The present teachings include a flow coating solution, a fuser member and an image forming apparatus. The fuser member includes a substrate and flow coating solution applied onto the substrate. The outer layer includes a flow coating solution including a fluoroelastomer, a nucleophilic crosslinking agent and a non-functional polydimethylsiloxane having the formula: wherein n is from 100 to 20,000. The flow coating solution includes an effective solvent selected from the group consisting of N-methyl 2-pyrrolidone, dimethyl formamide, and dimethyl sulfoxide.

Fuser, method of fuser manufacture and composition

An apparatus and method of manufacturing a fluorosilicone composite for a variable data lithography imaging member surface layer. Examples of the fluorosilicone composite include a first part and a second part, the first part having fluorosilicone, carbon black, silica and butyl acetate, the second part having a platinum catalyst, a crosslinker, butyl acetate and an inhibitor. The first part may also include a dispersant (e.g., a polyoxyalkylene amine derivative) that removes a need for shaking the dispersion by paint shaker and instead allows a more manufacture friendly roll ball milling process. The dispersant will also help in stabilizing the fluorosilicone composite for scaled up production.

Fluorosilicone composite and formulation process for imaging plate

A multilayer imaging blanket comprises a seamless belt. A silicone layer is disposed on the belt. The silicone layer comprises silicone rubber and a metal oxide filler. A fluoroelastomer surface layer is disposed on the silicone layer. Printing apparatuses employing the multilayer imaging blanket are also disclosed.

Multilayer imaging blanket coating

An apparatus and method of manufacturing a multiplayer image blanket with a platinum catalyzed fluorosilicone topcoat for a variable data lithography printing system. The blanket consists of multiple layers that may be: (A) a commercial carcass having a Sulphur free rubber outer layer, a suitable primer layer for improving the inter-layer adhesion, and the platinum catalyzed fluorosilicone topcoat; or (B) seamless polyimide substrate coated with a platinum cured silicone, a primer layer, and the fluorosilicone topcoat.

Imaging plate multi-layer blanket

This invention provides a mandrel used to produce belts where materials are cured onto a belt. Specific examples for illustration purposes are directed to a mandrel used to produce fuser belts for use in electrophotographic marking systems. The mandrel provides for reduced heating temperature during the curing heating step because the only mass required to be heated during curing is the belt and not the prior art solid mandrel. This provides significant advantages, such as faster cycle time, less energy, and less degrading of layer materials. The present mandrel comprises two terminal caps connected by threaded rods around which the belt is positioned for coating and curing.

Mass-less belt mandrel

An apparatus comprises a frame having a first frame section connected to a second frame section. The frame also has at least one physical connection that allows the first frame section to move relative to the second frame section. A first roller is connected to the first frame section. The first roller has a crowned outer surface surrounding an axle. Also, first connectors connect the first roller to the first frame section. The first connectors allow the first roller to rotate around the axle and allow the first roller to move in a direction parallel to the axle. A second roller is also connected to the second frame section. At least one biasing member is connected to the first frame section and the second frame section. The biasing member applies a bias to cause the first frame section to move away from the second frame section. A belt substrate contacts the first roller and the second roller. A latch is connected to the first frame section and the second frame section. The latch allows the frame to collapse by moving the first frame section toward the second frame section and disconnecting the biasing member.

Self-centering belt support feature

Fixing belts, fixing devices and methods of making fixing belts are provided. An exemplary embodiment of the fixing belts includes an inner layer comprising a first surface forming an inner surface of the fixing belt and a second surface opposite to the first surface, the inner layer comprising a first polymer; an intermediate layer overlying the second surface of the inner layer, the intermediate layer including a third surface, a first end face and a second end face opposite to the first end face, the intermediate layer comprising silicone rubber; and an outer layer including a fourth surface forming an outer surface of the fixing belt, the outer layer overlying the third surface, the first end face, the second end face and portions of the second surface disposed outward from the first end face and second end face, the outer layer comprising a second polymer. The outer layer seals and protects the intermediate layer from exposure to a liquid release agent applied to the fourth surface.

Release-agent-resistant fixing belts, fixing devices and methods of making fixing belts

This is a mandrel used to fabricate seamless belts including those used in electrophotographic marking systems. The mandrel has a center core unit with two circular caps on each side. In between the caps is sandwiched a deformable O-ring which is outwardly deformed upon tightening of the two caps together. Once a tubular sheet is placed over the mandrel, the elastomeric O-ring will hold the sheet in place for further processing.

Expandable belt mandrel

A method of forming a fuser member with an intermediate adhesive layer is provided, wherein the fusing member comprises, in order, a base member, a cured liquid silicone rubber substrate layer, an amino silane, and an anhydrous solvent containing the adhesive layer. The fusing member further comprises a fluoroelastomer fusing surface topcoat layer including poly (vinylidene fluoride-tetrafluoroethylene- hexafluoropropylene).

The invention is directed to self-regenerative, polymeric coatings and methods of using the coatings in xerography to increase the life and effectiveness of catalytic surfaces, such as, for example, charging device surfaces, by neutralizing ozone and nitrogen oxide species.

Self-regenerative xerographic coatings

A process for producing a charging member by grit blasting a charging member substrate, plasma spraying a single component outer coating consisting essentially of titanium dioxide powder directly to the grit blasted stainless steel substrate, and the outer coating has a resistivity of from about 10to about 10ohms-cm.

A roller includes a core and a ceramic coating formed over the core. The roller has a composite runout of less than 20 &mgr;m and a total indicator reading runout of less than 7 &mgr;m. The ceramic coating has a smooth finish and has controlled electric properties. This roller can be used as a donor roller for transporting toner to a photoconductive member so as to achieve high-quality image development.

Donor rolls and methods of making donor rolls

A development apparatus includes a housing defining a chamber holding a supply of two-component developer material including toner, and magnetizable carrier beads. The development apparatus also includes an increased reliability roller assembly within the housing for repeatably transporting a desired quantity of attracted developer material through a development zone. The roller assembly includes a first and a second preformed end cap sections each having a stub shaft portion and a cylindrical capping portion connected to the stub shaft portion and having an outer surface and assembly recesses formed into the outer surface. The roller assembly also includes a sleeve section connecting the first and the second preformed end cap sections, the sleeve section being spincast as a layer over each of the cylindrical capping portions, and into the assembly recesses of the end cap sections, so as to precisely and reliably assemble each capping portion, to the sleeve section.
