摘要：A toner system for delivering powder toner from a storage hopper to an element carrying an electrostatic pattern of charge to be toned before transfer to a receptor such as paper includes a scavenger which, when coupled to the toner system can be actuated to develop a slight negative pressure in the toner system sufficient to entrap flow enhancers such as zinc stearate and to remove the non-magnetic zinc stearate from the toner system. The scavenger includes baffles for collecting particles and means for developing the negative pressure in the toner system. The toner system also includes a pair of magnetic clips for positioning on the metering blade of the toner system to define the width of the toner path being transfered from the toner system to the electrostatic image on the dielectric surface and a cleaning device which periodically moves along the metering blade to clean the front of the metering blade of any accumulated toner.
