Abstract
There is provided an image forming method for forming an image on a recording medium which is fabric or recording paper by using an ink set including an ink and a treatment agent. In a case that the recording medium is the fabric, the image forming method includes: applying the treatment agent, which includes a cationic substance and a water-soluble organic solvent, to the fabric in an application amount of the treatment agent per an area of the fabric in a range of 4.7 mg/cm2 to 34 mg/cm2; drying the applied treatment agent and thereby reducing weight of the treatment agent in the fabric to be not more than 50% of the application amount of the treatment agent; and jetting the ink, which includes an anionic dye and a water-soluble organic solvent, onto the fabric by an ink-jet system.
