A fixing device, comprising: a fixing belt that is formed in an endless shape and has an induction heating layer; a fixing roller that is inserted inside the fixing belt, that is rotatably supported with a shaft extending in a predetermined direction as a rotation shaft, and that is configured to rotate with the fixing belt; a pressure roller that is pressed against the fixing belt and configured to rotate to thereby cause the fixing belt and the fixing roller to perform driven-rotation; a coil that is disposed at an interval from the fixing belt, at a side opposite from the pressure roller with respect to the fixing belt, that is wound in a loop shape elongated in the predetermined direction so as to extend over from one end portion to another end portion of the fixing belt in the predetermined direction, and that is configured to generate magnetic flux for induction heating by which the fixing belt is heated; and a belt regulating plate that is disposed at a side of an end surface of the fixing roller in the predetermined direction such that the belt regulating plate comes into contact with the fixing belt when the fixing belt moves in the predetermined direction to thereby regulate movement of the fixing belt in the predetermined direction, wherein the belt regulating plate has a multi-layer structure including a resin layer disposed on a side of the belt regulating plate close to the fixing belt and a nonmagnetic metal layer disposed on a side of the belt regulating plate away from the fixing belt, characterized in that a bent portion of the coil is partly disposed outside the belt regulating plate in the predetermined direction so that the regulating plate blocks magnetic flux generated at the bent portion and directed toward the inner peripheral surface of the fixing belt via the end surface of the fixing roller in the predetermined direction. a fixing belt that is formed in an endless shape and has an induction heating layer; a fixing roller that is inserted inside the fixing belt, that is rotatably supported with a shaft extending in a predetermined direction as a rotation shaft, and that is configured to rotate with the fixing belt; a pressure roller that is pressed against the fixing belt and configured to rotate to thereby cause the fixing belt and the fixing roller to perform driven-rotation; a coil that is disposed at an interval from the fixing belt, at a side opposite from the pressure roller with respect to the fixing belt, that is wound in a loop shape elongated in the predetermined direction so as to extend over from one end portion to another end portion of the fixing belt in the predetermined direction, and that is configured to generate magnetic flux for induction heating by which the fixing belt is heated; and a belt regulating plate that is disposed at a side of an end surface of the fixing roller in the predetermined direction such that the belt regulating plate comes into contact with the fixing belt when the fixing belt moves in the predetermined direction to thereby regulate movement of the fixing belt in the predetermined direction, wherein the belt regulating plate has a multi-layer structure including a resin layer disposed on a side of the belt regulating plate close to the fixing belt and a nonmagnetic metal layer disposed on a side of the belt regulating plate away from the fixing belt, characterized in that a bent portion of the coil is partly disposed outside the belt regulating plate in the predetermined direction so that the regulating plate blocks magnetic flux generated at the bent portion and directed toward the inner peripheral surface of the fixing belt via the end surface of the fixing roller in the predetermined direction.
