Abstract
L'invention concerne un appareil de commande du niveau de charge sur la surface photoconductrice d'une machine de reprographie électrostatique. Un générateur à effet couronne charge initialement la surface photoconductrice et l'état de charge est examiné et comparé avec une charge de référence. Dans le cas d'une surcharge, une lampe dont l'intensité est réglée en fonction de la surcharge, s'allume pour réduire la charge tandis que dans le cas d'une sous-charge, un dispositif de charge supplementaire fonctionne pour élever la charge au niveau voulu. Applications aux machines xérographiques.
