IPC: B41J2/06
Filed: 1988-09-30
Abstract: PURPOSE:To form a high-quality image with high tone reproduction by controlling either or both of an impressed voltage and a voltage impressing time on an electric field control means. CONSTITUTION:In a developing device 2, plural recording electrodes 13 can be controlled so that the voltage is independently impressed on the electrode and a supporting member 15 is disposed through a gap. By impressing the voltage on the recording electrode 13 so that potential difference may occur between the supporting member 15 and a recording paper 18 when the paper passes through the gap, pigment is adhered onto the recording paper opposed to the electrode. As to the adhesion of a coloring material on the recording paper 18, the impressing time is accumulated and the quantity of the adhering coloring material is increased when the impressed voltage is constant. The higher the impressed voltage becomes, the stronger electric adsorption force is. Therefore, developing density can be continuously controlled by modulating and controlling the voltage impressing time according to image density in a printing control part. Thus, the expression of the tone of density can be accomplished and the high image quality can be obtained.
