Abstract
PURPOSE: To stabilize operation over a long period of time by specifying the constitution and temperature-detecting method of pressure- and fixing rollers.
CONSTITUTION: A covering layer 3 of good release characteristic is provided on the surface of a metallic pipe 2 and a halogen heater 4 is disposed in the inside to form a fixing roller 1. A temperature detecting element 12 of thermistors or the like is disposed on the peripheral surface of the support member entry side of said roller. An elastic deformation layer 7 and a covering layer 8 of good release characteristic are subsequently provided on the surface of a metallic pipe 6 and a halogen heater 9 is disposed in the inside to form a pressure roller 5. A temperature detecting element 13 is disposed on the side end near the peripheral surface thereof making contact with the fixing roller 1, in such a manner as to make contact with the exposed surface of the metallic pipe 6. With this arrangement, the temperature of the halogen heater is well controlled by the temperature detecting element 12 and since the temperature detecting element 13 detects temperature on the surface of the metallic pipe 6, the halogen heater 9 may be controlled so as to be operated during the time when the heat flow from the halogen heater 9 flows to the peripheral surface of the pressure roller 5 even if the temperature of the surface of the pressure roller 5 rises along with the rise in the temperature of the surface of the fixing roller 1.
