This invention provides a photoreceptor for electrophotography, which has a low residual potential in an early stage, can suppress a rise in residual potential, can prevent a lowering in charged potential and undergoes no significant fatigue-derived deterioration even after repeated use. The photoreceptor for electrophotography is a highly durable photoreceptor for electrophotography, comprising a photosensitive layer comprising a cyclic phenol sulfide represented by general formula (1) and at least one charge transfer agent having an arylamino group in its molecule.
