| 摘要 |
The present invention relates to a method and device each for controlling the temperature of a thermal fixing machine where a toner image is fixed on a recording medium in a printer, a facsimile apparatus, or a copying machine using electrophotograpic technique. The object is to control the temperature, of a thermal fixing machine with high accuracy by increasing substantially a resolution of an A/D converter without increasing a device manufacturing cost, and reducing an effect on a temperature detection value due to noises. The system includes temperature detecting device for detecting the temperature of a thermal fixing machine as a digital value, sampling device for sampling plural temperature detection values detected with said temperature detecting device, and control device for subjecting a heater to an on/off control based on plural temperature detection values sampled by the sampling device.
