Drying unit and ejection device

A drying unit comprising:

• a first irradiation device that includes a plurality of first irradiation arrays disposed side by side in a cross direction crossing a feeding direction of a recording medium to which liquid droplets have been ejected and which is being fed, the recording medium being irradiated with laser light by the first irradiation arrays, driving of the first irradiation device being controlled for each of the first irradiation arrays;
• and
• a second irradiation device that includes a plurality of second irradiation arrays disposed side by side in the feeding direction, the recording medium being irradiated with laser light by the second irradiation arrays, driving of the second irradiation device being controlled for each of the second irradiation arrays, wherein:
• the second irradiation device is able to produce a distribution in irradiation intensity of the laser light within an irradiation range of the first irradiation arrays along the feeding direction;
• and
• the first irradiation device is able to produce a distribution in irradiation intensity of the laser light within an irradiation range of the second irradiation arrays along the cross direction.
