Apparatus and method for filling a toner reservoir by suction

摘要

An apparatus is provided for filling toner from a transport container into a toner reservoir from where the toner is then supplied to a developing station of an electro-photographic printer or copying device contains a toner reservoir which is divided into a settling space and into a suction space. The settling space and the suction space are separated via a filter. For transferring the toner from a transport container into the toner reservoir, the transport container is connected to the settling space via a flexible line. An evacuation pump connected to the suction space generates an underpressure, whereby the toner settles on the filter means of the settling space. A metering device situated at the floor of the settling space conveys the toner to the developing station.
