Abstract

L'invention concerne un dispositif de formation d'images alimentant en toner (2), provenant d'un réservoir (1) de toner, un récepteur (7) d'images par le biais d'un trou (4) de passage, grâce à l'application, aux électrodes de commande (10), de tensions de signal d'image dépendant du signal d'image. Chaque tension de signal d'image consiste en plusieurs tensions d'impulsion correspondant à une gradation du signal d'image et on varie le temps d'application d'une tension de signal d'image en modifiant le nombre de tensions d'impulsion en fonction d'un signal d'image corrigé de manière à changer la gradation d'un signal d'image, et en modifiant la largeur d'impulsion d'une tension d'impulsion. Un processeur (16) de signal d'image envoie différents potentiels de tension ou différents temps d'application de tension à différentes électrodes de commande (10) se trouvant dans des rangées en aval en fonction de signaux d'image correspondant aux électrodes de commande (10) se trouvant dans des rangées en amont, à côté des électrodes de commande (10) qui se trouvent dans des rangées en aval dans une direction parallèle à celle des rangées.
