ABSTRACT:
Recording medium is disposed in a recording region defined between a pair of electrodes impressed with a signal voltage. Electroconductive toner is supplied between one surface of the recording medium and one of the electrodes and electroconductive material in the form of a powder or liquid is supplied between the other surface of the recording medium and the other electrode. By selectively applying the signal voltage the toner, recording medium and the electroconductive material are charged to selectively deposit the toner and the electroconductive material on the surfaces of the recording medium thus forming a toner image. After removing surplus toner, the toner image is fixed to obtain a permanent record.
