。[Claims for Utility Model Registration] (1) A heat roller with a built-in heat source, a pressure roller that is in pressure contact with the heat roller and rotates together, and an adjacent non-contact temperature sensor that detects the temperature of the heat roller are provided. ,
The apparatus is equipped with a heat roller fixing device which is controlled by the temperature sensor and which temporarily stops the copying operation or reduces the number of copies per hour when the temperature drops to a certain set temperature due to continuous copying. In the image recording apparatus, a position moving means for the temperature sensor is provided so that the gap between the temperature sensor and the surface of the heat roller is different between before and after a predetermined period of time has elapsed since the main switch is turned on. An image recording device equipped with a heat roller fixing device. (2) The heat roller fixing device according to claim 1, wherein the temperature sensor is in contact with the surface of the heat roller while the heat roller is stationary after the main switch is turned on. Image recording device.
