  • Conductive support for electrophotographic photoreceptor, electrophotographic photoreceptor, and image forming apparatus
    Patent number: 9939745
    Abstract: A conductive support for an electrophotographic photoreceptor includes a metallic cylindrical member. The conductive support has a bare area exposed even after a photosensitive layer is disposed on the conductive support, and the outer circumferential surface of at least part of the bare area has a surface residual stress of about ?10 MPa or less.
    Type: Grant
