Abstract

Se describe un aparato que hace avanzar el material de revelado hacia una imagen latente electrostática registrada sobre un miembro fotoconductor. El aparato usa un rodillo magnético que tiene un miembro tubular de rotación con un magneto estacionario en el interior de éste, para atraer al material de revelado hacia el mismo. El magneto es substancialmente en forma de V y genera un campo magnético fuerte sobre una región para sujetar el material de revelado sobre el miembro tubular, y un campo magnético débil sobre la región remanente para liberar el material de revelado del mismo. Sobre las patas del magneto se aplican polos magnéticos de polaridad opuesta. Una cuchilla de ajuste, colocada adyacente al miembro tubular opuesto de uno de los polos magnéticos, ajusta el espesor del material de revelado conforme éste está siendo cargado sobre el miembro tubular.
