Abstract
An apparatus for removing a developer mix containing a magnetic component from a developing station of a non-mechanical printer or copier device. The developing station, at its lower portion, includes a channel-like discharge opening which extends over the full width of the developing station. A magnetic closing device is provided in the vicinity of the discharge opening, and functioning such that in its energized condition, its magnetic field acts on the developer mix to form a plug of developer mix in the region of the discharge opening which closes off the discharge opening. In the de-energized condition, the magnetic closing device releases the discharge opening whereupon the developing station is emptied by the action of a succeeding suction device such as a blower.
