Abstract

It is proposed to neutralize the charge on a cleaning brush 1 used to remove toner from an electrostatographic imaging sur-face 2- Charge neutralization and pressurization is obtained by blowing ionized air from the inner-core 3 of the brush outwardly through the brush fibers.

It is proposed to neutralize the charge on a cleaning brush 1
used to remove toner from an electrostatographic imaging sur~
face 2~ Charge neutralization and pressurization is obtained
by blowing ionized air from the inner~-core 3 of the brush
outwardly through the brush fibers.

A perforated brush core 4 is provided with the brush bristles
extending radially outwardly therefrom, The perforated core
is arranged to rotate about a stationary core 5. The station~
ary core 5 is pressurized to provide a positive air flow and
includes a corona generating device 6 positioned internally
thereof adjacent an ionized air flow port 7.

BRUSH CLEANER WITH PRESSURIZATION AND CHARGE NEUTRALIZATION
(Cont ~d)

Since the corona generating device 6 is positioned inside the
positive flow cavity of the stationary core 5, it will not be
contaminated by the toner removed by the brush. A low pressure
exhaust 8 is provided for withdrawing the air and toner from
the brush cleaner, Flicker bars 9 and 10 are positioned to
help dislodge the toner particles from the brush fibers. An
air knife port 11 is provided in the housing to also aid in
toner dislodgement.

It is believed that the charge neutralization provided by this
apparatus will help...
