ABSTRACT:
A method of transferring images produced by liquid developer in a photographic process which comprises applying a corona charging to a photosensitive member after the development of latent images to increase the attaching force of a toner of the developed image to the photosensitive member and remove the liquid developer and transferring the developed image to a copying web. The corona charging may be applied to the photosensitive member at a point, after development, wherein the angle subtended by a vertical line passing through the center of a drum photosensitive member and a line connecting the center of the drum photosensitive member with the point on the surface of the drum photosensitive member to which the corona charging is applied is not larger than 60.degree..
