An ink jet method includes an ejecting step of ejecting a radiation-curable ink jet composition from an ink jet head and an irradiating step of irradiating the ejected radiation-curable ink jet composition with an ultraviolet ray at an irradiation intensity of 3 to 10 W/cm.sup.2 by using a light emitting diode. The radiation-curable ink jet composition contains monofunctional monomers including a nitrogen-containing monofunctional monomer. The amount of the nitrogen-containing monofunctional monomer relative to the total amount of the radiation-curable ink jet composition is 5 to 40 mass %.
