Abstract
In a rotating cleaning brush apparatus of an electrographic copier having a housing defining a chamber which partially encloses the cleaning brush, a plurality of airflow dividers are disposed within the chamber. These dividers form channels extending from a position adjacent to the rotating brush into an outlet port of the chamber. The outlet port is coupled to a source of vacuum. Airflow is established across the length of the brush and entrains toner and carries it into the channels at sufficient velocity to transport toner from the chamber.
