Disclosed is a photoreceptor comprising a support and a photosensitive layer which contains an azo compound of the formula (I):
wherein PI and P2 are independently a halogen atom, a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an acetylamido group, an alkylsulfonyl group,
(Q1 is an alkyl group, an alkoxy group, a phenyl group, an amino group, a hydroxy group or a hydrogen atom) or Q2-C- (Q1, Q3 and Q4
independently are a halogen atom, a hydrogen atom, an alkyl group, an alkoxy group, a phenyl group, an acyl group, an ester group, a hydroxy group or a vinyl group), the alkyl group, alkoxy group, aryl group, amino group and vinyl group may have a substituent;
Y1 and Y2 independently are a hydrogen atom, a halogen atom, a cyano group, a hydroxy group, an alkyl group or an- alkoxy group; m and n each represent an integer of 0 to 2, and m and n cannot be both 0; A represents a group representend by any one of the following formulae:
wherein Z is a group of atoms necessary for constituting a substituted or unsubstituted aromatic carbon ring or an aromatic heterocyclic ring, P3 is a substituted or unsubstituted carbamoyl group or a substituted or unsubstituted sulfamoyl group, R1 is a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted amino group, a substituted or unsubstituted carbamoyl group, a carboxyl group and its ester group or a cyano group, A' is a substituted or unsubstituted aryl group, R2 and R3 independently are a substituted or unsubstituted alkyl group, a substituted or unsubstituted aralkyl group or a substituted or unsubstituted aryl group.
