Abstract

For transporting finely powdered toner material from a reservoir to a delivery opening, a porous bed that forms a down grade is charged with compressed air proceeding from below, whereby the toner material mixes with air to form a liquid-like mixture. This mixture flows along the down grade from the reservoir to the delivery opening.
