Abstract

A method for producing a fixing device comprising: an endless belt having a base pipe made of metal; a nip member contacting an inner peripheral surface of the endless belt; and a roller having The shaft and the elastic portion covering the shaft; the annular band is crimped in the crimping region between the elastic portion and the crimping member. The method includes: covering each masking area at each end of the outer peripheral surface of the base pipe, the end being at the end of the roll in the axial direction; The impingement area at the outer peripheral surface of the tube, the impingement area is located between the covering areas, the covering and impacting are performed such that a boundary portion between the covering area and the impacting area is formed at a position outside the crimping area in the axial direction.

Description

technical field [0001] The present disclosure relates to a fixing device including an endless belt, and to a method for producing such a fixing device. Background technique [0002] A fixing device including a belt is well known in the technical field. Such a conventional fixing device includes an endless belt, a nip member provided in an inner space of the endless belt, and a pressure roller, which provides a nip region in cooperation with the nip member. The endless belt includes a base pipe made of metal and a coating formed over the outer surface of the base pipe and made of fluorine-containing resin. [0003] Japanese Patent Application Publication No. 2007-249186 discloses a fixing device having an endless belt in which the outer surface of the substrate tube is impacted in order to increase the adhesive strength between the substrate tube and the coating layer. Further, this publication also discloses an endless belt in which each end region of the substrate pipe in...
