Abstract

La présente invention concerne un système de développement à brosse magnétique. Il s'agit d'un dispositif comprenant un manchon tournant et un systeme d'aimants montés dans le manchon dont le champ magnétique s'étend à travers le manchon, des moyens qui amenent une poudre à développer magnétisable et des moyens qui amènent un support, portant une image à développer, en contact avec la brosse de poudre et qui comporte un plan monté avant les moyens d'amenée, dans le sens de mouvement s'étendant sur toute la largeur de travail du dispositif et dont un bord est parallèle à la circonférence de la broche et très rapprochée de celle-ci tandis que le bord opposé est situé à une plus grande distance de la circonférence de la brosse et rejoint les moyens de dosage et d'amenée. Ce dispositif est utile notamment dans les appareils d'électrocopies.
