ABSTRACT:
An electrographic development apparatus has a sump for receiving developer material including carrier particles and toner particles. A magnetic brush receives development material from the sump and moves the material into a position relative to an electrostatic image carried on an insulating surface so that toner particles can be transferred to the electrostatic image to develop such image. A ribbon blender in the sump mixes the toner and carrier particles of the developer material, circulates developer material axially within the sump, agitates and shears the developer material, promotes tribocharging, and feeds developer out of the sump along a path leading to the magnetic brush.
