Abstract
Developer mix is regenerated in a manner which removes toner crusts from carrier particles in order to extend the useful time of a developer mix within a developer station of an electrophotographic printing or copying machine. A portion of the developer mix is continuously removed from the main body of developer mix in the developer station and supplied to a regenerator device where the developer particles are swirled and impacted to flake off the toner crust formations. The regenerator device is formed with a discharge opening for removal of the cleaned or regenerated developer mix. The discharge nozzle is connected to a recirculation line through which the regenerated mix is conducted back into the developer station. The regenerator device is further provided with an extraction opening for removing the flaked off crust particles to a separate area, such that crust particle deposits are prevented from building up in the regenerator device.
