ABSTRACT:
A development station for an eletrostatographic apparatus has an elongate sump for a two-component developer material. A feed screw drives developer material along a tube and through openings in the tube into the sump. A ribbon blender coaxially positioned wtih respect to the tube mixes the developer material, delivers it to a developer applicator for transfer to an electrostatic image, and returns the remaining developer material to the other end of the sump for mixture with fresh toner particles.
