To provide a method that can efficiently inspect residual foreign matters on a cylindrical electrophotographic photoreceptor.SOLUTION: A method of forming an uneven shape on a surface of a cylindrical electrophotographic photoreceptor by making a mold member having an uneven shape contact with the surface of the cylindrical electrophotographic photoreceptor formed by providing a photosensitive layer on a cylindrical support and pressurizing the mold member onto the surface, and rotating the cylindrical electrophotographic photoreceptor in a direction perpendicular to the axial direction has an inspection process of inspecting residual foreign matters in or on the photosensitive layer before forming the uneven shape. The inspection process is performed by making a conductive member on which a high voltage is applied contact with the photosensitive layer and measuring a current flowing from the conductive member.SELECTED DRAWING: Figure 1 【課題】 円筒状電子写真感光体に残留する異物を効率よく検査ができる方法を提供する。【解決手段】 円筒状の支持体上に感光層を設けた円筒状電子写真感光体の表面に、凹凸形状を有する型部材を接触させて加圧し、前記円筒状電子写真感光体を軸方向と垂直な方向に回転させながら、前記円筒状電子写真感光体の表面に凹凸形状を形成する方法であって、凹凸形状を形成する前に、前記感光層の層中または表面に残留する異物を検査する検査工程を有し、前記検査工程は、高電圧を印加した導電性部材を、前記感光層に接触させて、前記導電性部材から流れる電流を測定することによって行うことを特徴とする。【選択図】 図１
