Abstract
An electrophotographic photoreceptor including a conductive substrate, a photosensitive layer, and a cross-linked resin surface layer comprising a cross-linked resin having a charge transport structure, which satisfies the following inequations:0.01<()<0.04  (1-1)0.01<()<0.04  (1-2)0.01<()<0.04  (1-3)0.01<()<0.04  (1-4)()>()  (2-1)()>()  (2-2)()>()  (2-3)()>()  (2-4)()>()  (2-5)()>()  (2-6)wherein WRa (μm) represents an arithmetic average roughness according to JIS-B0601:2001 of frequency components that are obtained by subjecting a one-dimensional data array of a surface profile of the electrophotographic photoreceptor to a wavelet transformation multiresolution analysis.
