A container for storing a supply of toner particles therein is used in a developer unit of an electrophotographic printing machine. The container has a discharge port connected to a chamber storing the supply of toner therein. A movable member is positioned in the chamber of the container. The movable member includes a planar surface. When the planar surface is positioned remote from the discharge port, the planar surface receives toner particles. When the planar surface is positioned in engagement with the discharge port, toner particles are discharged from the planar surface through the discharge port. In this way, the member functions to seal the toner container when the toner container is in an non-operative position remote from the developer unit, and to meter precise quantities of toner particles to the developer roller of the developer unit when the toner container is in the developer unit in the operating mode thereof.
