A liquid discharge apparatus includes a conveyor to repeat conveyance of a recording medium by a predetermined distance and stop of conveyance of the recording medium; a liquid discharge head to discharge a liquid onto the recording medium; an irradiation device disposed downstream from the liquid discharge head in a direction of conveyance of the recording medium, to irradiate, with an electromagnetic wave, the recording medium onto which the liquid has been discharged by the liquid discharge head; and circuitry configured to control the irradiation device to irradiate the recording medium. The circuitry is configured to set a first irradiation amount during the stop of conveyance to a larger value than a value of a second irradiation amount during the conveyance of the recording medium.
