。That is, the fixing device shown in FIG. 6 includes an image forming means that forms an unfixed toner image by carrying toner made of heat-melting resin or the like on a transfer material, and an image forming means that is driven while being in opposing pressure contact with the heating member 4. a pressure roller 5 that brings the transfer material into close contact with the heating body 4 via a fixing film 3 that moves at the same speed as the conveyance speed of the transfer material, and presses the unfixed toner image on the transfer material. In this case, when the fixing film 3 is moved in the transport direction,
If the amount of sagging is too small, it may lead to defective fixing or damage to the fixing film 3. To eliminate this misalignment of the fixing film 3,
The dimensional accuracy of the fixing film 3, the parallelism of at least two rollers 1.2 for conveying the fixing film 3, the accuracy of the center distance, etc. are excellent.

がｔよい。However, there is a limit W to the assembly viscosity, and displacement of the fixing film 3 will definitely occur. Therefore, control is performed to detect the waviness of the fixing film 3 and correct it. The shift of the fixing film 3 is detected using a detection sensor 6 such as a photointerrupter, which detects when the fixing film 3 shifts by 1 degree (in the case of Fig. 6, the direction of force perpendicular to the paper surface) reaches a certain amount. It is. That is, when a certain amount of sagging occurs in the fixing film 3, one end of the shaft of the driven roller 1 is turned up and down, the fixing film 3 is twisted, and the fixed film 3 is shifted in the opposite direction to the direction of shift before control. The fixing film 3 is of a type in which the fixing film 3 is moved back to its original direction, and the fixing film 3 always repeats reciprocating motion in the direction perpendicular to the conveyance. It is good to stop exercising.
