Claims

[Scope of utility model registration request]

A heating device that has an electric heater and heats an article by passing current through the electric heater intermittently, comprising: a dummy heater having a thermal time constant that is substantially the same as that of the electric heater; a temperature detector that detects the temperature of the dummy heater; Impulse heater temperature control, comprising: switching means for energizing and de-energizing an electric heater and a dummy heater; and an arithmetic unit receiving the output of the temperature detector and determining the amount of current to be applied to the electric heater and the dummy heater next time.
