An ink-discharging apparatus includes a discharge head discharging an ink, of which viscosity is increased by being irradiated with a predetermined energy ray, from a nozzle onto a recording medium; a first light source radiating the predetermined energy ray; and an irradiation mechanism which irradiates an energy ray for increasing the viscosity of the ink to the nozzle. When the energy ray is irradiated to the ink remaining in the nozzle, the viscosity on the surface of the ink is increased to thereby form a film which covers or closes the nozzle. As a result, it is possible, with the film, to prevent the ink located inside the film from leaking out from the nozzle even when any shock is imparted to the body of the apparatus. Further, it is possible, with the film, to prevent the viscosity of the ink, located inside the film, from further increasing.
