Abstract
A fixing film having an endless shape, comprising at least a base material, an elastic layer, and a release layer in this order, the release layer comprising a tube containing a fluorine resin, and a value of Xe to Xm is 1.20 or more, where when, in a chart of an X-ray diffraction peaks obtained by measuring the release layer with a reflection X-ray diffraction method, a maximum X-ray diffraction strength at 2θ=17 to 19° is defined as Ic, a maximum X-ray diffraction strength at 2θ=39.5 to 40.5° is defined as Ia, and a value of Ic/Ia is defined as X, Xe represents an average value of X in an edge region, and Xm represents an average value of X in a central region.
