Claim:
1. A fixing device for fixing a toner image on a sheet-shaped recording medium, comprising: a rotational member configured to convey and heat the sheet-shaped recording medium, the rotational member including a common temperature sensor configured to sense a temperature of the first heating member and a temperature of the plurality of second heating members, the common temperature sensor being located at a position that overlaps with the one heat generation part of the first heating member in the direction orthogonal to the direction of conveyance of the sheet shaped recording medium; and a control part configured to control a ratio of a rate of lighting of the first heating member and a rate of lighting of the plurality of second heating members based on the temperature of the first heating member and the temperature of the plurality of second heating members in a case where the first heating member and the plurality of second heating members are lighted, wherein each of the auxiliary heat generation parts has a heating capacity less that of the one heat generation part and less than each of the plurality of heat generation parts of the plurality of second heating members, and wherein the auxiliary heat generation part is disposed between the heat generation parts in at least one of the plurality of second heating members.
