Abstract
In an electrophotographic process in which a photosensitive member such as CdS.nCdCO.sub.3 -resin photosensitive member having peculiar hysteresis characteristics is sequentially subjected to pre-charging step, hysteresis charging step, hysteresis exposure step, charging step and image-wise light exposure step, the adjustment of photosensitivity of the photosensitive member by variation of the amount of light in the hysteresis exposure step results in an improvement in image formation.
