Crosslinkable Polymer Compositions For Donor Roll Coatings

View page

US Patent:

6340528, Jan 22, 2002

Filed:

Jan 19, 2000

Appl. No.:

09/487288

Inventors:

Bing R. Hsieh - Webster NY
Yuan Yu - North Billerica MA
Timothy J. Fuller - Pittsford NY
John F. Yanus - Webster NY
Damodar M. Pai - Fairport NY
Heiko Rommelmann - Webster NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B23B 2736

US Classification:

428412, 428325, 428327, 428332, 4289231, 428447, 4289735, 4284794, 428480, 428500, 428906, 4289088, 399 3, 399 63, 492 18, 492 53

Abstract:

A donor member, useful in ionographic or electrophotographic apparatuses and preferably useful in hybrid scavengeless development units, has a substrate and an oxidized transport coating thereover. The oxidized transport coating includes a polymer binder, charge transporting molecules and one or more oxidizing agents. The polymer binder of the donor roll coating preferably includes one of (1) a crosslinked polymer with charge transporting molecules dispersed therein, or (2) a crosslinked polyamide binder with hydroxy charge transport molecules dispersed therein. The donor roll is preferably included in a printing machine that develops latent images formed on a photoconductive member.

US Patent:

6548154, Apr 15, 2003

Filed:

Nov 28, 2000

Appl. No.:

09/722513

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B32B 702

US Classification:

428212, 428220, 428323, 428329, 428332, 428339, 4284231, 4284235, 4284237, 4284242, 4284744, 4284752, 4284758, 428515, 428906, 428931

Abstract:

A bias transfer member or bias charging member for a xerographic device includes a support substrate, and a multi-layer conductive surface coating over the support substrate. The multi-layer coating includes a base layer of metal-containing particles in a polymer binder, an intermediate layer of conductive particles in a polymer binder, and a top layer of conductive particles in a polymer binder, wherein the amount of the conductive particles in the top layer is greater than the amount of the conductive particles in the intermediate layer. The multi-layer coating exhibits ideal electrical and abrasion resistance performance for use in bias charging or transfer members.
