Abstract:
An image forming method, comprising:preparing an aqueous dispersion containing an electrodeposition material including: a coloring material; and a polymer which is chemically dissolved, or deposited and precipitated, by a change in pH, in a liquid in vessel; wherein the vessel having therein: an image supporting member including at least: an electrode, which can supply current or an electric field in accordance with an image pattern, and a surface which can support an image; and a counter electrode which forms a pair of electrodes together with the electrode; depositing and precipitating the electrodeposition material including the coloring material and polymer to form an image by supplying current or an electric field in accordance with an image pattern to the image supporting member and the counter electrode and by changing the pH value of the aqueous dispersion in the vicinity of the image supporting surface of the image supporting member; wherein the aqueous dispersion contains at least one pH regulator having a boiling point of 150Â° C. or less.
