Patent ID: 7106999

Claim:
A fixing device for fixing a developer onto a recording medium, the device comprising: a heating member having a surface and rotatable about an axis, the axis extending in an axial direction; a magnetic-flux generating unit including: a coil disposed outside the heating member; and a current supplying unit supplying the coil with a current, thereby generating magnetic flux for heating the heating member through electromagnetic induction effect; and a pressing member in pressure contact with the heating member and pinching and conveying the recording medium in cooperation with the heating member in order to fix the developer on the recording medium, the pressing member including a first magnetic member that increases an amount of the magnetic flux that passes through the surface of the heating member, wherein the pressing member is formed with a hollow portion; wherein the first magnetic member is disposed inside the hollow portion, the first magnetic member being provided as a separate member from the pressing member, the first magnetic member not rotating with the pressing member; wherein the coil is disposed outside the pressing member, wherein a hollow space is defined inside the coil, and wherein the heating member is positioned in the hollow space of the coil; and wherein the coil is disposed at a position that is shifted, by a predetermined length, toward the first magnetic member from a position at which the axis of the heating member is positioned.
