Abstract
A two-compartment container for supplying toner to an electrostatographic development station has a first compartment for containing and supplying fresh toner or toner mixed with carrier to the station and a second compartment for receiving and containing spent developer for disposal. When the container is mounted in a toner supplying position with respect to a development station, an opening in the second compartment mates with an opening in the station through which developer overflows. A door covering the opening to the second compartment is automatically openable by appropriate means associated with the station in response to placing the container in the toner supplying position.
