Abstract

EL REVELADOR DE ACUERDO CON LA PRESENTE INVENCION COMPRENDE TONER Y UN PORTADOR QUE TIENE UN MATERIAL PARA NUCLEOS DE CUYA SUPERFICIE ESTA REVESTIDA CON UNA CAPA DE REVESTIMIENTO HECHA DE POLIMERO. LA CAPA DE REVESTIMIENTO TIENE UN VALOR DE RESISTENCIA SUFICIENTE PARA MINIMIZAR LA CARGA ELECTRICA DEL CONTADOR QUE QUEDA EN LA CAPA DE REVESTIMIENTO, Y EL TONER TIENE CUALQUIERA DE LOS VALORES CARACTERISTICOS REQUERIDOS PARA EVITAR QUE LA CARGA ELECTRICA DEL CONTADOR QUE QUEDA EN LA CAPA DE REVESTIMIENTO SE INCREMENTE. EL USO DEL REVELADOR DE LA PRESENTE INVENCION NO EVITA SOLAMENTE LA OCURRENCIA DE LA LLAMADA DISPERSION DEL PORTADOR, CON LO QUE NO SE PRESENTA SUPRESION, PERO TAMBIEN PRODUCE UNA IMAGEN DE GRAN CALIDAD QUE TIENE UNA GRAN DENSIDAD DE IMAGEN INICIAL.
