Filed:

Sep 4, 1992

Appl. No.:

7/941279

Inventors:

Douglas A. Lundy - Webster NY
Kenneth S. Palumbo - Rochester NY
Robert E. Rosdahl - Webster NY

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 2100

US Classification:

355297

Abstract:

A cleaner band stretchably disposed, across the imaging surface width, between two rotating cleaner brushes. The cleaner band is slightly off center and down process from the brush backup roll. The cleaner band acts as a disturber for dislodging large agglomerate residual particles from the imaging surface.

Abstract:

An apparatus for reducing electrostatic charge of particles in a waste container. In one embodiment the waste container is coated with a liquid having a viscosity sufficient to prevent tribocharging between the waste container and the waster toner particles, and to collect toner particles deposited from the cyclone separator into the waste container. Another embodiment describes the use of a flange extending into the waste container to prevent tribocharging that can cause explosions in the waste toner bottle.

Abstract:

A drawn stainless steel magnetic development roll having a coating-free developer-receptive surface, and a process for making a development magnetic roll drawn from stainless steel and having a developer-receptive, non-abrasive integral surface. The present invention provides a process for making a novel magnetic roll by cold drawing stainless steel rolls to have a desired grooved surface finish, diameter, straightness, runout, and other mechanical tolerance requirements.
