Abstract
L'invention est du domaine de la reproduction d'images en couleurs. Suivant l'invention on utilise une suspension constituée par un mélange de particules électrophotosensibles de plusieurs couleurs. On expose le mélange, entre des électrodes qui établissent un champ inducteur de migration des particules, de manière séquentielle aux diverses composantes chromatiques de l'image à reproduire. Suivant un mode de réalisation de invention, on expose la suspension en des sous-zones distinctes d'une zone d'exposition, associées chacune à une composante chromatique particulière, pour déterminer une migration séquentielle des particules, par couleur. Application à la réalisation d'un appareil électrophorétique de reproduction d'images en couleurs.
