Abstract

SE DESCRIBE UN REVELADOR DE TIPO DE DOS COMPONENTES QUE CONSTA DE UN COLOR ORGANICO QUE TIENE UNA ELECTROCONDUCTIVIDAD INFERIOR A ( ), EN EL QUE SE USA UNA RESINA DE SILICONA QUE CONTIENE UN GRUPO DE AMINO COMO LA RESINA DE RECUBRIMIENTO PARA UN TRANSPORTADOR MAGNETICO. USANDO LA RESINA DE SILICONA QUE CONTIENE GRUPO DE AMINO COMO LA RESINA DE RECUBRIMIENTO PARA EL TRANSPORTADOR MAGNETICO, SE IMPIDE LA REDUCCION DE LA DENSIDAD DE IMAGEN PROVOCADA POR UN COLOR ORGANICO DE ELECTROCONDUCTIVIDAD MAS BAJA, E INCLUSO EN UN REVELADOR DE COLOR PARA EL QUE SE USA UN COLOR ORGANICO DE ELECTROCONDUCTIVIDAD MAS BAJA, PUEDE FORMARSE UNA IMAGEN DE ALTA DENSIDAD. DE ACUERDO CON UN PROCESO DE REVELADO QUE UTILIZA ESTE REVELADOR, ES POSIBLE EL REVELADO INCLUSO BAJO UNA CONDICION DE VOLTAJE DE ALTA POLARIZACION, Y PUEDE FORMARSE UNA IMAGEN DE GRAN CALIDAD QUE TENGA UNA ALTA DENSIDAD.A TWO-COMPONENT TYPE DEVELOPER IS DESCRIBED CONSISTING OF AN ORGANIC COLOR THAT HAS AN ELECTROCONDUCTIVITY LESS THAN (), IN WHICH A SILICONE RESIN CONTAINING A GROUP OF AMINO IS USED AS THE COATING RESIN FOR A MAGNETIC CONVEYOR. USING THE AMINO GROUP CONTAINING SILICONE RESIN AS THE COATING RESIN FOR THE MAGNETIC CONVEYOR, REDUCING THE IMAGE DENSITY CAUSED BY A LOWER ORGANIC ELECTROCONDUCTIVITY COLOR, AND EVEN IN A COLOR DEVELOPER FOR WHICH IT IS USE A LOWER ORGANIC ELECTROCONDUCTIVITY COLOR, A HIGH DENSITY IMAGE MAY FORM. ACCORDING TO A DEVELOPMENT PROCESS USING THIS DEVELOPER, DEVELOPMENT IS POSSIBLE EVEN UNDER A HIGH POLARIZATION VOLTAGE CONDITION, AND A HIGH QUALITY IMAGE MAY BE FORMED THAT HAS A HIGH DENSITY.
