Abstract
A fixing unit () of an image forming apparatus () includes a heating member () having a first area where a sheet does not come into contact with the heating member () and a second area where the sheet comes into contact with the heating member (). The fixing unit () further includes a coil () forming a magnetic field, cores () forming a magnetic path near the coil (), a nonmagnetic magnetism adjusting member () arranged on the magnetic path and having a closed frame, and a switcher () capable of switching the magnetism adjusting member () between a first state where the magnetism adjusting member () generates an induction current resulting from the magnetic field to shield the magnetism in the first area, and a second state where the magnetism adjusting member () generates no induction current and the magnetism is not shielded in the first area.
