Patent ID: 8215744

Claim:
An inkjet recording apparatus which records an image onto a recording medium by using an ink containing a coloring material, the inkjet recording apparatus comprising: a first treatment agent deposition device including a first treatment agent droplet ejection head which ejects droplets of a first treatment agent through nozzles and deposits the droplets of the first treatment agent onto the recording medium, the first treatment agent having a function of suppressing permeation of liquid into the recording medium; a second treatment agent deposition device which deposits a second treatment agent having at least one of a function of aggregating the coloring material contained in the ink and a function of increasing viscosity of the ink, onto the recording medium; a drying device which dries the second treatment agent having been deposited on the recording medium; an image processing device which converts input image data into dot data; and an ink droplet ejection head which ejects and deposits droplets of the ink onto the recording medium in accordance with the dot data, wherein the first treatment agent contains a non-aqueous liquid which does not produce curl of the recording medium even if permeating into the recording medium, and at least one of a first resin of which particles are dispersed in the non-aqueous liquid and a second resin which is dissolved in the non-aqueous liquid, a glass transition temperature of each of the first resin and the second resin being not lower than 10° C. and not higher than 70° C.
