Abstract
A fixing unit includes a rotatable fixing member and a rotatable pressure applying member. The rotatable fixing member has a heat generating layer to generate heat when subject to a magnetic flux. The rotatable pressure applying member contacts the rotatable fixing member and applies pressure to the fixing member. The rotatable fixing member and the rotatable pressure applying member form a nip therebetween, to which a recording medium is passed through to fix an image on the recording medium. The rotatable fixing member includes a magnetism regulating layer deformable when subject to pressure from the rotatable pressure applying member.
