<p>PURPOSE:To remove adverse effect caused by a droplet on the surface of a guide by providing a heater for heating the upper and the lower parts of a guide which regulates a paper passing path, detecting the temperature at the parts and controlling a current supplied to the heater. CONSTITUTION:On the ejecting side of a fixing point formed between a heating roller 62 and a pressure roller 64, a guide part 76 for guiding paper passing through the fixing point to a paper ejecting roller is provided. The guide part 76 is constituted of an upper guide 76a, and a lower guide 76b, and heaters 80a and 80b are respectively provided on the guides 76a and 76b, furthermore, a heater controller is connected to each heater, and a temperature sensor detecting the surface temperature of the guide is attached thereto. As soon as the main switch of an image forming device is turned on, or in a state where the main switch is turned off, the heaters 80a and 80b are energized, and the guides 76a and 76b are warmed, and the heaters 80a and 80b are energized to keep the surface temperature of the guide constant based on the detected result by the temperature sensor.</p> |
