Abstract: PURPOSE:To prevent the formation of an image left unscraped on a body to be recorded to remove a sense of aversion of an operator by applying a voltage to a recording electrode before the front end part of a developer layer coated on the body to be recorded reaches the recording electrode. CONSTITUTION:An electric charge is given to a conductive magnetic toner (t) at a point P by application of a developing bias and the toner (t) is stuck uniformly onto a recording sheet 21 by Coulomb force. A stuck toner layer 25 is carried by the insulating recording sheet 21 and passes under a photosensor unit 26. The toner layer 25 reaches a position under a stylus array 29. Consequently, the conductive magnetic toner (t) loses the electric charge in a recording section 33 through the stylus array 29 and is attracted toward the stylus array 29 by the strong magnetic field generated by a fixed magnet 35 and is scraped if a transistor is turned on. Before the front end part of the toner layer 25- reaches the recording section 33, a driver transistor 30 is turned off to complete arrangements to charge the electric charge to the conductive magnetic toner (t).
