摘要:
An inkjet recording apparatus includes: a recording head including an introduction section, a discharge section and nozzles; a first liquid chamber connected to the introduction section; a second liquid chamber connected to the discharge section; a first buffer tank which is connected to the first liquid chamber and an interior of which is open to air; a second buffer tank which is connected to the second liquid chamber and an interior of which is open to air; and a pressure control device which sets target pressures of the first liquid chamber and the second liquid chamber in such a manner that a prescribed back pressure is applied to the liquid inside the nozzles of the recording head while a prescribed pressure differential is provided between the first liquid chamber and the second liquid chamber, and controls driving of the first pump and the second pump in accordance with determination results of the pressure determination device in such a manner that the internal pressures of the first liquid chamber and the second liquid chamber remain constant at the target pressures, wherein the first buffer tank and the second buffer tank are connected via a flow channel, and at least one of a filter and a deaeration device is provided in the flow channel.
