Patent ID: 7392005

Claim:
A fixing apparatus comprising: a heat rotation member and an endless belt configured to heat-fix an unfixed toner image on a recording medium at a nip therebetween, the heat rotation member being disposed so as to be in contact with the unfixed toner image at the nip; a driving device configured to drive the heat rotation member to rotate; and a driving roller configured to drive the endless belt to rotate and to press the endless belt toward the heat rotation member, wherein the following expressions are satisfied: μ2<μ1, 0.14<μ1, 0.005<μ2<0.3, and 1<V2/V1<1.2, where μ 1 is a friction coefficient between the heat rotation member and the endless belt, μ 2 is a friction coefficient between the endless belt and the driving roller, V 1 is a peripheral speed of the heat rotation member, and V 2 is a peripheral speed of the driving roller.
