Abstract

UN TONER ELECTROFOTOGRAFICO PARA LA CARGA DE NEGATIVOS QUE CONSTA DE UNA RESINA POLIESTER COMO RESINA DE FIJACION Y UNA SAL DE AMONIACO CUATERNARIA QUE TIENE UN ANION OXIACIDO COMO ASISTENTE DE CONTROL DE CARGA EN COMBINACION CON UN AGENTE DE CONTROL DE CARGA PARA LA CARGA DE NEGATIVOS Y UN COLORANTE. LA SAL DE AMONIACO CUATERNARIA UTILIZADA COMO ASISTENTE ES INCOMPATIBLE CON LA RESINA DE FIJACION PERO DISPERSABLE EN LA MISMA. EL TONER PROPORCIONA UNA DISTRIBUCION NITIDA DE LA CANTIDAD DE CARGA DE MANERA TAL QUE SE IMPIDA LA FORMACION DE PARTICULAS DE TONER ALTAMENTE CARGADAS QUE NO CONTRIBUYEN AL DESARROLLO Y DE PARTICULAS DE TONER POBREMENTE CARGADAS QUE SE EXTIENDEN CON FACILIDAD.
