Abstract:
A liquid discharge apparatus includes a conveyance path, a liquid discharge head, and a drying device. A medium is to be conveyed on the conveyance path. The liquid discharge head discharges liquid onto the medium conveyed on the conveyance path. The conveyance path includes a switchback path and an ejection path. The switchback path switches back a conveyance direction of the medium onto which the liquid has been discharged. The ejection path conveys the medium onto which the liquid has been discharged to an ejection port. The drying device dries the medium both on the switchback path and on the ejection path.
