ABSTRACT:
A voltage is applied between a first and second electrode, the first electrode being immersed into an aqueous solution in which a group of two or more dyes having different polarities, and including at least one dye able to be independently precipitated from this aqueous solution by an electrochemical reaction, are dissolved and coexist at a specified pH, and the second electrode being provided so as to cooperate with the first electrode in causing the electrochemical reaction, thereby forming a first mixed color image which is composed of the group of dyes, or another mixed color image whose colors are different to those of the first mixed color image and which is composed of the group of dyes, or a single color image which is composed of a single dye on the electrode. Thus, it is possible to realize a high quality image using dyes and safely and simply record an image at a high levels of flexibility. It is also possible to adjust the density of an image easily, and reduce the effects on the environment and energy consumption.
