Abstract

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Entwicklung eines elektrostatischen latenten Bildes, das sich auf einem beweglichen Bildträger (1) befindet, mit einem nichtleitenden Einkomponenten-Toner. Die Vorrichtung enthält eine Tonerzufuhreinrichtung (3), um Tonerteilchen (5) aus einem Tonerreservoir (4) zu fördern und elektrich zu laden, eine drehbar gelagerte Entwicklungswalze (2) zur Aufnahme der geladenen Tonerteilchen von der Tonerzufuhreinrichtung und zum Transport der aufgenommenen Tonerteilchen in einen Spalt zwischen der Entwicklungswalze und dem Bildträger, und einer Schichtdicke erzeugenden Dosiereinrichtung, die auf dem Weg der Tonerteilchen von der Tonerzufuhreinrichtung zum Bildträger angeordnet ist, zur Erzeugung einer gleichmäßigen Tonerschicht mit einer definierten Dicke und Ladung auf der Entwicklungswalze. Gemäß der Erfindung sind weitere Mittel zur Vergleichmäßigung der Tonerschicht in Schichtdicke und Ladung vorgesehen.
