Abstract
A fixing device of the present invention has a fixing belt that is brought in contact with a recording medium to heat and fix a developer image formed on the recording medium. Plural supporting rollers support the fixing belt rotatably. Pressing rollers are provided opposing to the supporting rollers via the fixing belt for clamping and conveying the recording medium jointly with the fixing belt. A temperature controller raises the temperature of a heating roller to a second set temperature from a first set temperature after the temperature of the fixing belt drops to a prescribed temperature lower than that in the heating and fixing state, when shifting to the ready state after the heating and fixing state is complete.
