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.
A device for transferring toner from a transport container into a toner reservoir and from the latter into a developer station of an electrophotographic printer or copier means, whereby a suction nozzle comprising a take-in region having a take-in opening and introducible into the transport container is provided for decanting the toner from the transport container into the toner reservoir by producing a low pressure in the toner reservoir, characterized in that the toner reservoir comprises a settling space that is in communication with the developer station and comprises a suction space separated from the settling space by a filter, said suction space being connected to a means for generating a low pressure to establish an airstream, the filter being fashioned such that, first, it arcs outward under the influence of the airstream flowing therethrough and, second, arcs back again given interruptions of the airstream.
