An object of the invention is to provide an image forming apparatus which can form an image having high quality. The image forming apparatus of the invention at least comprises: a supply section having a toner carrier; a counter electrode disposed facing the toner carrier; a control electrode which is interposed between these toner carrier and counter electrode and which comprises an insulating substrate, a plurality of gates which are formed on the insulating substrate, and two-layer electrode groups composed of a plurality of electrodes individually provided on the peripheries of the plurality of gates; and a control mechanism which can apply a predetermined potential to individual electrodes, the image forming apparatus being constructed in a manner that the predetermined potential is applied to the electrode in a controlled fashion so that the passage of toner through the gate is controlled, and thus an image is formed on a surface of a recording medium fed between the control electrode and counter electrode. Further, the image forming apparatus includes two half-electrode pieces formed by diving each electrode of electrode group on the counter electrode side out of the electrode groups vertically to a paper feed direction, and times of applying a potential to the half-electrode pieces in order to project the toner at a certain angle in a direction vertical to the toner carrier and the counter electrode.
