Description of the Related Art Conventionally, a fixing device of this type of electrophotographic process has a pair of rollers consisting of a heat roller and a pressure roller, and a recording material such as a transfer paper on which an unfixed toner image is formed is provided in the pair of rollers. It is common that fixing is carried out by conveying under pressure between rollers. The heat roller is controlled within a predetermined temperature range so that its surface temperature is suitable for fixing. In order to control the temperature of the heat roller, a thermistor is often provided as a temperature detecting element in contact with the surface of the heat roller.

ということになる。The above-mentioned conventional fixing device has a drawback that the surface of the heat roller is damaged because the thermistor is pressed against the heat roller.
In addition, the toner adhered to the heat roller due to the offset development is collected and hardened on the surface of the thermistor, the adhesion between the thermistor and the heat roller is lowered, and the temperature detection accuracy is deteriorated. In order to solve these problems, a method has been adopted in which the thermistor is provided separately from the heat roller to prevent the heat roller from being scratched and also to prevent the thermistor from being soiled. However, in the configuration in which the thermistor is simply separated, the temperature of the thermistor has poor responsiveness to the temperature change of the heat roller and the control temperature accuracy is lowered.

Following closely, the temperature is kept slightly lower than that of the heat roller within a predetermined temperature difference. When the temperature detecting body detects a predetermined upper limit detection temperature, the heat generating portion of the temperature detecting body and the heat generating body of the heat roller simultaneously cut off the power supply. Thus, the temperature detector descends together with the heat roller while keeping a constant temperature difference between them due to heat dissipation in the discharge part. When the temperature detection body reaches the lower limit detection temperature, power is supplied again to the heat generation portion of the temperature detection body and the heat generation body of the heat roller to raise the temperature.
