Abstract

A drying device includes a conveying unit to convey a medium to which liquid is discharged from a discharging head, a hot air blowing unit, a passage forming unit, and an adjusting unit. The hot air blowing unit includes a blowing unit, and a heating unit. The passage forming unit forms, between the hot air blowing unit and a region on a conveyance path of the conveying unit, a circulation path through which air blown from the hot air blowing unit is to be circulated.
