PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor which reduces image defects in image output as compared with before. SOLUTION: When the outer peripheral surface and the inner peripheral surface of a cylindrical substrate for an electrophotographic photoreceptor are rinsed by spraying a rinsing liquid on the surfaces, timing to start spraying the rinsing liquid from the outer periphery side and the inner periphery side is controlled, and the rinsing liquid is sprayed from the outer periphery side to wash away a detergent on the upper end face of the cylindrical substrate to the inner periphery side of the cylindrical substrate. The detergent and foreign matter remaining on the upper end face of the cylindrical substrate can be prevented from dropping on the outer peripheral surface of the cylindrical substrate, and stain and foreign matter deposited on the outer peripheral surface of the cylindrical substrate can be reduced.
