Abstract

In some electrostatic brush cleaners, a detoning roll removes toner from the brush. A grounded metal blade then scrapes the toner from the detoning roll. A floating or biased blade is proposed to replace the grounded blade. The grounded blade provides a current leakage path that reduces the voltage on the detoning roll. The advantage of the floating or biased blade is that a potential difference between the brush and detoning roll is maintained at a constant level.
