A cleaning brush 10 is mounted to rotate in a tangential direction opposite to that of a photoreceptor 12. Toner removed from the brush by a flicker bar 14 is carried out of the brush housing 16 by a vacuum conduit 18. A study has shown that increased airflow through the brush nip against the direction of movement of the photoreceptor is beneficial to removal of toner from both the brush and photoreceptor. Thus, by directing an independent nozzle 20 at the pre-nip area of the brush, a high vacuum pressure differential is created across the brush nip which induces an airflow rate through the brush nip which is much higher than that in a conventional brush cleaning s ys tem.
