To provide an ink set which does not cause a solvent shock, has excellent cleaning properties, and can be stably discharged from an ink jet printer head. SOLUTION: It comprises an inkjet ink containing at least a pigment, a dispersant, a binder resin, and an organic solvent and an inkjet ink cleaner. The dispersant has a weight average molecular weight of Md , and the dispersant is dissolved in the inkjet ink cleaner. When the intrinsic viscosity at 25 ° C. is [η d ] (dl / g), M d / [η d ] is 2500 ≦ M d / [η d ] ≦ 6000, and the molecular weight of the binder resin is M b. the intrinsic viscosity when dissolved binder resin in inkjet ink cleaners [eta b] If you (dl / g) and, inkjet inks M b / [η b] satisfies M b / [η b] ≦ 3500 set.
