摘要： An ink jet recording apparatus records information by ejecting ink droplets onto a recording medium. The ink jet recording apparatus has a recording head; driving circuits, measuring circuit, and a judging unit. The recording head has ejection outlets and ink liquid passages connecting to the ejection outlets respectively, an electro-thermal converting element being disposed in each of the ink liquid passages, for generating thermal energy for ejecting the ink droplets. The driving circuits drive the electro-thermal converting element to generate the thermal energy enough to eject the ink droplet. The measuring circuit individually measures a resistance value of the electro-thermal converting element when the driving circuits drive the electro-thermal converting element. The judging unit judges presence of an abnormal state in the ink liquid passage according to the resistance value.
