Abstract

A release layer (2), which contains fluoropolymers is applied on a die surface (1a) of a shaping die (1), and is baked. An elastic layer (3) is applied onto the external surface of the release layer and is baked. A supporting layer (4) containing heat-resistant synthetic resin is applied onto the external surface of the elastic layer, and is dried. The dried supporting layer is polished to remove the unevenness, and the supporting layer is baked. The release layer, the elastic layer and the supporting layer are turned inside out to be removed from the die surface. The evenness of the fixing belt is improved, and the pressure unevenness is reduced.

Description

Technical field [0001] The present invention relates to a method for manufacturing a belt (such as a fixing belt, a transfer belt, etc.) for an image forming apparatus and related technologies. In addition, a fixing belt is used as a part of a fixing unit, which heats the toner image and fixes it to a recording medium in an image forming apparatus such as an electrophotographic copying machine, a facsimile machine, and a printer. The transfer belt is used as a part of the transfer unit to transfer the toner image formed on the image carrier to the recording medium. Background technique [0002] The fixing belt in the image forming apparatus will be described below. Traditionally, a heat fixing method, specifically a heat roller fixing method, has been commonly used as a fixing method. [0003] In the heat roller fixing method, a pair of rollers, including a heat roller and a rubber roller, are pressed and contacted. By passing the recording medium on which the toner image is form...
