An electrophotographic photoreceptor includes a conductive support in which (i) a recessed portion having an opening diameter of greater than 400 μm and (ii) a recessed portion having an opening diameter of from 100 μm to 400 μm and a ratio of a depth to an opening diameter of greater than 0.12 are not present on an outer peripheral surface, wherein even in a case where a first recessed portion having an opening diameter of from 100 μm to 400 μm and a ratio of a depth to an opening diameter of 0.12 or less is present on the outer peripheral surface of the conductive support and a second recessed portion on which the first recessed portion is reflected is present on the outer peripheral surface of an outermost layer, a ratio of a depth to an opening diameter of the second recessed portion is not greater than 0.030.
