ABSTRACT:
Dispenser conduit partitions are used to improve the discharge flow of toner particles from a toner dispenser bottle in a host image forming device. A dispenser conduit partition assembly is inserted into the funnel-like dispenser conduit of the toner dispenser bottle. The conduit partition assembly is arranged with multiple partition members. The multiple partition members act to partition the single symmetric dispenser conduit into a corresponding multiplicity of asymmetric dispenser component conduits. As a result, the toner particles are dispensed by the multiple dispenser component conduits to thereby form a corresponding multiplicity of asymmetric toner particle discharge flows, thus reducing toner bridging.
