PURPOSE:To prevent irregularity from being generated in a heat transfer treatment, by a method wherein a temperature change from the temperature before a heat transfer treatment to the temperature after the treatment is detected, and the fall of the temperature of a heating member due to the removal of heat by a material to be transferred is compensated by heating. CONSTITUTION:The temperature of the heating member 5 before the heat transfer treatment is detected by the first temperature sensor 7, and the temperature of the member 5 after the treatment is detected by the second temperature sensor 8. Signals from the sensors 7, 8 are fed into a temperature comparator, and a signal obtained by the comparator is fed to a sub-heater 10 provided at a stage upstream of a main heater 9 to control the heating temperature of the sub-heater 10, thereby compensating for the fall of the temperature of the heating member 5 due to the removal of heat through the heat transfer treatment. Accordingly, irregularities are prevented from being generated in the high-speed heat transfer treatment. |
