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 the thin layer to light according to image information, and transferring a part of the photosensitive toner onto a transfer material. The transferring step includes contacting the transfer material with the thin layer after the exposing step as applying a pressure to the transfer material, and irradiating a corona ion from a back side of the transfer material to the thin layer by using a corona charger. Thus, the transfer material is maintained in pressure contact with the thin layer of the toner during the transferring step, thereby improving a transfer efficiency of the toner to the transfer material to obtain a satisfactory image having a high density and no void.
