Title: Fixing roller and production of fixing roller
Inventor: KATO KOICHI
IPC: F16C13/00
Filed: 1997-12-08
Abstract: PROBLEM TO BE SOLVED: To permit low temp. fixing and to obtain an image of high image quality which is stable with time without causing offset during fixing or entangling on a heating roller by using a powder coating material having a specified range of average particle size to form a polymer thin film on a metal roller. SOLUTION: A powder coating material having 1 to 3 μm average particle size is used to form a polymer thin film on a metal roller by powder coating to obtain a fixing roller. The powder coating material of a small particle size has 1 to 3 μm average particle size, which is very much smaller than a conventional material having about 20 μm particle size. Therefore, when a thin film is formed, a release layer having excellent surface smoothness can be formed without pinholes or cracks. By applying the release layer on an aluminum core metal roller, the film thickness can be made thin, which can increase the thermal efficiency. Therefore, offset development or entangling around the roller can be prevented, and characteristics of the roller can be kept for a long time.
