摘要:
A donor structure for developing toner images to an image receiving surface, said structure including a core structure; end caps including journal portions attached to said core structure;a bearing for operatively supporting said donor structure in an imaging device; and electrically isolating coatings carried by said journal portions, said electrically isolating coatings being interposed between said journal portions and said bearings.
摘要:
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 10−10 to about 10−3 ohms-cm.
摘要:
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.
摘要:
A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, a fluorine-containing additive, and a deflocculant to form a coating solution, and b) providing the coating solution on the fuser member to form a fuser member coating, wherein the fluorine-containing additive includes pendant fluorinated groups.
摘要:
A plasma sprayed TiO2 coating is used to remove effluents produced during an electrical charging step using a corona charging device. The plasma spray allows for the application of TiO2 ceramic to an aluminum dicorotron housing. Plasma spray also increases the electrical conductivity of the TiO2 (which is necessary for the dicorotron operation). Plasma sprayed coatings are also porous which aids in the capture and reduction of effluents.
摘要:
A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorinated copolymer surfactant to form a coating solution, and b) providing said coating solution on said fuser member to form a fuser member coating, wherein said fluorinated copolymer surfactant comprises a fluorinated polyether copolymer comprising pendant trifluoroethoxy groups.
摘要:
A fuser component useful in electrostatographic machines is provided, having a substrate, and thereover a coating composition comprising a haloelastomer, such as, for example, a fluoroelastomer, and a deflocculating agent. A fuser component comprising a deflocculating agent exhibits improved properties including, but not limited to, increased gloss and a smoother coating surface with a relatively high adhesive strength. The use of a deflocculating agent also reduces or eliminates the barium sulfate defect.
摘要:
A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a fluorine-containing polysiloxane additive to form a coating solution, and b) providing the coating solution on the fuser member to form a fuser member coating, wherein the fluorine-containing polysiloxane additive has pendant fluorinated groups.
摘要:
A process for producing a fuser member coating including a) adding and reacting a fluoroelastomer, a crosslinking agent, a polar solvent, and a blend of two different fluorinated copolymer surfactants to form a coating solution, and b) providing the coating solution on the fuser member to form a fuser member coating, wherein the blend of two different fluorinated copolymer surfactants includes copolymers selected from the group consisting of fluorinated acrylate copolymers and fluorinated polyether copolymers.
