Abstract (en)

[origin: EP0709747A2] An electrophotographic method in which an electrostatic latent image on a photosensitive material is developed while applying a developing bias voltage of the same polarity as the polarity of the charge of the photosensitive material. The developing bias voltage is higher than a potential that corresponds to a point of intersection (H) between light attenuation characteristics curves (F,G) approximating (a) the zone of large amount of exposure to light and (b) the zone of small amount of exposure to light.
