Abstract
A control portion determines the lengths of time required to raise a plurality of heat generating elements to prescribed start-up completion target temperatures, and when a heat generating element determined to have the longest start-up requirement time among a plurality of heat generating elements is a second heat generating element, and a heat generating element determined to have shorter start-up requirement time than that of the second heat generating element among a plurality of heat generating elements is a first heat generating element, the control portion controls power to be supplied to the first heat generating element by changing a start-up control parameter for the first heat generating element with reference to the start-up performance of the second heat generating element.
