Fixing device of image forming apparatus |
摘要 |
A fixing device of an image forming apparatus of the present invention enables induction heating coils for a 100 V power source to set a ratio of inductance L to load resistance R of a heat roller to L/R <35x10<SUP>-6 </SUP>(H/Omega) and coil impedance Z (Omega) to Z<10 (Omega) and supplies a drive current at a high frequency of 40 to 70 kHz. By doing this, an eddy current generated in the heat roller is concentrated upon a metallic conductive layer by the skin effect and the heat generation efficiency of the heat roller is improved. |
