Abstract
A toner transport apparatus for electrographic printing machines that uses the distance between a toner storage container holding a supply of toner material and a developer housing to admix the toner with the developer. A first flexible auger transports the toner from the toner storage container to the developer housing and a second flexible auger transports some of the toner and developer from the developer housing back to the toner hopper where it is mixed with fresh toner.
