Zusammenfassung:	To provide an image-formed article having high gradation recognition properties since an image-formed article formed by a prior method for printing by an inkjet method using a luster ink has a problem that gradation is hard to be recognized, an ink set for forming the image-formed article, and an image forming method.SOLUTION: The image-formed article includes: a substrate; a ground layer formed on a surface of the substrate; and an ink layer formed by contacting the ground layer, where the ink layer having a film thickness of 100 nm or more is constituted by aggregating a plurality of dots containing a metal nano-particle, and a plurality of the dots have an average value of maximum values Δ1 of differences of dot heights in a region having a radius of 1/4 dot diameter defined in a dot peripheral direction from a dot center of 20 nm or less.SELECTED DRAWING: None 【課題】従来の、光輝性インクをインクジェット方式で印刷する方法で形成した画像形成物は、グラデーション（濃度差）を視認しにくいという問題がある。従って、本発明はグラデーションの視認性が高い画像形成物、ならびに当該画像形成物を形成するためのインクセットおよび画像形成方法を提供することを目的とする。【解決手段】本発明は、基材と、前記基材の表面に形成された下地層と、前記下地層に接して形成されたインク層と、を有し、前記インク層は、膜厚が１００ｎｍ以上の、金属ナノ粒子を含む複数のドットが集合してなり、前記複数のドットは、ドット中心からドット周辺方向に規定した、ドット径の１／４の半径を有する領域における、ドット高さの差の最大値Δ１の平均値が２０ｎｍ以下である、画像形成物である。【選択図】なし
