Abstract: A liquid droplet ejecting apparatus includes a liquid droplet ejecting head that includes a plurality of nozzles from which a liquid supplied from a liquid supply source through a liquid supply path is ejected as a liquid droplet, and ejects the liquid droplet from the nozzle to a recording medium to perform a recording process, a first detecting section that detects a vibration waveform of the pressure chamber, which is vibrated when an actuator is driven to cause the pressure chamber communicating with the nozzle to vibrate, to detect a state inside the pressure chamber, and a second detecting section that reads a pattern formed on the recording medium by ejecting the liquid droplet from the nozzle to detect an ejection state of the liquid droplet.
