Fixing device using induction heating

摘要

A fixing device uses induction heating for causing alternating current to pass through an electromagnetic induction coil, whereby the fixing device is provided within an endless member such as a roller. The fixing device includes a core having a curved surface. The fixing device also includes the coil which is wound around a first axis on the surface of the core, so as to cover the surface of said core. The fixing device further includes a heat resistant bundling band that is wound on the coil around a second axis substantially perpendicular to the first axis, so as to fix the coil to the core.
