Abstract
When a first timer, after started, counts a prescribed time interval, and becomes time-out, it is judged whether or not the total of a heat release value exceeds a first prescribed one, and if it does not exceed that value, then the first timer is restarted. If it exceeds, then a second timer is started, and a prescribed pause time is taken, before a heating element is driven, in a time interval when the second timer is counting. When the second timer becomes time-out, it is judged whether or not the total of the heat release value exceeds a second prescribed amount, and if it does exceed that value, the first timer is started. If it exceeds that value, then the second timer is restarted. In such a manner, in the operation of the second timer the prescribed pause time is taken before driving the heating element to make longer a driving period of the heating element than that during the operation of the first timer. Furthermore, the number of times of the operation of the second timer is controlled responsively to the heat release value.
