An improved development station extends the useful life of toner in the housing and increases the number of images developed by the developer supply. The improved development station includes a development station housing having a developer sump, a toner supply for providing toner material to the developer sump, a mixing auger for uniformly blending and charging toner particles provided by the toner supply into developer material, a magnetic roller for receiving the developer material and bringing the developer material into contact with a photoreceptive member, and a magnet for generating a varying magnetic field to restrict flow of the developer material in the development station housing.
