Abstract:
1. An electrophotographic photoreceptor comprising an organic photosensitive layer and a surface layer provided at a surface of the organic photosensitive layer, the surface layer including a first layer which is provided at a photosensitive layer side and has a refractive index of n1 and a second layer which is provided at an opposite side of the first layer to the organic photosensitive layer and has a refractive index of n2, and the photoreceptor satisfying the following Inequalities (1) to (3): where, in Inequalities (1) to (3), n0 represents the refractive index of the photosensitive layer, n1 represents the refractive index of the first layer, n2 represents the refractive index of the second layer, d1 represents the film thickness (nm) of the first layer, a represents an integer of 0 or more, and λ represents the wavelength (nm) of light with which the surface of the photoreceptor is irradiated when an electrostatic latent image is formed,
