Abstract

L'INVENTION EST RELATIVE AU DOMAINE DE LA REPRODUCTION ELECTROSTATIQUE. ELLE CONCERNE UN PROCEDE ET UN APPAREIL DE REPRODUCTION DANS LESQUELS UNE PREMIERE IMAGE ELECTROSTATIQUE D'UN ORIGINAL EST FORMEE ET DEVELOPPEE SUR UNE PREMIERE SURFACE PHOTOCONDUCTRICE 14, ET DE SECONDES IMAGES ELECTROSTATIQUES DE L'IMAGE DEVELOPPEE SONT FORMEES DE FACON REPETEE SUR UNE SECONDE SURFACE PHOTOCONDUCTRICE 21 PAR ECLAIRAGE DE LA PREMIERE SURFACE. LES SECONDES IMAGES, QUI PEUVENT ETRE FORMEES A VITESSE ELEVEE SONT DEVELOPPEES ET TRANSFEREES A UN MATERIAU DE COPIE 24. L'INVENTION PERMET LA PRODUCTION A VITESSE ELEVEE DE COPIES MULTIPLES GRACE AU FAIT QUE LA PREMIERE SURFACE 14 EST UTILISEE COMME ORIGINAL EFFECTIF DANS LA REPRODUCTION UTILISANT LA SECONDE SURFACE 21.
