To provide a liquid droplet discharging device that effectively removes bubble and foreign substances in a nozzle channel groove by a small amount of cleaning liquid not deaerated enough and that can clean a nozzle formation surface.

The liquid droplet discharging device includes: an inkjet head that discharges liquid droplets from a nozzle; a pressure reducing means that decompresses in the inkjet head; a wiping head that has a wipe blade for wiping out the nozzle formation surface of the inkjet head; and a moving means that relatively moves the wipe blade to the nozzle formation surface. The liquid droplet discharging device also includes a liquid reservoir for reserving liquid in an upper part of the wiping head.
