Patent ID: 7538147

Claim:
An image forming method which imparts two or more kinds of liquid compositions onto a recording medium to form an image on the recording medium, the method comprising the steps of: preparing a plurality of liquid compositions which include at least (a) a first liquid composition containing a functional substance, an anionic amphiphilic block polymer, and a liquid medium, and (b) a second liquid composition containing a functional substance, a polyvalent cation, an anionic amphiphilic block polymer, and a liquid medium; and imparting the first liquid composition and the second liquid composition onto the recording medium to bring the first liquid composition and the second liquid composition into contact with each other to cause at least one of these liquid compositions to thicken, wherein the anionic amphiphilic block polymer in the second liquid composition has a sulfonic acid group as an organic acid group, wherein the anionic amphiphilic block polymer in the second liquid composition contains a dioxyethylene unit structure, and wherein the functional substance in the second liquid composition is enclosed by the anionic amphiphilic block polymer in the second liquid composition.
