Patent ID: 8014711

Claim:
A fixing unit, comprising: a rotatable fixing member having a core metal made of aluminum or aluminum alloy, a heat insulating layer, a magnetism regulating layer, and a heat generating layer from an inner side to an outer side of the rotatable fixing member in such order, the heat generating layer generates heat when subject to a magnetic flux generated by a magnetic flux generator disposed outside of the rotatable fixing member; and a rotatable pressure applying member configured to contact the rotatable fixing member and to apply pressure to the fixing member, the rotatable fixing member and the rotatable pressure applying member forming a nip therebetween, through which a recording medium is passed through to fix an image on the recording medium, wherein the magnetism regulating layer is deformable when subject to pressure from the rotatable pressure applying member, and is made of a magnetic material having a Curie temperature of 100 to 300 degrees Celsius, and the heat insulating layer has a thickness of 10 mm or less.
