Liquid ejection apparatus capable of suppressing temperature drop of humidified air supplied to sealed space along nozzle surface

A liquid ejection apparatus, comprising:

• an ejection portion having a nozzle surface on which nozzles are formed and configured to eject liquid from the nozzles;
• a sealing portion configured to seal a space along the nozzle surface;
• a tank configured to store water;
• a heater configured to heat the water stored in the tank;
• a path forming portion configured to form a movement path for air to move from a first opening portion that opens above a water surface of the water stored in the tank, through a sealed space sealed by the sealing portion, to a second opening portion that opens below the water surface;
• and
• a pump configured to move air in the movement path in a direction from the first opening portion toward the second opening portion;
• wherein
• the first opening portion and the second opening portion are arranged in a positional relationship such that the first opening portion faces a specific range on the water surface to which air discharged from the second opening portion rises.
