An apparatus for enabling the uniform application of a layer of a coating composition to a tubular substrate includes a shaft, and upper and lower circular rim members of equal diameter that are concentrically attached to the shaft. A pneumatically inflatable tube disposed on each circular rim member has an outer diameter that is variable with changes in its internal pressure. A first flexible cylindrical sheet in contact with the inflatable tubes has parallel edges that form a first slit sufficiently wide to permit movement of the first sheet in response to pressure variation in the tubes. A second flexible cylindrical sheet surrounding the first cylindrical sheet has parallel edges that form a second slit sufficiently wide to permit movement of the second sheet also in response to pressure variation. The second slit is laterally displaced from the first slit, and the second cylindrical sheet has a diameter nearly equal to the specified diameter of the substrate. Each of the tubes is inflatable to a pressure sufficient to provide the substrate with a smooth cylindrical outer surface for uniform application of a coating.

Pneumatically adjustable apparatus for coating toner fusing belt substrate and method for using same

The present invention is a fuser member that includes a core member having a rigid outer surface. A resilient layer made of an elastomer is disposed on outer surface. A primer layer of perfluoroalkoxy resin and trifluoroethylene-perfluoroethylvinyl ether-perfluoroethylene vinyl phosphate or a mixture of perfluoroalkoxy resin and trifluoroethylene-perfluoroethylvinyl bonds the resilient layer and an outer layer. The outer layer comprises fluoropolymer resin selected from the group consisting of polytetrafluoroethylene, polyperfluoroalkoxy-tetrafluoroethylene, polyfluorinated ethylene-propylene, and blends thereof.

Fuser member

This invention relates to a low camping fluorocarbon thermoplastic random copolymer roller coating having a closely controlled curing agent content.

Low damping fuser roller composition

This invention relates to an improved fuser roller for use in a high speed fusing station where improved heat transfer from the fuser roller to the fused substrates is required. The invention also relates to an improved fuser system using the improved fuser roller of the present invention in combination with an improved pressure roller to produce an improved fuser section.

Fuser roller and fusing station

Disclosed are fuser members, apparatus and methods which employ compositions that can be varied to provide a fused toner image with a selected gloss level. In embodiments, the apparatus and methods employ a fusing member having an outer contact surface thereon which contacts a previously fused toner image under conditions of elevated temperature and pressure. The contact surface has a Gardner G60 gloss of up to about 35 and is comprised of a fluorocarbon thermoplastic random copolymer co-cured with a fluorinated resin, such as polyfluoroethylenepropylene (FEP). In embodiments, the contact surface comprises a fluorocarbon thermoplastic random copolymer co-cured with a fluorinated resin including subunits of:&#x2014;(CH2 CF2)-, &#x2014;(CF2CF(CF3))-, and &#x2014;(CF2 CF2)-,wherein:

Method of curing a fuser member overcoat at low temperatures

A controlled modulus fusing-station member inclusive of a durable, tough, elastically deformable layer incorporating hollow flexible filler particles. The elastically deformable layer is preferably a single layer on a substrate, the substrate preferably a core member of a fuser roller or a pressure roller. The elastically deformable layer is made from a dry formulation inclusive of: a fluoro-thermoplastic polymer powder; microspheres in the form of unexpanded microspheres or expanded microballoons; and solid filler particles including strength-enhancing filler particles and thermal-conductivity-enhancing filler particles. The dry formulation can be thermally cured or electron-beam cured. Preferably, the dry formulation is thermally cured and further includes a curing catalyst, preferably a peroxide catalyst. Alternatively, the curing catalyst can be a bisphenol residue.

Fuser apparatus for adjusting gloss of a fused toner image and method for fusing a toner image to a receiver

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 printer for printing color toner images on a receiver member of any of a variety of textures. The printer has a number of tandemly arranged electrophotographic image-forming modules respectively including a plurality of imaging subsystems to form a colored toner image transferred to a receiver member, the transfer of toner images from each of the modules forming a color print of the receiver member which is fused to form a desired color print. The image quality of the color print is produced by control of nonoperational co-optimization of fusing parameters and imaging subsystem parameters enabling printing on the variety of textures of receiver member.
