Abstract: An image having enhanced cohesiveness is provided by treating the image with heat, ultraviolet radiation or chemical agents prior to transfer of the image from a photoconductor. Treating the developped image improves the efficiency of transfer, reduces the amount of residue remaining on the photoconductor and enables high quality images on a wide variety of substrates to be obtained.

Abstract: Dans un toner liquide destiné aux processus de formation d'images et comportant des particules polymères pigmentées, au moins un directeur de charge et un porteur liquide hydrocarboné de toner, le polymère est un mélange d'au moins deux constituants polymères différents, le mélange étant caractérisé en ce qu'il présente, lorsqu'il se trouve dans un mélange non volatil avec un porteur liquide hydrocarboné de toner, et sur une courbe de refroidissement semilogarithmique de viscosité contre température, un point critique à une température inférieure à environ 65 °C et à une viscosité comprise entre environ 3 x 105 et 5 x 106 centipoises. On a également prévu un mélange de polymères et un processus électrostatique de formation d'images (notamment au moyen d'un élément intermédiaire de transfert) utilisant le toner précité. L'utilisation dans ces processus de ces mélanges de polymères permet l'application de toner liquide à une température égale ou parfois inférieure aux températures traditionnelles de traitement.
