Abstract

En un aparato de revelado xerografico que usa un cepillo magnetico formado de particulas portadoras magneticas, una banda magnetica colocada corriente abajo de la zona de revelado a lo largo de la direccion de movimiento que el fotorreceptor retiene un cepillo pequeno, separado, de particulas portadoras cerca del fotorreceptor. El cepillo actua como una barrera que separa un flujo de aire "sucio" (cargado con particulas de pigmento organico acarreadas por el aire) corriente arriba de la banda, y un flujo de aire limpio corriente abajo de la banda.
