Abstract
SE PRESENTA UN REVELADOR TIPO DE DOS COMPONENTES, QUE SE SUMINISTRA A UN AREA DONDE SE APLICA UN VOLTAJE DE POLARIZACION DE AL MENOS 250 V, Y UN PROCESO DE REVELADO QUE USA ESTE REVELADOR. EN ESTE REVELADOR, MEDIANTE AJUSTE DE LA DISTRIBUCION DEL TAMAÑO DE PARTICULAS, DE PARTICULAS DE PORTADORA DENTRO DE UNA GAMA ESPECIFICA, SE PUEDE IMPEDIR LA APARICION DEL DENOMINADO FENOMENO DE ARRASTRE DE PORTADORA DE LA TRANSFERENCIA DE LA PORTADORA, JUNTO CON EL COLOR ORGANICO, A UN MATERIAL FOTOSENSIBLE. ESTE AJUSTE DE LA DISTRIBUCION DEL TAMAÑO DE PARTICULA ES DE TAL FORMA, QUE EL CONTENIDO DE PARTICULAS DE PORTADORA, QUE TIENEN UN TAMAÑO INFERIOR A UNA MALLA DE 250, ES INFERIOR AL 8% DEL PESO, BASADO EN LA TOTALIDAD DE PARTICULAS DE PORTADORA, EL DIAMETRO ( ) DEL TAMAÑO DE PARTICULAS DE PESO MEDIO CORRESPONDIENTE AL 50% DEL PESO DE LA TOTALIDAD DE PARTICULAS DE PORTADORA, ESTA EN LA GAMA DE 80 A 120 ( ) Y LA DIFERENCIA ENTRE ( ) Y ( ) ESTA EN LA GAMA DE 5 A 20 ( ).
