Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings. pass figure 1 The overall configuration of the printer 1 as the image forming apparatus of the first embodiment will be described. figure 1 It is a diagram for explaining the arrangement of each component of the printer 1 according to the first embodiment of the present invention.

[0027] Such as figure 1 As shown, the printer 1 of the first embodiment includes an apparatus main body M. As shown in FIG. The apparatus main body M includes an image forming unit GK and a paper feeding and discharging unit KH. The image forming unit GK forms a toner image on a sheet-shaped sheet of paper T serving as a transfer target material based on the image information. The paper supply and discharge section KH supplies the paper T to the image forming section GK, and discharges the paper T on which the toner image is formed. The outer shape of the apparatus main body M is constitu...

Abstract

The invention provides a fixing device and an image forming device. The fixing device includes: a heating rotary body, a pressurizing rotary body, an induction coil, and a magnetic core having a detour core and a magnetic flux shielding member. The induction coil generates magnetic flux for heating the heating rotating body. The Curie temperature of the detour core is higher than the temperature of the detour core when the heating rotator becomes the fixing temperature for fixing the transfer material T and is higher than the temperature of the detour core when the heating rotator reaches its heat-resistant temperature. Low. The magnetic flux shielding member is disposed close to or in contact with the winding core and surrounded by the winding core. In addition, the image forming apparatus includes the fixing device. In the fixing device of the present invention, the temperature of the non-paper-passing portion of the heating rotor can be further suppressed from excessively rising.

Description

technical field [0001] The present invention relates to a fixing device and an image forming device including the fixing device. Background technique [0002] Conventionally, in an image forming apparatus, a belt-type fixing device capable of reducing heat capacity has attracted attention. In addition, in recent years, an electromagnetic induction heating (IH, induction heating) method that has the possibility of rapid heating and high-efficiency heating has attracted attention. [0003] In the fixing device of the electromagnetic induction heating method, there is a technique for suppressing an excessive rise in the temperature of an area (non-paper passing area, second area) outside the paper passing area (first area) through which the paper passes. The width of the paper (transferred material) (passing through) to the fixing device (the width of the paper in the direction perpendicular to the conveying direction of the paper: the passing paper width) is adjusted accordin...
