This device is shown in FIG. In FIG. 5, 1 is a fixing roller in which a non-adhesive material 3 is thinly coated on a metal roll 2 having good heat conductivity such as aluminum, and 4 is a core metal 5 coated with a relatively thick silicone rubber 6. It is a pressure contact roller. Both rollers 1 and 4 are pressed against each other with an appropriate force and rotate in the direction of the arrow.

The heat fixing roller 20 is formed by forming a thin metal layer 14 of nickel or the like on the outer periphery of the cylindrical body 11 by chemical plating, electroplating or the like, and further coating the non-adhesive layer 13 on the outer side thereof. In this case, if the outer peripheral surface of the cylindrical body 11 is roughened so that the inside of the thin metal layer 14 does not become a mirror surface, the infrared rays emitted from the lamp 9 are reflected inside the cylindrical heat fixing roller 20. The metal thin layer 14 is absorbed in the course of repeating. That is, the thin metal layer 14 can play the same role as the heat generating layer 12. Furthermore,
It is also possible to provide a heat generating layer 13 that absorbs infrared rays favorably between the cylindrical body 11 and the thin metal layer 14.

The temperature distribution model will be used for comparison with a conventional fixing roller. In a conventional fixing roller using a metal roller as a base, as shown in FIG. 4 (A), the inner surface of the metal roller absorbs infrared rays to generate heat, and this heat is transmitted from the inside of the metal roll to the outer surface of the non-adhesive layer surface. The temperature becomes the fixing roller temperature T 0 . Therefore, the inside of the fixing roller is necessarily higher than the fixing roller temperature T 0 . In this case, as a means for shortening the rising time, a material such as aluminum having a small heat capacity and a large heat conductivity is used for the metal roller, or a method of reducing the heat capacity by reducing the wall thickness has been used.

ることになる。In the heat fixing roller of the present invention, as shown in FIG. 4 (B), the infrared rays are absorbed by the heat generating layer provided on the outer surface of the cylindrical body, which is the base, without absorbing the infrared rays. The heat generated by is directly generated on the surface side of the heat fixing roller. On the one hand, this heat is transmitted through the non-adhesive layer and reaches the fixing roller temperature T 0 , and on the other hand, it also flows into the cylindrical body, which raises the temperature of this cylindrical body. In this case, the smaller the thermal conductivity of the cylindrical body, the better the flow of heat into the non-adhesive layer, and the shorter the rise of the fixing roller temperature T 0 .

時間の大幅な短縮が可能となる。In summary, in the conventional fixing roller, since the inside of the roller is heated, the temperature of the entire fixing roller needs to be higher than a desired temperature at the time of rising, whereas in the heat fixing roller of the present invention, the outer surface of the roller is directly heated. By doing so, only the outer surface needs to have a desired temperature, and the rise time can be greatly shortened.
