Electrophotographic photoreceptor for negative electrification

A method of forming a negatively charged electrostatic latent image comprising

• a step of electrifying the surface of a photoreceptor in the negative electric potential, said photoreceptor comprising
• an elecroconductive substrate,
• a photo-sensitive layer containing a compound represented by general formula [A];
• ##STR479## wherein, R.sub.1 represents a hydrogen atom or a substituent;
• R.sub.2 represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group;
• Ar.sub.1 represents a hydrogen atom, a substituted or unsubstituted phenyl group, a substituted or unsubstituted naphthyl group;
• Ar.sub.2 represents a substituted or unsubstituted phenylene group or a substituted or unsubstituted phenylene group or a substituted or unsubstituted naphthylene group;
• Ar.sub.3 and Ar.sub.4 independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted phenyl group or a substituted or unsubstituted naphthyl group;
• and n represents an integer of 0 or 1;
• and a compound containing in its chemical structure a hindered phenolic structure unit.
