Electrostatic image toning mechanism
 A mechanism for toning electrostatic images has two storage means for developer containing toner of different characteristics, for example, different colors. A rotational applicator rotates in one direction to transport developer from one storage, past the other storage, to a development zone and back to the storage. The applicator moves in the opposite direction to similarly transport developer from the other storage. A shield blocks the unused storage means in each mode. By transporting developer past the unused storage means on the way to the development zone, the developer can simply fall into the appropriate storage means on leaving the development zone.
