Abstract:
An electrophotographic system is constituted by an electrophotographic photosensitive member, a charger for charging the photosensitive member to a potential, and an illuminator for illuminating the charged photosensitive member with a light beam to form an electrostatic image thereon. The electrophotographic photosensitive member has a potential-exposure energy characteristic providing an induction energy and a gamma valve varying depending on an electric field intensity induced by the charged potential. The electrophotographic system further includes a controller for controlling the charged potential on the photosensitive member corresponding to resolution and gradation data of an original, so as to optimally reproduce the resolution and gradation, as desired, of the original.
