摘要： An ink jet method includes a dissolved gas amount control step of controlling a dissolved gas amount of a radiation curable ink jet composition by a dissolved gas amount control unit at least a part of a flow path connecting a container receiving the ink jet composition and an outlet of an ink jet head to which the ink jet composition is supplied from the container; and an ejection step of ejecting the ink jet composition from the outlet of the ink jet head. The ink jet composition contains a polymerizable compound and a polymerization initiator, the dissolved gas amount control unit includes a member formed from an adhesive, and an absolute value (|(σ1)−(σ2)|) of the difference between a mass average SP value (σ1) of the polymerizable compound and a SP value (σ2) of the adhesive, each of which is calculated by Small's formula, is 1.0 or more.
