が提案された。Conventional configuration and its problems The heat fixing method of electrostatic plain paper copying machines is generally
A 7'7 run 1t heat source is used,
This method has the disadvantage that it takes a long time (warm-up time) to reach a predetermined temperature because the fixing roller is heated by heat conduction through side radiation and convection. As a method, a method was proposed in which high-frequency induction heating is applied to the fixing roller body and the resulting Joule heat is used as the heat source.

いため、ローワ本体ｌを均一加熱できなｈという問題を
有していた。The principle of high-frequency induction heating is that an induction coil is placed near the metal roller body, and by passing a high-frequency current through the coil μ, the magnetic field generated by the coil generates an electromotive force in the secondary winding of the transformer. Similarly, an electromotive force is induced in the roller body itself, an induced current flows, and the current causes the low = ?
The roller body is heated by generating Joule heat using an incorporeal resistor R. In this case, the positional relationship between the roller body and the induction coil depends on how the induction coil is wound around the outside of the roller body, and on which side of the cylindrical rope body 1 the induction coil A/2 is placed, as shown in FIG. A method of winding and arranging it in a spiral is considered, but in either case, the magnetic flux generated by the induction coil/L/2 cannot be uniformly supplied to the entire roller body 1, so the lower body 1 cannot be heated uniformly. There was a problem.
発明の目的
この発明の目的は、ローワ本体を均一加熱できる高周波

て、ローワ本体の均一加熱を図る。Structure of the Invention The high frequency induction heating roller of the present invention has an induction coil wound helically around the outer periphery of a nine cylindrical bobbin arranged concentrically within a conductive cylindrical lower body. Magnetic flux generated by energization is uniformly supplied to the entire roller body, thereby achieving uniform heating of the lower body.

That is, as shown in both figures, this high-frequency induction heating lobe has an insulating cylindrical bobbin 4 concentrically arranged inside a metal cylindrical rope main body 3, and an induction coil A15 is spirally arranged around the outer periphery of the bobbin 4. It is wrapped evenly.

の効果が大きい。In this way, since the induction coil 315 is evenly wound spirally around the pobbin 4 and arranged concentrically within the lower body 3, the magnetic flux generated by energizing the induction coil/L15 can be uniformly supplied to the entire loaf body 3. , the entire roller body 3 can be uniformly heated by causing an induced current to occur uniformly throughout the roller body 3. In particular, in the case of the fixing roller 2 for copying machines, it is strongly desired to equalize the roughness distribution of the roller body 3 in order to prevent the occurrence of fixing defects. The effect is great when used as a fixing loaf for copying machines.
