Description
bildungsgerät gehört eine mit einer Hochspannungsquelle 15 verbundene Koronaentladungsvorrichtung 14, optische Einrichtungen 21, 22 und 23, die das von einem zu kopierenden Original 18 stammende Bild zur Belichtung auf die photoleitfähige Schicht 7 des Aufzeichnungsmaterials 12 werfen.education device includes a corona discharge device connected to a high voltage source 15 14, optical devices 21, 22 and 23, which originate from an original 18 to be copied Throw the image onto the photoconductive layer 7 of the recording material 12 for exposure.
Das Aufzeichnungsmaterial 12 wird über die Rollen 10 und 11 von einer Antriebsvorrichtung 13 bewegt,
so daß die über die Optik belichtete photoleitfähige Schicht 7 von der Unterseite des Aufzeichnungsmaterials
12 auf die gegenüberliegende Oberseite gelangt und dort in der üblichen Weise mit
Hilfe einer Tonerentwicklungsvorrichtung 30, 34 entwickelt wird. Nach der Entwicklung wird das so entstandene
Pulverbild bei einer weiteren Drehung des Aufzeichnungsmaterials 12 in einer Übertragungsvorrichtung
25, 35, 36 auf ein Trägermaterial 25 übertragen. Ferner ist eine Reinigungsvorrichtung 27
zur Beseitigung eventuell auf der photoleitfähigen Schicht verbliebener Tonerteilchen vorgesehen.
Das in der Zeichnung dargestellte elektrophotographische Abbildungsgerät ist lediglich ein mögliches
Ausführungsbeispiel, bei dem das neue Aufzeichnungsmaterial verwendet werden kann. Besondere
Vorteile sind mit dem AufzeichnungsmaterialThe recording material 12 is moved over the rollers 10 and 11 by a drive device 13 so that the photoconductive layer 7 exposed via the optics passes from the underside of the recording material 12 to the opposite upper side and there in the usual way with the aid of a toner developing device 30, 34 is being developed. After development, the resulting powder image is transferred to a carrier material 25 with a further rotation of the recording material 12 in a transfer device 25, 35, 36. A cleaning device 27 is also provided for removing any toner particles that may have remained on the photoconductive layer.
The electrophotographic imaging apparatus shown in the drawing is only one possible embodiment in which the novel recording material can be used. Special advantages are with the recording material
ίο z.B. auch dann zu erzielen, wenn im Gegensatz zu dem hier gezeigten Beispiel die Belichtung der photoleitfähigen Schicht nicht unmittelbar, sondern durch den Schichtträger 8 hindurch stattfindet und/oder das Aufzeichnungsmaterial als ein zwei Enden aufweisendes Band von einer Zuführungsrolle aus zugeführt und auf einer Aufwickelrolle aufgewickelt wird.ίο e.g. to be achieved even if in contrast to In the example shown here, the exposure of the photoconductive layer is not done directly, but through the substrate 8 takes place through and / or the recording material as a two-ended Tape is fed from a supply reel and wound onto a take-up reel.
