Abstract
A conductive substrate for an electrophotographic photoreceptor includes a cylindrical conductive substrate, in which in a power spectrum obtained through fast Fourier transform of the roughness profile in the axial direction of the inner circumferential surface of the conductive substrate at both end portions in the axial direction, the sum S of intensity within the period range of 0.01 mm to 0.1 mm is 0.02 or greater and 0.10 or less.
