Patent JP-H01262561-A (JP)
Title: Image forming method
Inventor: HANDA TSUNEO
IPC: G03G15/00
Filed: 1988-04-13
Abstract: PURPOSE:To reduce a voltage necessary for image formation to a desired voltage by developing a charge pattern with insulating electric charge grains without an electric conductor on the back side of a dielectric substance. CONSTITUTION:A dielectric film 1 is composed of a first dielectric layer 3 and second dielectric layer 2; conductive and independent microparts 4 are exposed on the surface of the first dielectric layer 3; and the dielectric constant of the second dielectric layer 2 is greater than that of the first dielectric layer 3. A microelectrode 5 is brought into contact with the surface of the dielectric film 1, and the electric conductor 6 is placed in the prescribed gap on the back side of the dielectric film 1; the surface of the dielectric film 1 is scanned while the voltage is impressed in the form of a pulse according to the image which is to be formed; and electric charges are applied to the microparts 4, whereupon the charge pattern is formed. Without the electric conductor on the back side of the dielectric substance, the charge pattern is developed with the insulating electric charge grains. Since only a developing sleeve suffices for the electrode used in development, the lines of electric force between the developing sleeve and dielectric film are concentrated and developing capacity is improved even with a low potential in the charge pattern; thus, writing voltage is considerably lowered.
