An image forming method wherein an aqueous dispersion is prepared in a vessel of an apparatus. The aqueous dispersion contains an electrodeposition material including a fine particle coloring material, and a polymer which is chemically dissolved, or is deposited and precipitated, by a change in pH. The electrodeposition material is deposited and precipitated by changing the pH value of the aqueous dispersion in the vicinity of the image supporting surface of the image supporting member. The polymer in the electrodeposition material has both hydrophobic groups and hydrophilic groups, the proportion of number of the hydrophobic groups to the total number of hydrophilic groups and the hydrophobic groups in the polymer is in the range of from 40 to 80%, 50% or more of the hydrophilic groups can reversibly change from hydrophilic groups to hydrophobic groups due to a change in pH value.
