The control unit calculates an estimated consumption amount of the relay container based on the amount of the ink supplied from the relay container to the recording head, and consumed and the amount of the ink supplied from the terminal container to the relay container, and calculates the amount of the ink supplied from the terminal container to the relay container using the minimum value of tolerance of a supply amount of the depressurizing pump.
