Summary:A fixing unit includes a first heat source configured to heat a roller, and a second heat source configured to heat the roller. The maximum value of a total amount of heat generated in the second heat source is smaller than that of the first heat source. The second heat source has an amount of heat generated higher in ends of the second heat source than in a center thereof in a distribution of the amount of heat generated in the axial direction. The second heat source has a rate of the amount of heat generated in the ends of the second heat source to that in the center thereof higher than a rate of the amount of heat generated in the ends of the first heat source to that in the center thereof.
