Problems solved by technology

Therefore, if the method is adopted in which the fluororesin layer is baked on the outer surface of the elastic layer formed of silicone rubber having a heat-resistant temperature of about 250°C, the silicone rubber is hardened by heat and loses its elasticity.

Embodiment approach 1

[0034] figure 1 is a cross-sectional view of an annulus according to the invention, figure 2 Yes figure 1 A sectional view of the main part at the A-A plane in . The endless belt 1 according to the present invention includes: a release layer 2 as the outermost layer, which is formed of fluororesin, and whose outer surface is constituted by a molding surface; a first adhesive layer 3, which is arranged following the release layer 2 ; an elastic layer 4, which follows the first adhesive layer 3; a second adhesive layer consisting of two layers 5a and 5b, which follows the elastic layer 4; and a support layer 6 as the innermost layer, which Follow layer 5b settings. In other words, the endless belt according to the present invention is an endless belt having the following layers: a release layer 2 as the outermost layer of the endless belt 1, which is formed of fluororesin and has an outer surface composed of a molding surface; a support layer 6; and an elastic layer 4 as an...

Embodiment approach 2

[0056] image 3 is a sectional view for explaining a method of manufacturing an endless belt according to the present invention, Figure 4 Yes image 3 A cross-sectional view of the main part at the B-B plane. The manufacturing method of the endless belt according to the present invention comprises: a release layer 2 made of fluororesin is coated on the outer peripheral surface of the ring forming mold 7; a first bonding layer 3 is coated on the release layer 2; Afterwards, these layers are baked at a given temperature; Afterwards, an elastic layer 4 is coated on the first bonding layer 3 and is baked at a given temperature; Afterwards, a bonded by two A second adhesive layer composed of layers 5a and 5b is applied on the elastic layer 4 and dried; after that, a support layer 6 is applied on the layer 5b in the second adhesive layer and heated at a given temperature to be baked. Next, if Figure 5 As shown, the endless belt 1 is separated from the forming mold 7 by being ...

Embodiment approach 3

[0065] A method for manufacturing an endless belt according to the present invention includes: a release layer made of fluororesin is coated on the outer peripheral surface of the ring forming mold and baked at a given temperature; after that, the release layer The surface is etched; after that, an elastic layer is coated on the etched surface of the release layer and baked at a given temperature; after that, an adhesive layer is coated on the elastic layer and dried; after that , a support layer is coated on the bonding layer and baked at a given temperature. Next, in the same manner as in Embodiment Mode 2, the endless belt is separated from the molding die by being turned inside out and pulled down. In this way, an endless belt according to the present invention is completed, comprising: a release layer as the outermost layer of the endless belt, which is formed of fluororesin and has an outer surface composed of a molding surface; layer; and an elastic layer as an interme...

Abstract

An annular endless belt (1), comprising a release layer (2) formed of fluororesin and having an outer surface formed of a molded surface disposed as an outermost layer, a support layer (6) disposed as an innermost layer, and an elastic layer (4) disposed between the outermost layer and the innermost layer, whereby the fluororesin layer as the release layer can be formed by coating on the outer surface of the endless belt without hardening the elastic layer thereof used as the fixing belt of a color copying machine.

Description

technical field [0001] The present invention relates to an endless belt which can be used as, for example, a full-color image fixing belt which is used in electrophotographic copiers, facsimile machines, printers, etc. In a fixing unit for fixing a toner image on printing paper or the like; in addition, the present invention also relates to a method of manufacturing such an endless belt. Background technique [0002] In an image forming apparatus such as an electrophotographic copier, facsimile, printer, etc., at the final stage of printing or copying, a toner image on a transfer material such as transfer paper is heated and fused to be fixed on the transfer paper. [0003] A common method of accomplishing such fixing is heat fixing. Heretofore, the heat roller fixing method has been widely used. According to this heat roller fixing method, a pair of rollers consisting of a rubber roller and a heating roller provided with a heater inside and coated on the outer periphery w...
