Abstract
The electromagnetic induction heating device has a simple construction, holds an object to be heated in a favorable heating condition while effectively suppressing the irregularities of heat generation of the object to be heated, and reduces an energy consumption. The electromagnetic induction heating device which heats the object to be heated provided with at least an electromagnetic induction heat generating layer includes a magnetic core made of magnetic material which is disposed in such a manner that it faces the electromagnetic induction heat generating layer of the object to be heated in an opposed manner, and an exciting coil which is wound around the magnetic core and generates a fluctuation magnetic field which penetrates the electromagnetic induction heat generating layer. A movable core which is capable of moving relative to the object to be heated so as to change the intensity of the fluctuation magnetic field which penetrates the electromagnetic induction heat generating layer is provided to at least a portion of the magnetic core. Furthermore, an image recording device is constructed such that the electromagnetic induction heating device is provided for an image carrying body which corresponds to the object to be heated and fixing unit or a pressure device is disposed at the downstream of the electromagnetic induction heating device.
