Abstract
An image heating apparatus includes a rotation made of a metal, a heater to which a current is applied, whereby heat dissipates from the heater and the heater contacts an internal surface of the rotation member, and a pressure roller for pressurizing the rotation member together with the heater to form a nip, wherein the rotation member is electrically grounded via a fuse. By the virtue of the invention, it is rendered possible to suppress charging of the metal rotation member and to suppress a current leak to a main frame of an image forming apparatus.
