<p>An image forming apparatus (1) includes: a printing device (14) which forms an image on a recording medium (22) using ink containing at least pigment, a water-soluble organic solvent, resin particles and water; and a fixing device (18) which makes contact with a surface of the recording medium (22) on which the image is formed and applies heat and pressure to fix the image, wherein a minimum filming temperature (MFT 0 ) of an aqueous dispersion of the resin particles is 60°C or above, and higher than a minimum filming temperature (MFT 25 ) of a dispersion of the resin particles in a mixed liquid combining a water-soluble organic solvent at 25 weight% with respect to the resin particles, and water; and wherein the image forming apparatus (1) further comprises a controller (122) which controls temperature of the recording medium (22) in such a manner that, when the temperature of the recording medium (22) in the fixing device (18) is represented by T, the minimum filming temperature (MFT 25 ) of mixed liquid dispersion of the resin particles satisfies MFT 25 ‰¤ T ‰¤ MFT 25 + 50 (°C), and a coating layer is formed on the recording medium (22), then the temperature of the recording medium (22) is adjusted to or below a temperature at which a coating layer is not broken down.</p> |
