PROBLEM TO BE SOLVED: To provide a fixing device capable of further improving a magnetic shielding effect, and an image forming device mounted with the same.SOLUTION: A fixing device includes: an induction heating coil (52); cores (54, 56, and 58) for forming a magnetic path around the coil; route switching means (60) for switching a route of a magnetic field toward a heating belt (48) to a first route promoting heating or a second route suppressing the heating; and a magnetic adjusting member (90) which is disposed over a switching area of a magnetic field route including both the routes, makes a magnetic flux from the core to the belt pass through in the first route, and shields the magnetic flux in the second route. The magnetic adjusting member includes a plurality of ring-shaped portions (90A, 90B, and 90C) in which the whole viewed from an axial direction of a line material thereof forms a serial endless shape, and which are divided and disposed according to plural sizes of carried sheets of paper. The core has a pair of parts extending along the first route, and at least one of the parts has a bending portion which is branched off from the first route and bent onto the second route. |
