ABSTRACT:
The recording apparatus of a type adopting a non-impact recording method comprises a recording electrode and a toner-bearing counter electrode, which are disposed with a predetermined gap therebetween, and recording is performed on a recording sheet, while the sheet is passed through the gap or recording portion, by the toner being attracted from the counter electrode to the recording sheet in accordance with a signal applied to the counter electrode from the recording electrode. On the surface of the counter electrode, in accordance with the invention there are formed an electrically conductive and ferromagnetic base portion and a number of non-conductive and non-magnetic convexities. The toner is deposited only on the base portion by suitable supply and scraper means, without exceeding the height of the convexities. Furthermore, a quenching charger for quenching charges held on the convexities is disclosed and the magnetic poles of each magnet disposed inside the counter electrode are directed so as to avoid the recording portion.
