Abstract
Disclosed in an image-forming process which comprises arranging two electrode surfaces, at least one having a curvature face and at least the other being transparent, to confront each other, forming a layer of a photosensitive toner on one of the electrode surfaces, applying a bias voltage so that the polarity of the toner layer-supporting electrode surface is the same as the polarity of charges on the toner and the polarity of the confronting electrode surface is reverse to the polarity of charges on the toner, irradiating the toner layer with light at a part where both the electrode surfaces are contacted with each other through the photosensitive toner layer, and transferring the unexposed toner toward the confronting electrode surface.
