ABSTRACT:
The image forming method includes: a treatment liquid deposition step of depositing, on a recording medium, a treatment liquid which reacts with a water-based emulsion-type ink having a water-based ink solvent, a pigment-based coloring material and at least one constituent material of a radiation-curable monomer, a radiation-curable oligomer, and a mixture material of the radiation-curable monomer and the radiation-curable oligomer; an ink ejection step of ejecting the water-based emulsion-type ink by means of an inkjet head toward the recording medium on which the treatment liquid has been deposited in the treatment liquid deposition step; a radiation irradiation step, in a state where the water-based emulsion-type ink has reacted with the treatment liquid on the recording medium after the ink ejection step and an aggregate of the pigment-based coloring material and the at least one constituent material is separated in phase from a liquid component including the water-based ink solvent, of irradiating radiation onto at least the aggregate on the recording medium, to cure the aggregate; and a liquid removal step of removing at least a portion of the liquid component from the recording medium, after the radiation irradiation step.
