A method of making a fuser member having a support comprising the steps of:

Method of curing a fuser member overcoat at low temperatures

Fuser member overcoated with fluorocarbon-silicone random copolymer containing aluminum oxide

Release agent donor member having fluorocarbon thermoplastic random copolymer overcoat

Fuser member with fluorocarbon thermoplastics coating

Pressure member having fluorocarbon thermoplastic random copolymer overcoat

A fusing apparatus for heat fixing toner images onto a receiver medium. The apparatus includes a fuser member including an elastomeric contact surface; a pressure member forming a fusing nip to receive the receiver medium; a heater member including a conformable base cushion layer and an outer polymeric layer disposed over the base cushion layer, the heater member being in contact with the fuser and external thereto; and a radiant heat subsystem positioned externally of the heater member to provide heat to the surface of the first heater member which then contacts the fuser member so as to transfer heat thereto. The heater member is adapted to controllably exert pressure on the fuser member in order to controllably transfer heat to the fuser member, thereby providing control over the fusing capabilities of an eletrophotographic process.

External heater member and methods for fusing toner images

A fuser member whose outermost layer comprises a fluorocarbon-silicone interpenetrating network, comprising: (a) a first polymer comprising a fluorocarbon elastomer; (b) a second polymer selected from a curable polyfunctional poly(C alkyl)siloxane polymer; a curable polyfunctional poly(C alkyl)arylsiloxane polymer; and combinations thereof; and (c) a functionalized polydimethylsiloxane containing amine groups.

Fluorocarbon-silicone random copolymer for use in toner release layer

Disclosed is a release agent donor roller, and methods and fusing systems which incorporate the donor roller, for applying a polymeric release agent to a fuser roller in an electrophotographic apparatus. The donor roller comprises a base member with a polymeric outer layer thereover comprising a silicone material with a controlled, relatively high swelling characteristic in the release agent, i.e., the layer has a swell in 300 cts poly(dimethylsiloxane) oil maintained at a temperature of 175&deg; C. after 24 hours exposure of greater than 15% by weight. When operated in a fusing system, the donor roller exhibits relatively low toner contamination levels, even for relatively low melting polymer binder resins used in producing toners, such as polyester resins. The swell characteristic is still at an acceptable level such that the donor roller has adequate mechanical stability.

A photoreceptor cleaning brush for an electrostatographic imaging apparatus contains individual fibers provided with a finishing agent that is a water-miscible aliphatic organic compound containing a plurality of alcoholic hydroxy substituents. The finishing agent is selected from the group of compounds having a molecular weight of up to about 250 and polyethylene glycols having a number-average molecular weight of about 1000 to about 200,000. In an electrostatographic imaging apparatus, the photoconductive imaging element includes the described photoreceptor cleaning brush and a photoconductive surface portion that contains a polycarbonate binder resin. The cleaning brush removes toner from the photoconductive surface portion of the element without damaging it.

A fuser member having a support metallic core and a layer of material formed over the metallic core, the layer includes composite material, including a high molecular weight reactive polyfunctional poly(C alkyl)siloxane polymer; a cross-linked poly(dialkylsiloxane) incorporating an oxide, wherein the poly(dialkylsiloxane) has a weight average molecular weight before crosslinking of about 5,000 to 80,000; and a silane crosslinking agent.
