Abstract
A fuser includes a pressure pad forming a nip with a fuser belt between the pad and a fuser rotator. A pressure face in contact with the belt has profiles in planes normal to the axis of the rotator. The profiles each include a reference section, the first to come into contact with the rotator with the belt in between when the pad forms the nip, and a boundary section at a threshold distance from the reference section in the width direction of the nip. When the pad is apart from the nip due to removal of a force applied by a pusher unit, the boundary section is, relative to the reference section, more largely displaced in the opposite direction to that of the rotator in one of the profiles located at a larger distance from a center portion of the pad in the axial direction of the rotator.
