Abstract
In a warm-up period of a fixing apparatus of the present disclosure, a control unit supplies first electric power to a heater and thereafter supplies second electric power larger than the first electric power to the heater. The timing of starting to supply the second electric power is determined according to the degree of an increase in temperature sensed by a temperature sensing member after a driving signal is transmitted to a driving source.
