ABSTRACT:
The invention provides an electrophotographic photoreceptor excellent in various characteristics, especially effectively protected from light fatigue and stable against repeated use. The photoreceptor comprises an electroconductive substrate having placed thereon a photosensitive layer which contains a bisazo compound of the formula [I]: ##STR1## a diamine derivative of the formula [IV]: ##STR2## and a specific amount of a phenolic antioxidant, and the photoreceptor contains, if necessary, an intermediate layer between the electroconductive substrate and the photosensitive layer.
