An apparatus and method for distributed mixing and transport of toner and powders in an electrostatographic printer containing at least powder and magnetic carrier. The apparatus includes a powder conveying apparatus for transporting powder in a developer station including a development station housing having two or more auger assemblies, each auger assembly including two or more screw augers supported in a channel profile. The two or more screw augers having multiple intermeshed screw blades and controlled by a conveyance controller. The conveyance controller is in communication with the powder the one or more augers, such that each auger preferentially mixes and transports in a first or second direction as the powder conveying device conveys the powder in the developer sump of a print engine.
