Abstract:
1. An apparatus for transporting powder into a developer station containing at least powder and magnetic carrier comprising: a. a development station housing divided into a feed apparatus located adjacent to a development roller and a powder conveyance device; b. the powder conveyance device having a single channel divided into a first mixing space adjacent to a second separate transport space, the second transport space located adjacent to the feed apparatus; the powder conveyance comprising two or more augers each having a shaft; and c. a conveyance controller for controlling the powder conveying device, including the two or more augers, such that the auger preferentially mixes in the first mixing space by minimizing P/F (Push/Flip) and transports in the second transport space as the powder conveying device conveys the powder toward the feed apparatus by maximizing P/F(Push/Flip).
