PROBLEM TO BE SOLVED: To provide an inkjet recording device which can obtain an image which can be printed on various substrates and be excellent in a dot shape, a color mixture tolerance, a bleeding tolerance and an image uniformity. SOLUTION: The inkjet recoding device includes an inkjet head part wherein two or more inkjet heads of full line type for discharging two or more sorts of cationic polymerization active energy beam curing type inks are arranged in the conveyance direction of a recording medium, a half-curing process for irradiating the ink (n) with the active energy beam before the ink (n+1) which has been discharged from the inkjet head (n+1) located in the downstream of the inkjet head (n) reaches on the ink (n) discharged from the inkjet head (n) located in the upstream of the conveyance direction of the recording medium concerned reaches the target on conditions that the reaction rate of cationic polymerizing compound measured by FT-IR becomes 17% or more and 35% or less, and a full-curing process which has a full-curing light source for fully curing the ink in the utmost downstream of the conveyance direction.
