Abstract

A conductive grounded mechanical brush cleaner and a cleaning apparatus employing the conductive brush cleaner is disclosed. The cleaning apparatus is comprised of a housing 1, a conductive brush 2 for disturbing and transporting to a vacuum port 3 and flicker bar 4, debris and toner particles 5. Conductive brush 2 is attached to ground 6 to maintain a neutral bias on the brush at all times. The conductive brush 2 is made conductive by fabricating with, for example, conductive fibers as disclosed in U.S. Patent 4,835,807 referenced below.

CONDUCTIVE GROUNDED MECHANICAL BRUSH CLEANER

( C ont'd)

A conductive grounded mechanical brush cleaner and a cleaning apparatus employing the conductive brush cleaner is disclosed. The cleaning apparatus is comprised of a housing 1, a conductive brush 2 for disturbing and transporting to a vacuum port 3 and flicker bar 4, debris and toner particles 5. Conductive brush 2 is attached to ground 6 to maintain a neutral bias on the brush at all times. The conductive brush 2 is made conductive by fabricating with, for example, conductive fibers as disclosed in U.S. Patent 4,835,807 referenced below.

The conductive brush 2 attached to ground enables brush fibers in motion or at rest to continuously contact the housing 1 without excessive buildup of electrostatic or frictional charge. The charge level on the brush may be measured by electrostatic voltmeter 7 in the absence of the photoreceptor.
