In a method and system for transport of toner material, a reservoir arrangement containing the toner material is provided with a removal opening for removal of the toner material. The toner material is transported away from the removal opening with aid of a tube-shaped conduit, the toner material being transported in the tube-shaped conduit via an air current. A negative pressure is generated relative to environment pressure at the removal opening via the air current in the tube-shaped conduit. The reservoir arrangement is provided 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. At least the air-permeable and toner-tight region is partitioned airtight from the environment, environment air being supplied to the partitioned region via a dosing nozzle.
