Abstract

L'invention concerne un dispositif électrographique. Selon l'invention il comprend une paire d'électrodes opposées 302, 307, 310, qui sont espacées l'une de l'autre pour définir entre elles une région d'enregistrement, un moyen 318 d'application de tension à travers les électrodes, un moyen d'alimentation en support d'enregistrement 300, un moyen 301 pour amener continuellement un révélateur électroconducteur 320 entre l'une des électrodes et une surface du support d'enregistrement, un moyen 303 pour amener continuellement un matériau électroconducteur 312 entre l'autre électrode et l'autre surface du support d'enregistrement, un moyen 304, 305 pour enlever le révelateur en excès et le matériau électroconducteur des surfaces du support d'enregistrement et former ainsi une image révélée, et un moyen 306 pour fixer l'image révélée. L'invention s'applique notamment aux équipements de fac-similé.
