CONSTITUTION:An ultrasonic vibration generating part 30 is fixed to the mesh screen 20 through a vibration member 31 and transmitted ultrasonic vibration to the mesh screen 20. In response to the picture information signal of the picture information generating means 40, powdery toner is scattered through the mesh screen 20, and a prescribed picture is formed on the recording paper 60 and fixed. The bias voltage of a fixed polarity is applied to the mesh screen 20 by using the means 40 as a counter electrode. By virture of this bias voltage, the toner is held on the screen 20 and prevented from naturally falling. When the bias voltage is 50V or below, fogging is generated due to the natural falling, and when the bias voltage is 1,000V or more, on the contrary, density fails to be insufficient. Thus, the density of the formed picture is high and the unevenness of the density is restrained.
