub.1, R.sub.2 and R.sub.3 stands for one of a hydrogen atom, an alkyl group, an aryl group and a heterocyclic group, which groups may be or not may be substituted), each of X.sub.2 and X.sub.5 stands for an alkyl group, an aryl group and a heterocyclic group, which groups may de or not may be substituted, each om X.sub.3 and X.sub.6 stands for one of a hydrogen atom, a cyano group, a carbamoyl group, a carboxyl group, an ester group and an acyl group, each of X.sub.4 and X.sub.11 stands for one of a hydrogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aralkyl group, an aryl group and a heterocyclic group, which groups may be or not may be substituted, each of X.sub.7 and X.sub.8 stands for a hydrogen atom, a halogen atom, a nitro group, an alkyl group and an alkoxy group, last two of which groups may be or not may be substituted, X.sub.9 stands for one of an alkyl group, an aryl group, a carboxyl group, an ester group, which groups may me or not may be substituted, X.sub.10 stands for one of an aryl group and a heterocyclic group, moth of which may me or not may me substituted, and Y stands for a residual group which forms an aromatic ring or a heterocycle.
