Abstract
An ink jet recording apparatus according to one exemplary embodiment includes an actuator, a nozzle plate, a supply unit, a discharging unit, and a circulating unit. The actuator includes a pressure chamber which accommodates ink, and changes volume of the pressure chamber. The nozzle plate opens to the pressure chamber and includes a nozzle having a diameter of 20 μm to 40 μm. The supply unit supplies the ink to the pressure chamber. The discharging unit collects the ink from the pressure chamber. The circulating unit circulates the ink in the supply unit, the pressure chamber, and the discharging unit. In the ink, an average particle size in laser diffraction type particle distribution measurement is from 0.4 μm to 6.5 μm, the average particle size is substantially the same as a particle size in 50% integrated value, and a particle size in 90% integrated value is double or less the particle size in 50% integrated value.
