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.

摘要:
A liquid discharge apparatus includes a conveyance path, a liquid discharge head, an ejection tray, and a drying device. A medium is conveyed in the conveyance path. The liquid discharge head discharges liquid onto the medium conveyed in the conveyance path. The medium is ejected to the ejection tray. The drying device dries the medium. The conveyance path includes a first bending portion to bend the medium, with a liquid-applied surface of the medium facing inward. The ejection tray includes a second bending portion to bend the medium, with the liquid-applied surface of the medium facing inward. A curvature of the medium bent by the first bending portion is greater than a curvature of the medium bent by the second bending portion. The drying device dries the medium conveyed in the first bending portion.
