Abstract:
1. An image recording device, comprising: a recording head having a nozzle to discharge an ultraviolet-ray curable ink which is cured as irradiated with ultraviolet rays; and an ultraviolet-ray irradiation device having an ultraviolet light source to generate ultraviolet rays to cure the ultraviolet-ray curable ink, the ultraviolet light source comprising a light emitting diode which generates the ultraviolet rays having an emission wavelength peak in a range between 305 and 375 nm, and a maximum illuminance in a range between 40 and 1000 mW/cm wherein an image is formed by placing the ultraviolet-ray curable ink discharged from the nozzle on a recording medium and by irradiating the ink on the recording medium with ultraviolet rays, and the ultraviolet-ray irradiation device irradiates the ink within 0.001 to 1.0 second after the placing of the ultraviolet-ray curable ink on the recording medium.
