PROBLEM TO BE SOLVED: To provide a fixing device that can quickly increase the temperature of a fixing member. ! SOLUTION: In a fixing device including heating means, a fixing member that is heated by the heating means, an opposing member that forms a nip part with the fixing member, and temperature detection means for detecting the temperature of the fixing member, the heating means performs a first heating operation H1 of heating the fixing member upon the submission of a power determined on the basis of a temperature detected by the temperature detection means, and a second heating operation H2 of heating the fixing member upon the submission of a pre-set power, during one print job while switching the operations from each other, and can perform at least one of the switching from the first heating operation H1 to the second heating operation H2 and the switching from the second heating operation H2 to the first heating operation H1 at the timing different from a pre-set control cycle for defining the po |
