PROBLEM TO BE SOLVED: To provide a substrate for a photoreceptor drum made of a synthetic resin which solves the problem of the decrease in surface smoothness, due to compounding of a reinforcing filler and which has preferable surface smoothness, while maintaining sufficient strength. SOLUTION: In the cylindrical substrate for a photosensitive drum, made of a conductive resin composition compounded with a reinforcing inorganic filler, a fibrous inorganic material, having 8 to 50μm fiber length and 0.1 to 5μm diameter, is used as the reinforcing inorganic filler. |
