ABSTRACT:
An electrophotograhic photoreceptor that has great ability to generate carriers and which has high sensitivity but low residual potential is disclosed. This photoreceptor is characterized by having formed on an electrically conductive support a light-sensitive layer containing a bisazo compound of the following formula: ##STR1## (wherein R.sub.1 is a cyano group, a chlorine atom or a bromine atom; X.sub.1 is a halogen atom, an alkyl group, an alkoxy group or a cyano group; X.sub.2 is a hydrogen atom, a halogen atom, an alkyl atom or an alkoxy group; A is ##STR2## wherein Y is a substituted or unsubstituted carbamoyl group or a substituted or unsubstituted sulfamoyl group; Z is an atomic group necessary for forming a substituted or unsubstituted aromatic hydrocarbon ring or a substituted or unsubstituted heteroaromatic ring; R.sub.2 is a hydrogen atom, a substituted or unsubstituted amino group, a substituted or unsubstituted carbamoyl group, a carboxy group or an ester group thereof; and A' is a substituted or unsubstituted aryl group).
