The apparatus may include a fuser having a run condition and an idle condition, the fuser having a fuser roller, a fuser roller heater, and a fuser temperature sensor which inputs to a logic and control system which controls the heating of the fuser roller heater. The fuser roller may be cooled during or after the idle condition, prior to the first receiving sheet entering the fuser. The fuser roller has end portions and a middle portion, and the middle portion may be cooled relative to said end portions. Additional aspects and representative embodiments are described herein.

Abstract: Disclosed is a fuser member, including fusing apparatus and electrostatographic methods which employ the fuser member, which has improved wear resistance and a reduced tendency to contaminate with toner particles. The fuser member comprises a core and a pliant coating thereon. The coating comprises a base cushion layer comprised of a first elastomeric composition, with a surface layer thereover comprised of a second elastomeric composition. The hardness of the surface layer is equal to or less than the hardness of the base cushion layer. In embodiments, the surface layer further comprises a particulate silica filler in an amount of about 10 volume percent or less, based on total volume of the surface layer.

Abstract: An electrostatographic member for use in electrostatographic processes is prepared by directly applying an elastomeric layer to a metal support (or core) that has been treated with corona discharge without primers or intermediate treatments. Adhesion of the elastomeric layer directly to the treated metal support is excellent. One or more such fuser members can be used in combination in an electrostatographic fuser system, such as the combination of a fuser roller and a pressure roller. Intermediate transfer members can also be prepared in this manner.
