Zusammenfassung:Provided is discharging device including liquid droplet discharging unit configured to discharge liquid droplet containing a light-emitting particle that undergoes luminescence in response to irradiation of light, light irradiating unit configured to irradiate liquid droplet discharged by liquid droplet discharging unit with the light, light detecting unit configured to detect luminescence by light-emitting particle contained in liquid droplet in response to irradiation of the light emitted by light irradiating unit, and average particle number calculating unit configured to determine presence/absence of light-emitting particle in liquid droplet based on whether light detecting unit has detected luminescence by light-emitting particle, and calculate average particle number, which is average, among all liquid droplets discharged, in number of light-emitting particles contained per liquid droplet, based on ratio of liquid droplets containing no light-emitting particle relative to all the liquid droplets discharged, the ratio being calculated based on the presence/absence of light-emitting particle.
