APPARATUS, METHOD AND SYSTEM FOR CONTROLLING BULGE RADIUS OF A PRESSURE MEMBER

摘要

An apparatus, system and method are provided for controlling a bulge radius of a pressure member in a belt-roll fuser. The belt-roll fuser has a first pressure member. The belt-roll fuser also has a fuser belt having a portion that faces a surface of the first pressure member at a region defining a fusing nip. The belt-roll fuser further has a second pressure member that faces another portion of the fuser belt at the fusing nip such that the fuser belt is entrained between the first pressure member and the second pressure member. The belt-roll fuser additionally has a deformation member configured to deform the first pressure member.
