Fixing device including plural demagnetizing coils and image forming apparatus
Abstract:
A fixing device includes a heat applying system having an exciting coil that creates a magnetic flux for generating induction heat in a heat generation layer provided in a fixing roller. Plural demagnetizing coils are stacked in plural layers partially overlying the exciting coil to cancel the magnetic flux at one end of the fixing roller. The plural demagnetizing coils partially overlap each other.
