ABSTRACT:
In a device and method for developing a charge image on a photoconductor of an electrophotographic printer or copier, a developer chamber is provided having a first and a second end in which at least a portion of the developer is contained. A mixer is provided for thoroughly mixing the developer in the developer chamber. The mixer generates a flow of the developer that is directed from a first end of the developer chamber to a second end. An inlet for developer is provided at the first end of the developer chamber and an overflow is provided at the second end. The developer exits the developer chamber via the overflow when its level in the region of the second end exceeds a prescribed height. A conveyor conveys the developer that has exited the developer chamber at the overflow toward the inlet.
