A temperature control device adapted to increase the roll surface temperature to the fusing temperature after initiation of power supply. When the roll surface temperature is to be increased from a level below a reference temperature, the current is supplied until the roll surface temperature reaches a predetermined temperature lower than the fusing temperature, and when the roll surface temperature is to be increased from a level higher than the reference temperature, the current is supplied for a predetermined time which is set according to the roll surface temperature at the initiation of power supply.
