PURPOSE:To achieve effective heating, by providing detection switches detecting the end of a copying paper at upper and lower stream of a heating chamber and operating a blower only when the copy paper passes through a heating room. CONSTITUTION:Just when a copying paper 1 with a toner 2 is carried and the front en is detected at a detection switch 16 at the upper stream of a microwave heating chamber 15, a blower 11 is operadted and the wind pressure makes close or contacts the copying paper 1 to a ladder section 8. When the copying paper 1 heated and fixing moves from a ladder 8 and the rear end is detected at a detection switch 17 at lower stream to stop the operation of the blower 11. Since the blower 11 is operated only when the copied object passes through the heating chamber 15, heating with high efficiency can be achieved by avoiding the cooling of a microstrip line 4 due to wind by the blower 11. |
