Abstract:

A member for use is a copying device includes at least a substrate and thereon a surface layer comprised of a nitrile-silicone rubber or elastomer. The nitrile-silicone rubber or elastomer provides superior resistance to swelling from solvents such as hydrocarbons found in many developer compositions. The member may have any form, including a belt, plate or drum configuration. The member may be used in the copying device as a fuser member, a pressure member, a transfer member or a transfix member.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 1520

US Classification:

399328

Abstract:

A fuser belt that is used in an electrostatographic printing machine. The fuser belt has a thickness ranging from about 3 to about 20 mils and has a substrate layer and a toner release layer. The substrate layer is composed of a base material and a first thermally conductive additive, wherein the base material is composed of fibers or a polymeric film. The toner release layer is composed of an elastomeric material and a second thermally conductive additive.

International Classification:

G03G015/10

US Classification:

399159, 399161, 399237, 430117, 430 66

Abstract:

An image-bearing article used in liquid contact electrostatic printing (CEP) is formed from polymers that meet the requisite conformance and heat stability for the CEP process. Excessive absorption of toner carrier liquids by the image-bearing article in liquid CEP leads to the deterioration of the image-bearing article and reduces the useful life of the image-bearing article. The absorption of the toner carrier fluid may be controlled by the addition of oxides, silicone elastomers containing phenyl end groups, fluorosilicones or increasing the cross-linking density of the methyl silicones.

International Classification:

G03G 908

US Classification:

430119

Abstract:

A dry electrostatographic process involving the development of the latent image using a semi-dry developer having a solids content ranging from about 50% to about 99% by weight based on the weight of the semi-dry developer, and wherein the semi-dry developer is prepared by a developer preparation process comprising: (i) removing liquid from a liquid developer in an effective amount to yield the semi-dry developer; or (ii) adding a liquid additive to a dry developer containing toner particles ranging in size of from about 1 to 7 microns in an effective amount to yield the semi-dry developer.

International Classification:

B23B 100

US Classification:

82 111

Abstract:

A method and apparatus for securing a drum blank for machining includes inserting a cylindrical mandrel within a bore of a drum blank, introducing a liquid support material into a space between the outer diameter of the mandrel and the inner diameter of the drum blank, and solidifying the support material. Once the support material is solidified, the drum blank is securely held to the mandrel. Machining operations can be performed by mounting the assembly in a lathe. After machining is completed, the support material may be treated so that the mandrel can be removed from the drum blank. The mandrel may then be recycled.
