ABSTRACT:
The image forming apparatus comprises: an ink ejection device which ejects ink through nozzles, the ink containing coloring material; a treatment liquid ejection device which ejects treatment liquid through nozzles, the treatment liquid being a colorless transparent liquid containing infrared-absorbing material and having at least one of an action of insolubilizing the coloring material, an action of aggregating the coloring material, and an action of preventing dispersion of the coloring material; an infrared irradiating device which irradiates infrared light onto the treatment liquid having been ejected from the treatment liquid ejection device; and a treatment liquid determination device which includes a photoelectric transducer having sensitivity to the infrared light.
