Abstract
With the advent of low volume, low cost desk top copiers, a low cost transfer system is needed. The present invention uses a brush having conductive bristles, and a low voltage source, the brush being mounted adjacent to, but not in contact with a photoreceptor. A copy sheet is directed toward the bristles to deflect the bristles so that the bristles are in contact with the back side of the copy sheet as it contacts the toner image on the photoreceptor. Immediately before the trailing edge of the copy sheet moves out of contact with the photoreceptor, the brush is returned to its original position without contacting the photoreceptor.
