1. A drying device that dries a medium being transported, the drying device comprising:
a support that supports the medium being transported;
an AC electric field generation unit that generates an AC electric field;
a detector that detects an amount of moisture contained in the medium; and
a control unit, wherein
the AC electric field generation unit includes:
a first electrode and a second electrode disposed adjacent to each other and facing the medium supported by the support;
a high-frequency voltage generator that generates a high-frequency voltage at the first electrode and the second electrode, and
a conductor that electrically couples the first electrode and the second electrode to the high-frequency voltage generator,
the detector is disposed at least one of downstream or upstream of the first electrode and the second electrode in a transporting direction, and
the control unit controls the AC electric field generation unit in accordance with a detection result of the detector.
