Abstract
A fixing apparatus comprises a rotating body that conveys a sheet in a first direction, first and second heating sections, and first and second temperature detectors. In the first heating section, a calorific value per unit length in a second direction orthogonal to the first direction, at the center of the first heating section is larger than that at both ends thereof. In the second heating section, a calorific value per unit length in the second direction, at both ends of the second heating section is larger than that at the center thereof. The first temperature detector is configured to detect a temperature of a central part of a heating area of the rotating body heated by one of the first and second heating sections. The second temperature detector is configured to detect a temperature outside of the heating area of the rotating body.
