Zusammenfassung:A fixing device includes a fixing rotator to fix an unfixed image on a recording medium, a pressure member disposed opposite the fixing rotator to press an outer circumferential surface of the fixing rotator; a heating source disposed inside an inner circumferential surface of the fixing rotator to heat the fixing rotator, and a composite member disposed inside the inner circumferential surface. The composite member includes a first member, a second member attached to the first member, and an inspection region for measurement of glossiness. The first member and the second member have a difference in glossiness. The inspection region allows identification of which one of the first member and the second member is present on a surface of the inspection region based on the glossiness of the inspection region, and determination of that the fixing device has a desired fixing configuration based on a result of the identification.
