Abstract
A liquid discharge device includes a liquid discharge head to discharge a liquid, a liquid storage portion to store the liquid, a first channel to discharge the liquid from the liquid storage portion via the liquid discharge head, and a second channel to connect a top portion of the liquid storage portion and the first channel, a fluid resistance of the first channel is less than a fluid resistance of the second channel. The first channel extends from a junction between the liquid storage portion and the first channel to a junction between the first channel and the second channel. The second channel extends from a junction between the liquid storage portion and the second channel to the junction between the first channel and the second channel.
