Abstract

L'INVENTION CONCERNE UN MATERIAU PHOTOCONDUCTEUR DU TYPE ELECTROPHOTOGRAPHIQUE PRESENTANT DES CARACTERISTIQUES PERFECTIONNEES. IL EST CONSTITUE D'UNE BASE ELECTROCONDUCTRICE SUR LAQUELLE EST FORMEE UNE COUCHE PHOTOSENSIBLE, CELLE-CI ETANT CONSTITUEE D'UN ALLIAGE SELENIUM-TELLURE DONT LA CONCENTRATION EN TELLURE EST COMPRISE ENTRE 5 ET 20 ET D'UN HALOGENE DONT LA CONCENTRATION EST COMPRISE ENTRE 5 ET 500PPM, L'HALOGENE ETANT CHOISI DANS LE GROUPE FORME DU FLUOR, DU CHLORE, DU BROME ET DE L'IODE, DANS LA COUCHE PHOTOSENSIBLE, LA CONCENTRATION EN TELLURE ETANT SENSIBLEMENT EGALE OU AUGMENTANT EN DIRECTION DE LA SURFACE DELA COUCHE PHOTOSENSIBLE, ET LE RAPPORT DE LA CONCENTRATION EN TELLURE AU VOISINAGE DE LA BASE ELECTROCONDUCTRICE A LA CONCENTRATION EN TELLURE AU VOISINAGE DE LA SURFACE DE LA COUCHE PHOTOSENSIBLE ETANT DE 65, OU PLUS, A 100. LE MATERIAU DE L'INVENTION PERMET NOTAMMENT D'OBTENIR UN POTENTIEL RESIDUEL REDUIT ET D'AMELIORER LA SENSIBILITE RELATIVE. CE MATERIAU EST DESTINE A ETRE UTILISE DANS UN COPIEUR ELECTROPHOTOGRAPHIQUE.
