Abstract

A developer design is described which uniformly mixes the return magnetic developer mix with the main developer mix and with the replenishing toner at a lower energy usage in relatively small design spaces. In a magnetic developer system, spreader bar 10 consists of receiving chute 11 and two vanes 12 and 13, each of which is divided further into layers with connecting slots 14 and 15. In operation, the magnetic mix returning from the last developer roll enters chute 11, is separated into two streams through vanes 12 and 13, is further distributed in each vane into additional streams by flowing through slots 14 and 15. The vanes and slots can be adjusted for various ratios of distribution depending on system requirements.

Magnetic Developer Distributor System

A developer design is described which uniformly mixes the return magnetic developer mix with the main developer mix and with the replenishing toner at a lower energy usage in relatively small design spaces. In a magnetic developer system, spreader bar 10 consists of receiving chute 11 and two vanes 12 and 13, each of which is divided further into layers with connecting slots 14 and 15. In operation, the magnetic mix returning from the last developer roll enters chute 11, is separated into two streams through vanes 12 and 13, is further distributed in each vane into additional streams by flowing through slots 14 and 15. The vanes and slots can be adjusted for various ratios of distribution depending on system requirements. Vane 12 is positioned so that the exit magnetic mix deposits essentially on the top of mixing element 16, and vane 13 deposits its portion of the stream into the region where fresh toner is fed from replenisher roll
17. Efficient mixing in relatively small developer spaces is thus attained.
