PRODUCTION METHOD FOR PHOTOSENSITIVE DRUM-USE SUBSTRATE AND PHOTOSENSITIVE DRUM-USE SUBSTRATE

摘要

A photosensitive drum-use substrate used in electrophotographic process is produced by ultrasonic-welding a resin-made flange or gear flange to an end of a cylindrical substrate formed from a conductive resin composition in which a conductive material and a filler is mixed/dispersed into a substrate resin. Ultrasonic welding can efficiently produce a photosensitive drum-use substrate, and positively provide a high-rotation-accuracy photosensitive drum-use substrate. Such a photosensitive drum-use substrate, when used, can form a high-quality image.
