Abstract

Un dispositivo de carga por efecto corono mejorado aplicable en sistemas de reproducción xerográfica, caracterizada porque dicho dispositivo incluye: un elemento conductor y un electrodo corona contiguo a dicho elemento, incluyendo dicho electrodo un hilo conductor revestido con un material dieléctrico grueso, siendo el espesor del dieléctrico suficiente para impedir la circulación de una corriente de conducción a través de dicho hilo, estando dicho elemento aislado eléctricamente de dicho hilo, y un dispositivo para aplicar una tensión de corriente alterna generadora de efecto corona a dicho hilo para establecer una descarga de efecto corona en la superficie de dicho electrodo, y un dispositivo para aplicar un potencial de referencia de corriente continua a dicho elemento.
