ABSTRACT:
A developer mixing and transporting member is provided which has at least two independent spiral-shaped channels extending around the circumference of the member. At least one of the channels is partly blocked by an element which restricts developer transport through the channel so that developer being mixed and transported within each of the channels is transported at different speeds and is thus rapidly mixed.
