摘要

A filling device dosed to the development station (11) of an electrophotographic printer with toner contained in a reservoir (15) comprises a metering roll arranged at the outlet of the toner container (15). A hollow feed spiral (20) arranged in a feed tube (24) above the metering roller (16) extends parallel thereto until the interior of the toner reservoir. Depending on the desired dosage, the feed spiral (20) and the metering cylinder (16) have a coupled drive.
