Abstract
A fixing apparatus including a heat generating element having a first area, a second area, and a third area, the first area being located on an end portion side in an orthogonal direction orthogonal to a conveyance direction of a recording material and having a first heat generation amount per unit length in the orthogonal direction, the second area being located on an inner side than the first area in the orthogonal direction and having a second heat generation amount per unit length in the orthogonal direction, the third area being located on the inner side than the second area in the orthogonal direction and having a third heat generation amount per unit length in the orthogonal direction. The second heat generation amount is larger than the third heat generation amount, and the third heat generation amount is larger than the first heat generation amount.
