摘要： A fixing device forms a fixing nip by pressing a first roller, which is inside a rotation path of a rotating belt, with a second roller via the belt, and thermally fixes an unfixed image formed on a sheet S by passing the sheet S through the fixing nip while heating the belt by electromagnetic induction. The fixing device includes an excitation coil positioned outside said path, and a fixed plate that (i) is inside the path, substantially facing the excitation coil via the belt, (ii) contacts an inner surface of the belt, and (iii) keeps the belt on the path. A base member of the belt is a conductive heat generation layer containing no magnetic shunt alloy. The fixed plate includes a conductive layer and a magnetic shunt alloy layer that is closer to the belt than the conductive layer.
