Abstract

PURPOSE:To achieve the evening of recording quality and increasing of recording speed by directly heating the toner thereby letting the same be melt-transferred to the medium to be recorded such as plain paper or other. CONSTITUTION:Toner is evenly coated on plain paper 1 throufh corona charging with a toner feeder 2. Next, when voltage below 15V is applied between an electrode pin 34 and a return circuit electrode 35 in a heating head 3 by a voltage control unit 36, the current runs through a high resistance layer 31 from the electrode pin 34 and enters the voltage control unit 36 from the condutive layer 32 and return circuit electrode 35. At the time when the current flows in the high resistance layer 31, Joule heat is generated and this heat is transmitted to the conductive layer 32, whereby the surface of the conductive layer 32 in contact with the toner is heated above the toner melting point. Hence, the toner is selectively heated and fused by controlling the voltage to be applied to the electrode pin 34 by the voltage control unit 36, whereby recording on plain paper is accomplished and this makes it possible to achieve evening of recording quality and increasing of recording speed.
