SUPPORT FOR ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC PHOTORECEPTOR, AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a support for an electrophotographic photoreceptor causing no unevenness in density and giving a good image and to provide an electrophotographic photoreceptor and an image forming apparatus. SOLUTION: When the surface roughness of the support for an electrophotographic photoreceptor is represented by a function y=f(x), an auto- correlation functionϕ(τ) of the above function represented by formula (1) (where 2T is observed time) does not have a peak at whichϕ(τ)>0.25ϕ(0) with the exception ofτ=0.
