ABSTRACT:
An electrophotographic apparatus constructed with a photosensitive body, a primary charger to apply a substantially uniform primary charge to the photosensitive body, a secondary corona discharger to apply to the photoconductive body either an AC corona discharge or a corona discharge of an opposite polarity to that of the primary charge so as to form an electrostatic latent image on the photosensitive body, the secondary corona discharge application being effected substantially simultaneously with irradiation of an image to be reproduced, wherein the secondary corona discharger is provided with a device to control discharge conditions.
