Abstract

An image-forming method including the steps of forming a thin layer of a photosensitive toner charged to have a given polarity on a conductive drum, exposing said thin layer to light according to image information, and pressing a roller-type electrode against said toner thin layer through a transfer material after said exposing step to transfer a part of said photosensitive toner onto said transfer material. The method further includes the step of continuing contact between said conductive drum and said transfer material after said transfer material passes said roller-type electrode. Accordingly, a sharp toner image having a high density can be formed without the generation of fog.
