Previously, the toner was mechanically transferred from the cleaning to the developer station of an electrophotographic copier by means of an auger. To prevent the toner from caking and packing during this process, it is proposed to replace the auger by an ejector and to transfer the toner by the suction/pressure occurring at the ejector.
