Abstract:
1. A method for transport of toner material from a reservoir arrangement, comprising the steps of: providing the reservoir arrangement containing the toner material with a removal opening for removal of the toner material; transporting the toner material away from the removal opening with aid of a tube-shaped conduit connected at least with the removal opening, the toner material being transported in the conduit via an air current; generating a negative pressure relative to environment pressure at the removal opening via the air current in the conduit; providing the reservoir arrangement with at least one air-permeable and toner-tight region through which air is sucked into the reservoir arrangement upon application of the negative pressure; and partitioning at least the air-permeable and toner-tight region airtight from the environment, environment air being supplied to the partitioned region via a dosing nozzle.
