Title:
A heating device and an image forming device
Document Type and Number:
Japanese Patent JP6137893
Kind Code:
B2
Abstract:
An image heating apparatus includes a rotatable heating member of magnetism-adjusted alloy configured to heat a toner image on a sheet; an excitation coil configured to generate a magnetic flux for electromagnetic induction heating of the rotatable heating member; a voltage source configured to supply an AC current to the excitation coil; a rotating mechanism configured to rotate the rotatable heating member at a first peripheral speed in an operation in a first image heating mode and configured to rotate the rotatable heating member at a second peripheral speed lower than the first peripheral speed in an operation in a second image heating mode; and a controller configured to control the voltage source in which a maximum current supplied to the excitation coil in the second image heating mode is smaller than a maximum current supplied to the excitation coil in the first image heating mode.
