PROBLEM TO BE SOLVED: To provide a heat roll fixing device where any problem generating in concern of fixing quality is eliminated by making the difference in the temperature in the axial direction of the heat roll in the heat roll fixing device small and where consumption of electricity is reduced when a small piece of printing paper is fixed. SOLUTION: In the device, a heating control means that is necessary according to the width size of the printing paper P is selected from a multiple number of heating control means and control to a specified temperature is carried out by the selected heating control means by turning on and off a halogen heater 33 with a control circuit 40 according to the surface periphery temperature of the heating roll that is measured by a temperature sensor 36. |
