Image heating apparatus

摘要

An image heating apparatus includes a rotatable heating member (10) configured to heat an image on a recording medium at a nip, driving means configured to drive the heating member, an endless belt (20) configured to form the nip with the heating member, and a driving roller (22) configured to drive the endless belt. In the image heating apparatus, the following expressions are satisfied: ¼ �¢ 1 < ¼ �¢ 2 0.005 < ¼ �¢ 1 < 0.3 V �¢ 1 < V �¢ 2
where µ1 is a friction coefficient between the endless belt and the driving roller, µ2 is a friction coefficient between the heating member and the endless belt, V1 is a peripheral speed of the heating member, and V2 is a peripheral speed of the driving roller.
