Abstract

UN APARATO CONFORMADOR DE IMAGEN INCLUYE UN MIEMBRO QUE DEBE CARGARSE PARA TRANSPORTAR UNA IMAGEN ELECTROSTATICA; UNOS ELEMENTOS DE CONTACTO-CARGA PARA CARGAR DICHO MIEMBRO AL ENTRAR EN CONTACTO CON EL; Y UNOS ELEMENTOS REVELADORES DE IMAGEN ELECTROSTATICA TRANSPORTADOS POR EL MENCIONADO MIEMBRO. ESTOS REVELADORES INCLUYEN: UN REVELADOR DE IMAGEN ELECTROSTATICA QUE INCLUYE UN VIRADOR Y UN POLVO FINO INORGANICO HIDROFOBICO. ESTE POLVO NO SOLO MEJORA LA FLUIDEZ DEL REVELADOR Y AJUSTA SU CAPACIDAD DE CARGA SINO QUE EVITA LAS DIFICULTADES DEBIDAS A LA INTERACCION ENTRE EL MIEMBRO CARGABLE Y LOS ELEMENTOS DE CARGA DE CONTACTO EN PRESENCIA DEL REVELADOR RESIDUAL, TALES COMO LOS DAÑOS EN EL MIEMBRO CARGABLE Y EN EL ENGOMADO DEL VIRADOR QUE ACTUA SOBRE EL.
