Summary:PROBLEM TO BE SOLVED: To provide a fixing device which approximately fixes the temperature distribution of a heat roll by resolving the problem that a paper non-feed part falls into a high temperature state because of the paper size of paper fed to the heat roll. SOLUTION: An image forming device provided with the fixing device in an induction heating system which is provided with a cylindrical heat roll 1 made of a metallic conductor and a coil 11 which is arranged on the inside of the heat roll and is wound around an axis orthogonal to the axis of rotation of the heat roll, is provided an interlinking magnetic flux shielding means 21 which locally changes the distribution of interlinking magnetic fluxes of the heat roll generated from the coil.
