Abstract

PURPOSE: To improve resolution of recording image without constraint in processing technique by providing a pair of electrodes arranged on both faces of a substrate for forming an electric field to make a toner pass through a toner passing hole, image information generating means for setting a predetermined electric potential between the pair of electrodes in accordance with image information, and deflecting means arranged in an output side of the toner passing hole for deflecting the toner in a predetermined direction.
CONSTITUTION: A deflecting means 70 is provided with a pair of deflecting plates 71 arranged in an opposed manner in right and left directions at a lower part of a control electrode 25 and a feed means 72 for applying pulse voltage and pulse voltage having a polarity opposite thereto between the deflecting plates. In such a deflecting means 70, when the feed means 72 supplies pulse voltage having positive and negative polarities between the deflecting plates 71, a toner came out from a toner passing hole 22 in response to the polarity of the pulse voltage is deflected in two directions at left side or right side. Thus, the toner can be stuck on a recording paper 60 in a specific direction convergently. Accordingly, resolution of recording image can be improved.
