Abstract
In an image forming apparatus, a fixing condition such as a target control temperature of a heater is changed depending on whether a first resistance heating element and a second resistance heating element of the heater are connected in series or in parallel such that a similar fixing performance is achieved regardless of whether the first resistance heating element and the second resistance heating element are connected in series or in parallel.
