PROBLEM TO BE SOLVED: To provide a photoreceptor drum substrate for an electrophotographic device used for a photoreceptor drum that stably gives a defect-free electrophotographic image, is light-weight and withstands long-term use. SOLUTION: The photoreceptor drum substrate 1 is used for the photoreceptor drum that is disposed in am electrophotographic device and bends very slightly and elastically, in combination with at least on heard member such as a hard roll or blade. The substrate comprises an aluminum cylindrical body. The modulus of flexural elasticity of the substrate 1 to load F on the cylindrical part in the radial direction is 0.00015-0.05000 N(mm.mm), and the tensile strength of the cylindrical part is 150 N/mm2 or larger. The substrate 1 is preferably manufacturing from an ironed material 107 having a folded part 107b with a circuit space 107c. |
