Filed:

Feb 22, 1988

Appl. No.:

7/158975

Inventors:

Richard D. Manca - Walworth NY
Thomas R. Hoffend - Webster NY
Don B. Jugle - Penfield NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 1322

US Classification:

430126

Abstract:

An electrophotographic imaging process which comprises the formation of a latent image on a photoconductive imaging member; thereafter developing the image with a toner composition comprised of resin particles, pigment particles, and a sulfur containing organopolysiloxane wax; subsequently transferring the developed image to a suitable substrate; and permanently affixing the image thereto, wherein there result images with an absence of unwanted toner spots thereon.

Appl. No.:

7/737128

Inventors:

Jeffrey J. Folkins - Rochester NY
Don B. Jugle - Penfield NY

Assignee:

Xerox Corporation - NY

International Classification:

G03G 2100

US Classification:

355215

Abstract:

An apparatus in which an elecrostatic latent image recorded on a photoconductive member is developed with developer material stored in a developer housing. The developer material advances along a path of travel to a development zone closely adjacent to the latent image. A cleaner, positioned in the path of the developer material and spaced from the photoconductive member, cleans contaminants from the developer material without impeding the flow thereof. The cleaner has a multiplicity of fibers disposed in the path of travel of the developer material.

Don B. Jugle - Penfield NY
Anthony F. Lipani - Webster NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 1508

US Classification:

118653

Abstract:

An improved filter apparatus for use in controlling emission of airborne toner from a developer housing. The filter apparatus includes a foraminous filter member made of a relatively rigid inert material which does not chemically react with toner. A gasket and cover maintain a tight seal around the filter member.

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 908

US Classification:

430125

Abstract:

A process for cleaning imaging members which comprises applying thereto subsequent to the formation and development of images a composition comprised of resin particles, carbon black particles, magnetite, charge additive, or a mixture of charge additives, and a wax component comprised of polymeric alcohols of the formula CH. sub. 3 (CH. sub. 2). sub. n CH. sub. 2 OH wherein n is a number of from about 30 to about 300, and thereafter removing said composition.

Appl. No.:

7/449682

Inventors:

Don B. Jugle - Penfield NY
Nero R. Lindblad - Ontario NY
Robert S. Pozniakas - Rochester NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 2100

US Classification:

355297

Abstract:

In association with a primary cleaner device, used to remove the preponderance of toner remaining on a charge retentive surface after transfer, a secondary cleaning member is provided, arranged for the removal of toner agglomerates formed by the agglomeration of toner, and toner and debris. The secondary cleaning member is characterized as a thin scraper member arranged at a low angle of attack with respect to the photoreceptor so that a maximum shearing force can be applied by the blade to the agglomerates for removal thereof. A relatively low load is applied to the blade, so that the problems associated with normal cleaning engagement of blades with a charge retentive surface are avoided.

Abstract:

Disclosed is a toner composition comprised of resin particles, pigment particles, and a wax component comprised of polymeric alcohols of the formula Ch. sub. 3 (CH. sub. 2). sub. n CH. sub. 2 OH wherein n is a number of from about 30 to about 300.

International Classification:

G03G 1508

US Classification:

355 3DD

Abstract:

An apparatus in which an electrostatic latent image recorded on a photoconductive member is developed. A supply of developer material comprising at least toner particles and carrier granules is stored and transported closely adjacent to the electrostatic latent image recorded on the photoconductive member. The quantity of developer material being transported to the electrostatic latent image recorded on the photoconductive member is controlled by a metering blade. At least accumulation of toner particles adjacent the blade is prevented and a flow of toner particles away from the blade induced. In this way, the escape of toner particles from the storage chamber thereof is substantially minimized. This invention relates generally to an electrophotographic printing machine, and more particularly to a development system which minimizes the escape of at least the toner particles of the developer material therefrom. In a typical electrophotographic printing machine, a photoconductive member is charged to a substantially uniform potential to sensitize the surface thereof.
