Cross Flow Brush and Photoconductor Cleaner

A brush cleaner for an electrophotographic system is described which has a cross-flow of air crated through the brush fibers near the photoconductor surface to improve cleaning efficiency.

The brush cleaner has a close-fitting housing 12 which extends around brush 10 to a position near the photoconductor surface 14 to produce one gap 16. Air enters at gap 16 and flows across the brush, thereby carrying toner cleaned from photoconductor surface 14, as shown by the arrows, to exit at port 18. Port 18 lead into the exit channel formed by curved wall portion 22 which extends substantially parallel to housing 12. A low-level vacuum source is provided at port 24 to exhaust toner-laden air from the cleaner apparatus.

The cross-flow of air and the close fit of housing 12 serve to prevent toner contamination of the cleaner brush 10.
