A liquid discharge apparatus is provided. The liquid discharge apparatus includes a discharge head that discharges a first liquid supplied via a liquid supply tube from a liquid tank, wherein the liquid tank has a first liquid reservoir chamber that stores the first liquid and a second liquid reservoir chamber that stores a second liquid whose solvent is the same as that of the first liquid and whose concentration is lower than that of the first liquid, the liquid tank is partitioned by a partition wall that partitions an inside into the first liquid reservoir chamber and the second liquid reservoir chamber, and at least a part of the partition wall has liquid permeability and a solvent for the second liquid stored in the second liquid reservoir chamber is capable of permeating the inside of the first liquid reservoir chamber via the partition wall.
