PURPOSE:To prevent the clogging of a nozzle by preventing the solidification of ink caused by the evaporation of the ink remaining in the nozzle by using color ink cured through reaction due to light as the ink of an ink jet type recording apparatus. CONSTITUTION:An ink tank 17 is communicated with a printing head 20 for injecting ink droplets 19 through a communication pipe 18 and, when the printing head 20 receives the pulse voltage from an electronic pulse generating apparatus 21, one ink droplet 19 is injected from an orifice 23. The ink is fixed to recording paper 11 by a fixing apparatus provided in opposed relation to the surface of the recording paper 11 at a position shifted from the flight track of the ink droplet to print a predetermined information pattern. As the ink 16, color ink cured through reaction due to light is used. Light emitted from a light source 27 for emitting light having a wavelength required in curing a photocurable resin is condensed to a reflective mirror having a parabolic surface shape to irradiate the specific surface of the recording paper 11. In addition, the ink tank 17 and the printing head 20 are pref. covered with a black box 29. |
