To provide an ink set capable of achieving high scratch resistance and suppression of changes in hand feeling when an image is formed on a fabric, having high maintenance properties and applicable to image formation on a recording paper.SOLUTION: An ink set is to be used for forming an image on a recording medium including a fabric and recording paper, and comprises aqueous ink for inkjet recording and a treating agent. The aqueous ink comprises a pigment, a resin and water, while the treating agent comprises a resin and water, satisfying the following conditions (1) to (3). They are: (1) 0.9≤(B+C)/A, (2) 3≤A≤9, and (3) B<9, where A represents a compounding amount (wt.%) of the pigment in the entire amount of the aqueous ink, B represents a compounding amount (wt.%) of the resin in the entire amount of the aqueous ink, and C represents a compounding amount (wt.%) of the resin in the entire amount of the treating agent.SELECTED DRAWING: None 【課題】 布帛への画像形成において、高い耐擦過性と手触りの変化の抑制とを両立可能で、メンテナンス性が高く、且つ、記録用紙への画像形成にも適用可能なインクセットを提供する。【解決手段】 布帛及び記録用紙を含む記録媒体への画像の形成に用いられるインクセットであって、インクジェット記録用水性インクと、処理剤と、を含み、前記水性インクは、顔料と、樹脂と、水と、を含み、前記処理剤は、樹脂と、水と、を含み、下記条件（１）〜（３）を満たすことを特徴とする。条件（１）：０．９≦（Ｂ＋Ｃ）／Ａ条件（２）：３≦Ａ≦９条件（３）：Ｂ＜９Ａ：前記水性インク全量における前記顔料の配合量（重量％）Ｂ：前記水性インク全量における前記樹脂の配合量（重量％）Ｃ：前記処理剤全量における前記樹脂の配合量（重量％）【選択図】 なし
