PROBLEM TO BE SOLVED: To provide an inkjet ink set excellent in cleaning properties of an ink flow path and in discharge stability.SOLUTION: This inkjet ink set includes: an ink composition for recording supplied to and used in an ink flow path and containing at least one of a glitter pigment and a metal oxide as a coloring material; and an auxiliary ink composition used in cleaning of the ink flow path. When viscosity at 20°C is &eegr;(mPa s) and surface tension at 20°C is γ(mN/m) in the ink composition for recording while viscosity at 20°C is &eegr;(mPas) and surface tension at 20°C is γ(mN/m) in the auxiliary ink composition, the following formulas (1) and (2) are satisfied at the same time: &eegr;≤&eegr;(1), and γ>=γ(2). |
