Abstract

For decanting toner from a supply bottle into the toner reservoir, an under-pressure is generated in the toner reservoir with the assistance of an exhauster fan. The toner reservoir is connected via a flexible hose to a suction nozzle that can be inserted into the transport container. This suction nozzle is composed of an inside tube that is in communication with the flexible line and of an outside tube that completely surrounds the inside tube at a distance therefrom, this outside tube being open to the environment in its upper part and comprising toner entry openings in its lower part. The air flowing through draws the toner through the toner entry openings. The toner reservoir itself is divided into a settling space and into a suction space, these spaces being separated by a filter. The filter arcs under the influence of the flowing air stream. When it arcs back, the toner adhering thereto breaks off and falls into the settling space.
