Abstract

Procédé pour réapprovisionner en révélateur liquide, et un révélateur liquide obtenu grâce au procédé qui consiste à transférer une première composition, comprenant un liquide transporteur et un directeur de charge, dans le révélateur liquide et à transférer une seconde composition, comprenant des particules de toner, un liquide transporteur et un directeur de charge, dans le révélateur liquide. Le rapport de la quantité de directeur de charge dans la première et la seconde composition est prédéterminé, ce qui permet d'avoir une quantité constante de directeur de charge dans le révélateur liquide lorsque ce dernier est utilisé dans un procédé d'impression électrostatique.
