Process for producing substrate for photosensitive drum and substrate for photosensitive drum

Abstract

The present invention relates to a process for producing a substrate for a photosensitive drum, comprising machining a cylindrical stock tube by a turning tool to form a cylindrical substrate having a surface roughness of 0.5 to 5 μm and being provided on the surface thereof with the streaks extending in the approximately circumferential direction thereof, said turning tool being constituted by monocrystalline diamond and having a cutting edge provided with a saw-like portion along an effective cutting length thereof, and a substrate which is suitable for the production of a photosensitive drum being free from the occurrence of interference fringes and has fine streaks uniformly formed on the surface thereof by machining without burrs, and the substrate capable of producing a higher-quality photosensitive drum. Such a substrate is suitable for the production of a photosensitive drum being free from the occurrence of interference fringes and has fine streaks uniformly formed on the surface thereof by machining without burrs.
