ABSTRACT:
The transmittance of ionic dye molecules through a thin electrically conductive high polymer film is controlled to vary between at least two states of the film as selected from among oxidized, neutral and reduced states, such that the ionic dye molecules are transferred onto a recording medium, thereby forming an image. A surface of a substrate having fine pores through which the ionic dye molecules can pass is provided with the thin electrically conductive high polymer film to fabricate a cylindrical printing unit 16, which is provided in a face-to-face relationship with an electrode unit 17 such that a voltage can be applied therebetween. The printing unit 16 is filled with a solution 21 containing ionic dye molecules. When electrodes in the electrode unit 17 are supplied with a potential pattern that brings the electrically conductive high polymer to an oxidized state, the ionic dye molecules are released from the printing unit 16 to form a one-dimensional image on a moving sheet of paper 17.
