摘要： A conducting polymer film comprising a substrate comprising a semiconductor having thereon a conducting polymer film capable of being doped with or undoped of an ionic dye molecule. In the image forming process of the present invention, the conducting polymer film is irradiated with light to generate electromotive force so that the conducting polymer film is doped with or undoped of an ionic dye molecule according to the electromotive force to form an image pattern thereon. The ionic dye molecule forming the image pattern is electrochemically released, and then transferred to a recording medium such as paper. The image forming process provides images of good quality at a relatively high printing speed. The image forming process is energy-saving and takes a low running cost. An marking process and marking apparatus using the above image forming process are also disclosed.

摘要： The present invention provides an image forming method which is featured by the advantages such as a high-quality image, a relatively high speed operation, a low running cost, energy saving, resource saving and friendliness to both environments and users.First, there is prepared an image forming medium which comprises on an electroconductive substrate an electroconductive polymer layer capable of taking in and holding an ionic dye as a result of the change in at least two states selected from the group consisting of an oxidized state, a neutral state and a reduced state of the electroconductive polymer and which holds an ionic dye. Next, an image receiving medium, which has OH.sup.- ions having the same polarity as that of the ionic dye held in the electroconductive polymer layer, is brought into contact with the electroconductive polymer layer. Accordingly, there occurs an ion exchange between the ionic dye held in the electroconductive polymer layer and the OH.sup.- ions in the image receiving medium and the ion exchange produces an image pattern of the ionic dye on the image receiving medium.

摘要： An image forming method and an image forming apparatus, wherein a thin film of an electroconductive polymer which holds and releases a dye by means of an electric field enables a construction including a driving circuit, a driving device and an image forming medium to be used for the transfer of an image pattern. The image forming method includes forming a thin film of the electroconductive polymer on an electroconductive substrate, which can take in, hold and release ionic dye molecules in accordance with the change of the state of the electroconductive polymer, that can assume at least two physicochemical states among an oxidized state, a neutral state and a reduced state of the thin film; and bringing the thin film into contact with an image receiving medium. The image receiving medium has suppressed electroconductivity. When a voltage is applied to the thin film holding ionic dye molecules and the image receiving medium between the electroconductive substrate and an image formation controlling electrode, ionic dye molecules are transferred to a localized area, but not to the entire surface, of the image receiving medium.

摘要： 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.
