ABSTRACT:
An image recording apparatus for recording an image directly on a recording medium by transferring a toner to the medium. The toner is caused to fly toward the medium by small energy to form a high resolution image. A developing roller transports the toner in a predetermined direction. A flat electrode is located in the vicinity of the developing roller. A control electrode is provided on the flat electrode at a position where the flat electrode is remotest from the developing roller, while being electrically insulated from the flat electrode. The control electrode is made up of a number of recording electrodes and has an opening through which the toner may fly toward the medium.
