Claim:
1. An ink jet recording apparatus comprising: a head that ejects droplets of ink in which there is a hysteresis in phase transition temperature and in which a freezing point is lower than a melting point; a flow passage portion for supplying the ink to the head, the flow passage portion including, in a part thereof, a reservoir unit that reserves the ink; and a temperature adjustment unit capable of adjusting temperatures of the flow passage portion and the head independently of each other, wherein the temperature adjustment unit is configured to adjust temperatures of the head and the flow passage portion to turn the ink in the head to liquid after turning the ink in the flow passage portion to liquid, and thereafter, control a temperature of the ink in the flow passage portion to maintain a temperature higher than the freezing point of the ink and lower than the melting point of the ink so that the ink in the flow passage portion does not become solid from liquid in a printing enabled state of the inkjet recording apparatus.
