Abstract: A liquid supply device includes a first storage unit that stores a first liquid, a second storage unit that stores a second liquid separately from the first liquid, the second liquid containing an infrared absorbing agent, a mixing unit that mixes the first liquid and the second liquid to generate a mixture, and a supply unit that supplies the mixture to an outside of the liquid supply device.

Abstract: Provided is a droplet ejection device, including: a droplet ejection head in which a longitudinal direction thereof is aligned with a width direction of a recording medium and that forms an image by ejecting a droplet onto the recording medium to be transported along a transporting path; and three or more movable infrared ray irradiation devices that are movably disposed on a downstream side of the recording medium in a transporting direction in relation to the droplet ejection head and that evaporate moisture in the image formed on the recording medium.

Abstract: A drying device includes: an irradiation unit that irradiates, with laser light, a printing medium onto which ink droplets have been ejected from a droplets ejecting unit; and a control unit that controls the irradiation unit so that a temperature of ink on the printing medium becomes an ink target temperature that is determined using a thermal deformation temperature of the printing medium as a reference in case the thermal deformation temperature of the printing medium is lower than or equal to an ink drying temperature, and becomes an ink target temperature that is determined using the ink drying temperature as a reference in case the thermal deformation temperature of the printing medium is higher than the ink drying temperature.

Abstract: A drying device includes: a drying unit in which a plurality of laser light sources are arranged two-dimensionally and that dries ink placed on a recording medium by ejecting 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, 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 being higher than or equal to the flex temperature and lower than a boiling temperature or the ink; and a control unit that controls the drying unit using the irradiation profile.

Abstract: A droplets drying device includes: an illuminating unit that applies infrared laser light to droplets that have been ejected onto a recording medium by an ejecting unit that ejects droplets in accordance with an image to be formed; and a control unit that controls at least one of timing, a position or positions, and an amount or amounts of application of infrared laser light to the droplets by the illuminating unit in accordance with an attribute that influences image quality of an image formed.
