Abstract
An electrophotographic photoreceptor includes a conductive substrate, an undercoat layer disposed on the conductive substrate, and a photosensitive layer disposed on the undercoat layer, in which an integrated value of an intensity in a period range of 0.01 mm or greater and 0.1 mm or less in a power spectrum obtained by performing fast Fourier transform on a roughness curve of an outer peripheral surface of the conductive substrate in an axial direction is 0.02 or greater and 0.10 or less, and the undercoat layer has a layer thickness of 10 μm or greater.
