Abstract
A development system for a reproduction machine includes a pair of augers which mix and transfer the developer mixture to a magnetic roll brush system. The supply auger is positioned in a horizontal plane; the second return auger is at an angle to the first auger. The first auger transports developer material in one direction mixing the developer material and dispensing developer material along its length by gravity to the magnetic brush roll sump. A developer material transport opening at one end allows developer material to be gravity fed to the adjacent end of the inclined auger which carries the developer material uphill. The developer material is transferred at the other end by gravity feed back to the first auger.
