Abstract
L'INVENTION CONCERNE UN PROCEDE, UN APPAREIL ET UNE COMPOSITION DE DEVELOPPEMENT D'IMAGES ELECTROSTATIQUES LATENTES. LA COMPOSITION UTILISEE CONTIENT UN LIQUIDE VEHICULE DIELECTRIQUE, DES PARTICULES COLORANTES CHARGEES QUI Y SONT DISPERSEES AINSI QUE DES PARTICULES D'ECARTEMENT DONT LA CHARGE SUPERFICIELLE EST DE LA MEME POLARITE QUE CELLE DES PARTICULES COLORANTES, DONT LA CONSTANTE DIELECTRIQUE EST SUPERIEURE A CELLE DU LIQUIDE VEHICULE ET DONT LE PLUS GRAND DIAMETRE EST INFERIEUR A SOIXANTE-DIX MICRONS. L'INVENTION S'APPLIQUE NOTAMMENT AU DOMAINE DE LA REPROGRAPHIE.
