Claim Text:
1. A drying device comprising: an irradiation unit that irradiates, with laser light, a printing medium onto which ink droplet have been ejected from a droplets ejecting unit; and a control unit that controls the irradiation unit to dry the ink on the printing medium; wherein the control unit includes a nonvolatile memory storing ink drying temperatures correlated with ink types and thermal deformation temperatures correlated with printing medium types, the control unit acquires from the nonvolatile memory an ink drying temperature corresponding to the ink and a thermal deformation temperature corresponding to the printing medium, the control unit determines an ink target temperature using the thermal deformation temperature of the printing medium as a reference in a case in which the thermal deformation temperature of the printing medium is lower than or equal to the ink drying temperature, and using the ink drying temperature as a reference in a case in which the thermal deformation temperature of the printing medium is higher than the ink drying temperature, and the control unit controls the irradiation it so that a temperature of the ink on the printing medium becomes the ink target temperature.
