To provide a liquid droplet discharging apparatus which can carry out high-reliability liquid droplet discharging abnormalities detection resistant to effects of noise, and can detect causes of liquid droplet discharging abnormalities.
There are set a plurality of inkjet heads 100Y-100K for discharging ink in a cavity as liquid droplets from nozzles by driving an actuator by a driving circuit 18, an ink cartridge 22 for storing the ink, and a discharging abnormalities detection circuit 55 for detecting abnormalities of discharging of the inkjet heads 100Y-100K. The discharging abnormalities detection circuit 55 is arranged at the ink cartridge 22 and detects the liquid droplet discharging abnormalities by electrically detecting residual vibration of the actuator.
