Abstract

L'invention concerne un appareil d'impressions par voie électrostatique. Il comporte des moyens d'excitation pour exciter sélectivement des premières et secondes électrodes d'impression en vue de former une image électrostatique sur un support d'impression disposé dans le voisinage desdites électrodes, et agencés de manière à exciter les premières électrodes d'impression sélectionnées pendant une première durée et ensuite les secondes électrodes d'impression sélectionnées pendant une seconde durée. Application aux appareils de reprographie et de fac-similés.
