<p>PARTIALLY SUBMERGED ACTIVE CROSSMIXER An active crossmixer comprising a pair of rotatably driven augers and a baffle for partially submerging the augers in developer is mounted in the development system of an electrostatic processor above the sump in a position to intercept the developer returning from the development zone and any additional toner added to maintain the toner concentration at a suitable high level. The developer is divided between the augers which, in turn, laterally transport the developer in opposite directions. Preferably, the baffle is apertured so that developer not only flows over the ends of the baffle but also through the baffle, thereby distributing the developer across the full width of the sump.</p> |
