摘要：
An exposure means is provided between a development region and a carrier stripping drum that removes carrier particles, being provided inside the developer station of a non-mechanical fast data printer means. The exposure means illuminates and thereby discharges the highly charged and non-toner-covered regions of the surface of a charge image carrier. The adhesion of negative carrier particles of the developer mix to the non-exposed regions of the surface of the charge image carrier is thus reduced, so that they can be easily stripped from the surface of the charge image carrier by the following carrier stripping drum.
