Description

der Schicht 103 fort in Richtung der Gitterelektrode 108. Nach,Herstellung des Pulverbildes kann dieses unmittelbar auf der aus den Schichten 202 und 103 bestehenden Einheit fixiert.werden. Andererseits ist es möglich, das Pulver. bßld nach einem bekannten Verfahren auf ein weiteres Blatt zu übertragen und auf diesem zu fixieren, um eine Kopie herzustellen. of the layer 103 in the direction of the grid electrode 108. After the powder image has been produced, it can be fixed directly on the unit consisting of the layers 202 and 103. On the other hand, it is possible to use the powder. bßld to be transferred to another sheet by a known method and to be fixed on this in order to produce a copy.

Wesentliche Vorteile, welche sich aus dem vorbeschriebenenVerfahren und Anordnungen nach der Erfindung ergeben, sind, -daß a) alle Vorlagen verwendet werden könngn, bei denen#keine unterschiedlichen Oberflächenleitfähigkeiten vorhanden sind, b) Vergrößerungen und Verkleinerungen der Vorlagen zu erhalten sind, c) anstelle. von Vorlagen mit Aufzeichnungen-auch Gegenstände bzw. andere Objekte zu reproduzieren sind,' d) die vorbeschriebene Vorrichtung schneller arbeitet, als andere bekannte Ausführungen, e)-eine Wiedergabe der Halbwerte (Grautöne) entsprechend denen der Vorlage erfolgt, f) eine Beschleunigung gegenüber den ausschließlich. elektrofotografischen Verfahren erzielt wird infolge einer gleichzeitigen optischen Abbildung und Ausrichtung des Pulvers im elektrischen Feld und g) beliebige Fotoleiter und damit wesentlich billigere . , als die bekannten Halbleiter zu verwenden sind:Significant advantages resulting from the method described above and arrangements according to the invention result, -that a) all templates are used where # there are no different surface conductivities are, b) enlargements and reductions of the originals are to be obtained, c) instead. from templates with records-also reproduce objects or other objects are, 'd) the device described above works faster than other known ones Executions, e) -a reproduction of the half-values (gray tones) corresponding to those of the Submission takes place, f) an acceleration compared to the exclusively. electrophotographic Process is achieved as a result of simultaneous optical imaging and alignment of the powder in the electric field and g) any photoconductor and thus essential cheaper. , as the known semiconductors are to be used:
