Abstract
A liquid droplet discharging apparatus includes: a discharging head having: a liquid channel including a nozzle; and an energy applying part which applies, to liquid inside the liquid channel, discharge energy for discharging a liquid droplet from the nozzle; a signal outputting circuit which outputs signals depending on whether the nozzle satisfies a predetermined discharging performance; and a controller. The controller determines whether the nozzle satisfies the predetermined discharging performance, and estimates viscosity of the liquid inside the discharging head based on: viscosity estimation data in which discharge energy information and viscosity information are associated with each other, and a result of the determination performed in a case that the controller controls the energy applying part based on the discharge energy information and that the discharge energy is thereby applied to the liquid inside the liquid channel.
