H2 is provided on the side opposite to the side where the pressure roll 602 is pressurized. Conventionally, a conductive resistance layer was provided on the side pressed by the pressure roll 602, and glass coating was performed to ensure an insulating function. However, the thermal conductivity of ALN is better than that of glass, and the above-mentioned configuration is used. This is because heat can be efficiently transferred to the sheet material and fixed by taking it.

The temperature detection element 601e and the excessive temperature rise prevention element 601 are included in a.
f is a predetermined pressure, and is configured to contact the heater 601a. The temperature detection element 601e detects the temperature of the heater 601a, and a controller (not shown) controls the temperature of the heater 601a by the signal thereof. In addition, the excessive temperature rise prevention element 6
01f has a function of interrupting the supply of the alternating current to the heater 601a when the heater 601a reaches an abnormally high temperature.

例では下記の様な問題点がある。However, the above-mentioned conventional example has the following problems.

０１ａに対して位置がずれることになる。Since the conductive resistance layer H1 which generates heat when fixing a wide sheet material is located upstream of the width center of the heater 601a in the sheet passing direction of the sheet material, thermal expansion upstream and downstream of the heater 601a. The difference between the two causes a warp deformation as shown in FIG. When the above deformation occurs,
Since the temperature detection element and the excessive temperature rise prevention element are fixed to the stay holder (support) 601C, the heater 6
The position is deviated from 01a.

It causes the offset (hereinafter referred to as high temperature offset) and the curling of the sheet material. In addition, since the position of the excessive temperature rise prevention element 601f with respect to the heater 601a is also deviated, the supply of the alternating current cannot be interrupted at a predetermined temperature when an abnormality occurs, and in the worst case, the heater 601a is damaged.
