METHOD OF MANUFACTURING A BELT MEMBER AND THE BELT MEMBER

摘要

A tube material is formed by continuously extruding a thermoplastic resin material in the shape of a cylinder that has a thickness of 100 μm and a circumferential length of 800 mm. After that, in a polishing process, the tube material is rubbed with a lapping tape of #2000 while being rotated in one direction at a fixed speed, so that circumferential stripes are formed on the outer circumferential surface of the tube material. Then, the circumferential stripes are thermally transferred by pressing the outer circumferential surface of the heated tube material against a mold surface that is finished in the shape of circumferential stripes by a thermal transfer process.

1. A method of manufacturing an endless belt member in a cylindrical shape made of a thermoplastic resin material to be abutted against a cleaning blade in an image forming apparatus, the method comprising:
a first process of forming an endless belt member in a cylindrical shape; a second process of mechanically polishing an outer surface of the endless belt member after the first process to form circumferentially extending stripes on an outer surface of the endless belt member, the stripes being formed with burrs; and a third process of heating the endless belt member after the second process, so that the burrs on the stripes are melted in a state that the stripes formed in the second process are maintained.
