Method for regenerating the carrier particles of a two-component developer consisting of carrier particles and toner

摘要

Developer mix is regenerated in a manner which removes toner crust 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 developer mix is continuously or periodically removed from the main body of developer mix in the developer station and supplied to a regenerator device where the developer particles are exposed to impacts flaking off the toner crust formations. The regenerated developer mix is then recycled back to the main body of mix at the developer station. This regeneration and recycling of developer mix serves to hold substantially constant the efficacy of the developer mixture.
