し画像定着を行なつている。(Technical Background of the Invention and Problems Thereof) Conventionally, as a heat fixing device for an ordinary electronic copying machine, a fixing roller formed by coating a cored bar with silicone rubber and grinding the surface flat is a side in contact with a black toner. The heat transfer roller has a structure in which a heat transfer roller with a coating layer of fluororesin on the opposite side is placed on the opposite side, and the toner is transferred onto the copy paper by the heat conducted from the heated heat transfer roller to the fixing roller. The image is fused and fused.

寿命が短縮されるという問題があつた。However, in the case of a heat fixing device for a full-color electronic copying machine, the color toner used for this has a lower melting point than black toner and is more likely to adhere to silicone rubber. The fixing roller whose surface was ground could not be used. That is, when the surface of the rubber roller is ground, the filler such as silica compounded in the rubber is exposed on the surface, and it is easy for the filler to adhere to the toner. Since the snare easily becomes a core of dirt, offset phenomenon of the copying machine and winding around the roller easily occur. In order to prevent such development from occurring, a releasing agent such as silicone oil has been conventionally applied to the surface of the fixing roller in the thermal fixing device. However, there is a problem in that the rubber coating layer of the roller is easily swelled by the release agent and the service life is shortened.

トな画像が得られるという利点がある。According to the heat fixing device of the embodiment configured in this way, as the heat transfer roller, a thin rubber roller having a large heat capacity is used as compared with a conventional surface coated with fluorine resin, so that the heating control temperature can be controlled. It can be lowered from 150-155 ° C to 145-150 ° C, which not only saves energy but also does not cause high temperature offset. Further, the heat transfer roller used in the examples has an advantage that not only the manufacturing is easy and the cost is low, but also the paper passing property is good and a soft image can be obtained.

Further, the rubber layer is less likely to swell with silicone oil, and the nip width can be increased to reduce the load between the rollers. Therefore, the service life of the fixing roller and the heat transfer roller is dramatically improved from the conventional 17,000 to 2000 copies to 40,000 to 50,000 copies.
