Abstract

A method of producing a substrate for a photoreceptor having an exposing device therein for use in an electrophotographic apparatus, including the steps of: injecting polymerizable liquid material into a die whose inner surface is cylindrical; polymerizing the polymerizable liquid material while rotating and heating the die so that a substrate is formed inside the die; and removing the substrate from the die after the polymerizing, wherein the polymerizable liquid material is a transparent resin material and a thickness of the substrate is controlled according to an injecting amount of the polymerizable liquid material.
