A developer material mixing blender includes a shaft and self-locking segments. Each segment has a hollow hub, an inner ribbon for moving material towards one end, an outer ribbon for moving material in a second stream towards another and opposite end, and an interstream cross-mixing rib for moving material laterally from one to the other of the first and second streams in order to insure good mixing.
