め、その需要の拡大が期待されている。2. Description of the Related Art In recent years, as a method for fixing a toner image in an electronic copying machine, a laser beam printer, a laser facsimile, and the like, a film fixing method for heating and fixing an image on a recording material via a film has been developed. Attention has been paid to this because images can be obtained and the wait time can be reduced and power consumption can be reduced as compared with the conventional heat roller method and belt heating method. Among them, the method in which the pressure roller also functions as the drive roller as shown in FIG. 1 has advantages that the mechanism is simple and the apparatus can be downsized, and thus the demand is expected to increase.

The recording material 5 such as paper is introduced between the fixing film 3 and the pressure roller 4 in the press contact portion and is passed through the press contact portion together with the fixing film 3, so that the recording material 5 is heated via the fixing film 3. Thus, the unfixed toner image 6 formed on the recording material 5 is thermally fixed.

るなどの問題もあった。However, in the conventional pressure roller in which the core shaft 4a is covered with the silicone rubber layer 4b, the gripping force is strong, but there is a drawback that the releasability from toner and the like is poor. Further, in the roller provided with the fluororesin layer on the surface of the silicone rubber layer 4b, although the releasability for the toner and the like is good, the grip force is weak and there is a problem in conveying the recording material. In addition, when an FEP tube, for example, is used as the fluororesin tube, there is a problem that cracking occurs when the layer thickness is 50 μm or more due to poor flexibility.

Although attempts such as are being made, the former has a problem with durability, and
In the latter case, dust and the like adhered to the irregularities formed on the surface and became slippery, and the desired effect was not obtained.

上させることができる。Further, since the fluororesin tube and the fluororesin film of the present invention are composed of the fluororesin composition having at least the above-mentioned characteristics at least on the surface layer, they are useful as a product requiring such surface characteristics or a coating material thereof. Thus, for example, by using a fluororesin tube, it is possible to obtain a pressure roller suitable for a fixing device by a film fixing method, which is excellent in releasability and has good transportability to a recording material. The fixing property can be improved by using the film as the fixing film of the identification fixing device.
