Die Erfindung betrifft ein Verfahren zur Entwicklung eines Wärmeleitfähigkeitsbildes, das sich auf einer photoleitfähigen Schicht in Übereinstimmung mit einem Ladungsbild befindet, durch Einwirkung von Wärme.The invention relates to a method for developing a thermal conductivity image based on of a photoconductive layer is in conformity with a charge image by exposure of warmth.
Es ist bekannt, photoleitf ähige Schichten elektrisch aufzuladen und in diesen Schichten durch Belichtung ein Ladungsbild zu erzeugen. Zur Entwicklung dieses Ladungsbildes wird die Schicht mit einem Toner bestäubt, der entsprechend dem Ladungsbild an der Schicht anhaftet. Zur Fixierung wird der Toner erwärmt. Dieses Verfahren setzt einerseits einen umfangreichen vorrichtungsmäßigen Aufwand voraus und hat darüber hinaus den Nachteil, daß die Aufbringung des Toners schlecht kontrolliert werden kann. Ferner verteilt sich letzterer in alle Geräteteile, so daß — sofern nicht besondere Schutzmaßnahmen getroffen werden — die Wirksamkeit des Gerätes herabgesetzt wird. Im übrigen ist es verhältnismäßig schwierig, die Tonerteilchen gleichmäßig an das ao Ladungsbild heranzuführen.It is known to charge photoconductive layers electrically and in these layers by exposure to generate a charge image. To develop this charge image, the layer is coated with a toner dusted, which adheres to the layer according to the charge pattern. The toner is used for fixing warmed up. On the one hand, this method requires extensive equipment-related expense and also has the disadvantage that the application of the toner can be poorly controlled can. Furthermore, the latter is distributed in all parts of the device, so that - unless special protective measures are taken - the effectiveness of the device is reduced. Otherwise it is proportionate difficult to bring the toner particles evenly to the ao charge image.
Zur Vermeidung letzterer Schwierigkeit ist bereits Zuflucht zur sogenannten Naßentwicklung genommen worden, bei welcher die das Ladungsbild tragende Fläche einem flüssigen Entwickler ausgesetzt wird, dessen Trägerfiüssigkeit einen so hohen elektrischen Widerstand hat, daß ein Zerfall des Ladungsbildes verhindert wird, und in der ein geladener Toner dispergiert und ein steuernder Stoff enthalten ist. Bei diesem Verfahren muß dann die Trägerflüssigkeit verdampft werden. Zum Aufbringen des flüssigen Entwicklers und zur Verdampfung der Trägerflüssigkeit ist wieder ein vorrichtungsmäßiger Aufwand notwendig, wobei durch die Verdampfung Schutzmaßnahmen für Geräteteile notwendig sind, die nicht in dem Verfahrensschritt der Verdampfung wirksam sind. Im übrigen ist durch dieses Verfahren der ursprüngliche Vorteil einer Trockenentwicklung aufgegeben worden.To avoid the latter difficulty, recourse has already been taken to so-called wet development in which the surface carrying the charge image is exposed to a liquid developer whose carrier liquid has such a high electrical resistance that the charge image disintegrates and in which a charged toner is dispersed and a controlling agent is contained is. In this process, the carrier liquid must then be evaporated. To apply the liquid developer and for evaporation of the carrier liquid is again a device-like Effort necessary, whereby protective measures for device parts are necessary due to the evaporation, which are not effective in the process step of evaporation. Otherwise it is through this procedure the original advantage of dry development has been abandoned.
Aufgabe der Erfindung ist, ein staubfreies, ohne Verdampfung einer Flüssigkeit arbeitendes elektrophotographisches Entwicklungsverfahren anzugeben.The object of the invention is to provide a dust-free electrophotographic that operates without evaporation of a liquid Specify development process.
Das erfindungsgemäße Verfahren geht von der Erkenntnis aus, daß das Ladungsbild auch ein bestimmtes Wärmeleitfähigkeitsbild in der photoleitfähigen Schicht schafft.The method according to the invention is based on the knowledge that the charge image is also a specific one Creates thermal conductivity image in the photoconductive layer.
Gegenstand der Erfindung ist ein Verfahren zur Entwicklung eines Wärmeleitfähigkeitsbildes, das sich auf einer photoleitfähigen Schicht in Übereinstimmung mit einem Ladungsbild befindet, bei dem die das Wärmeleitfähigkeitsbild tragende, photoleitfähige Schicht mit einem Gemisch, von dem beim Verfahren zur Entwicklung eines Wärmeleitfähigkeitsbildes The invention relates to a method for developing a thermal conductivity image which is on a photoconductive layer in accordance with a charge image in which the photoconductive layer carrying the thermal conductivity image with a mixture of which at Process for developing a thermal conductivity image
