In a conventional brush cleaner used in xerographic machines, toner is dislodged off the photoreceptor through mechanical forces exerted by the brush. The dislodged toner is transported by the air stream generated in the shroud surrounding the brush. Some of the toner is redeposited back on to the photoreceptor through impact forces when the brush first enters the photoreceptor/brush nip region. Unfortunately, in this region static pressure is above atmosphere (because of brush rotation) unless a large vacuum blower is employed. Thus, this portion of toner remains and adds to reduced cleaning efficiency. Conversely, in some methods desired cleaning efficiency is achieved by providing larger mechanical forces at the expense of photoreceptor life.
