Since d 1 / D 1 <1, the following equation is obtained: T 1 <T (4), which is in comparison with the load torque of the device shown in FIG. 7 of the embodiment of the present invention shown in FIG. It can be seen that the load torque is reduced more.

2 and 13 are provided. The upper support roller 11 is made of a material that can withstand the urging force of the lower fixing roller 6, but the sliding members 12 and 13 do not need to have the same rigidity as the supporting roller 11, and have a friction coefficient with the upper fixing roller 1 as much as possible. Smaller materials can be selected. With this configuration, it is possible to prevent the load torque of the rotation of the upper fixing roller 1 from increasing. Further, since the contact area between the upper fixing roller 1, the supporting roller 11 and the sliding members 12 and 13 is small, it is possible to prevent the temperatures of both ends of the upper fixing roller from being significantly lowered. The support roller 11 and the sliding members 12 and 13 are engaged with the groove portion provided on the peripheral surface of the upper fixing roller 1, so that the upper fixing roller 1 is not displaced in the axial direction.
