Abstract:
1. An electrophotographic photoreceptor, comprising: a conductive substrate; a photosensitive layer located overlying the conductive substrate; and a cross-linked resin surface layer comprising a cross-linked resin having a charge transport structure, located overlying the photosensitive layer, wherein the following inequations are satisfied: wherein WRa (μm) represents an arithmetic average roughness according to JIS-B0601:2001of frequency components that are obtained by a method comprising: subjecting a one-dimensional data array of a surface profile of the electrophotographic photoreceptor, measured with a surface roughness and profile shape measuring instrument, to a wavelet transformation multiresolution analysis so as to be separated into six frequency components, HHH, HHL, HMH, HML, HLH, and HLL, each having a cycle length (μm) of 0 to 3, 1 to 6, 2 to 13, 4 to 25, 10 to 50, and 24 to 99, respectively; thinning a one-dimensional data array of the lowest frequency component HHL having a cycle length of from 24 to 99 (μm) so that the number of data arrays is reduced to from 1/10 to 1/100; and subjecting the thinned one-dimensional data array to the wavelet transformation multiresolution analysis so as to be separated into six frequency components, LHH, LHL, LMH, LML, LLH, and LLL, each having a cycle length (μm) of 26 to 106, 53 to 183, 106 to 318, 214 to 551, 431 to 954, and 867 to 1,654, respectively.
