An ink jetting 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, in which, in cases where a dynamic viscosity at 20� C. in the ink composition for recording is eta1 (mm2/s) and a surface tension at 20� C. is gamma1 (mN/m), and the dynamic viscosity at 20� C. in the auxiliary ink composition is eta2 (mm2/s) and the surface tension at 20� C. is gamma2 (mN/m), the following formula (1) and the following formula (2) are satisfied at the same time. eta1@eta2(1) gamma1>=gamma2(2) |
