Abstract
A photoreceptor for electrophotography, a method for manufacturing the photoreceptor, and an electrophotographic device including the photoreceptor are disclosed. The photoreceptor for electrophotography includes a conductive substrate; and a photosensitive layer that is provided on the conductive substrate and that has an outermost surface layer containing at least a resin binder and an electron transport material. The resin binder is composed of a polyarylate resin having a structural unit represented by a Chemical Structural Formula 1, and the electron transport material is composed of a compound having a structure represented by a Structural Formula (ET2-3). The photoreceptor has high sensitivity, low residual electric potential, no light fatigue and sufficient stain resistance.
