Problems solved by technology

On the contrary, due to the low magnetic permeability and deep skin depth of non-magnetic metals, the resistance value at the obtainable skin depth is too low to obtain high heat generation performance, but if the thickness tends to be smaller than the skin depth, the resistance The value increases accordingly, and the heat generation performance reaches the peak at the specified thickness

no. １ Embodiment approach ）

[0032]An image forming apparatus 1 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 3 . The image forming apparatus 1 includes: a paper feeding unit 2 disposed below it; a paper conveying unit 3 disposed on the side of the paper feeding unit 2; an image forming unit 4 disposed above the paper conveying unit 3; The fixing device 5 is on the discharge side of the paper; and the image reading part 6 is arranged above the image forming part 4 and the fixing device 5 .

[0033] The paper feeding unit 2 has a plurality of paper feeding cassettes 7 for storing paper P as a recording medium, and the paper P is fed one by one from the paper feeding cassette 7 selected from the plurality of paper feeding cassettes 7 by the rotation of the paper feeding roller 8 . sent out to the paper conveying section 3.

[0034] The paper P transported to the paper transport unit 3 is transported to the image forming unit 4 via the paper transpor...

no. ２ Embodiment approach ）

[0054] Next, a belt member 26 according to a second embodiment of the present invention will be described with reference to FIG. 4 .

[0055] In the second embodiment of the present invention, as shown in FIG. 4 , the belt member 26 includes: a resin base layer 26h; a first heat generating layer 26b laminated on the outer peripheral surface of the resin base layer 26h; The insulating layer 26i (insulating resin layer) on the surface; the second heat generating layer 26d formed on the outer peripheral surface of the insulating layer 26i; and the anti-oxidation film 26e, elastic layer 26f and release layer 26g.

[0056] The resin base layer 26h is made of insulating resin such as polyimide or polyamideimide, and is formed to have a thickness of about 50 to 100 μm. The insulating layer 26i is a layer for conducting and insulating between the first heat generating layer 26b and the second heat generating layer 26d, is made of insulating resin such as polyimide or polyamideimide, ...

Abstract

Provided is a belt member used in a fixing device of an electromagnetic induction heating system. The belt member includes an endless resin base layer, heat layers, and an insulating resin layer. The heat layers are two or more layers including a non-magnetic metal stacked on the resin base layer. The insulating resin layer is an insulating layer stacked between the heating layers.

Description

technical field [0001] The present invention relates to a belt member, a fixing device, and an image forming apparatus including these, and more particularly, to a belt member used in a fixing device of an electromagnetic induction heating method, a fixing device, and an image forming apparatus including these. Background technique [0002] The image forming apparatus transfers a toner image formed on an image carrier such as a photosensitive drum to a recording medium, and transports the recording medium carrying the toner image to a fixing device, and in the fixing device, heat and pressurize the toner image. The unfixed toner image on the recording medium is fixed to the recording medium. There is a fixing device of an electromagnetic induction heating method, which includes: a fixing roller; a belt member arranged on the outer peripheral surface of the fixing roller; a pressure roller pressed against the belt member; The induction heating unit fixes the toner image on t...
