ABSTRACT:
The image forming apparatus comprises: an ink ejection device which ejects ink comprising a coloring material dispersed or dissolved in a solvent onto a recording medium; a treatment liquid application device which applies a treatment liquid which produces a charged aggregate of the coloring material by reaction with the ink onto the recording medium, in such a manner that two liquids of the ink and the treatment liquid combine on the recording medium; a conveyance device which causes the ink ejection device and the recording medium to move relatively to each other by conveying at least one of the ink ejection device and the recording medium in a direction substantially perpendicular to a breadthways direction of the recording medium; and a solvent absorbing device which is charged to a same polarity as the aggregate of the coloring material and absorbs the solvent in the ink on the recording medium, wherein: the coloring material and the solvent are separated by reaction of the two liquids which have combined on the recording medium; the solvent is then absorbed by the solvent absorbing device; and the coloring material is then fixed onto the recording medium.
