PURPOSE:To remove toner adhering to a part which is not a plotted part lest it should be fixed, to obtain a high-quality image, to miniaturize a device and to reduce cost by providing at least one charge unit ahead of a hammer pin with reference to a thin film. CONSTITUTION:The hammer pin 25 is ultrasonically vibrated in a direction shown by an arrow A to hammer dots corresponding to the image on a recording paper 2 through the thin film 10. This energy becomes heat energy, and the toner forming the image on the recording paper 2 is fixed on the paper 2. When the part of the paper 2 where the image is not formed reaches the position of the pin 25, a laminating actuator 22 is not driven, so that the toner at the plotted part which is not controlled in the plotted part is not fixed. When the paper 2 where the fixing is finished is carried by the thin film 10 and reaches the position of the charge unit 3, the unfixed toner on the paper 2 is attracted to the film 10 by the unit 3. |
