ABSTRACT:
In a xerographic development apparatus using a magnetic brush formed from magnetic carrier particles, a magnetic strip disposed downstream of the development zone along the direction of motion of the photoreceptor retains a separate, small brush of carrier particles near the photoreceptor. The brush acts as a barrier separating a flow of “dirty” air (laden with airborne toner particles) upstream of the strip, and a flow of clean air downstream of the strip.
