ABSTRACT:
The image forming method for forming a desired image on a recording medium, includes the steps of: applying a first liquid on the recording medium, the first liquid containing no coloring material and having a dynamic surface tension at a surface age of 0.1 seconds measured at 25° C. of γ1(0.1 s); and then depositing droplets of a second liquid on a region of the recording medium where the first liquid has a form of a liquid film, the second liquid containing coloring material and having a dynamic surface tension at a surface age of 0.1 seconds measured at 25° C. of γ2(0.1 s) that is greater than γ1(0.1 s).
