Abstract

SE PRESENTA UN DISPOSITIVO REVELADOR DEL TIPO DE LOS QUE REVELAN UNA IMAGEN LATENTE FORMADA SOBRE UN SOPORTE DE IMAGEN CON UN REVELADOR DEL TIPO DE DOS INGREDIENTES, POR EJEMPLO, UNA MEZCLA DE TONER Y PARTICULAS PORTADORAS MAGNETICAS. EL DISPOSITIVO ES OPERABLE SIN UN MECANISMO DE CONTROL SOFISTICADO DEL CONTENIDO DEL TONER O DE UN MECANISMO AGITADOR Y TRANSPORTADOR SOFISTICADO PARA EL REVELADOR, Y ES CAPAZ DE OBVIAR LOS DIFERENTES PROBLEMAS ADSCRIBIBLES AL INCREMENTO EN EL CONTENIDO DE TONER DEL REVELADOR EN LAS PARTES DE LOS EXTREMOS OPUESTOS DE UN PORTADOR DE REVELADOR. PARA ESTE PROPOSITO, EL DISPOSITIVO RESTRINGE EL MOVIMIENTO DE UN REVELADOR PRESENTE SOBRE EL PORTADOR DE REVELADOR EN LA DIRECCION SUBSTANCIALMENTE PERPENDICULAR A LA DIRECCION EN LA CUAL EL PORTADOR DEL REVELADOR TRANSPORTA EL REVELADOR.
