Abstract:
1. A drying device comprising: a drying unit in which a plurality of laser light sources are arranged two-dimensionally and that dries ink placed on a recording medium as a result of ejecting of ink droplets from an ejecting unit by irradiating the ink with laser light; a measuring unit that measures a temperature characteristic, in a conveying direction of the recording medium, of the ink placed on the recording medium; a generation unit that generates, based on the temperature characteristic measured by the measuring unit, a laser light irradiation profile with which the ink temperature will be raised by irradiation with laser light to become higher than or equal to a flex temperature at which the ink temperature starts to flex and then kept in a range that is higher than or equal to the flex temperature and lower than a boiling temperature of the ink; and a control unit that controls the drying unit using the irradiation profile generated by the generation unit.
