Abstract:
1. An electrophotographic photoreceptor, comprising an electroconductive substrate, an undercoat layer comprising a binder resin and a metal oxide particle having a refractive index in a range of from 2.0 to 3.0 formed on the electroconductive substrate, and a photosensitive layer formed on the undercoat layer, wherein when a dispersion liquid is prepared by dispersing the undercoat layer in a solvent mixture of methanol and 1-propanol in a weight ratio of 7:3, the dispersion liquid provides a difference of at most 0.3 (Abs) between an absorbance to light having a wavelength of 400 nm and an absorbance to light having a wavelength of 1,000 nm.
