PROBLEM TO BE SOLVED: To provide an ink such that a recording medium recorded by an inkjet method and others shows high glossiness and achieves both image fixability and blocking resistance.SOLUTION: An ink comprises a pigment, an organic solvent, water, a wax, and a filler. The filler includes an inorganic extender pigment. When the volume-average particle size of the wax is 1, the volume-average particle size of the filler is 1.2 or more and 3.0 or less.SELECTED DRAWING: None 【課題】本発明は、インクジェット法などにより記録された記録媒体が高い光沢を示し、画像定着性と耐ブロッキング性を両立するようなインクを提供することを目的とする。【解決手段】顔料と、有機溶剤と、水と、ワックスと、フィラーとを含むインクであって、前記フィラーとして無機体質顔料を含有し、前記ワックスの体積平均粒子径を１としたときに前記フィラーの体積平均粒子径が１．２以上３．０以下であることを特徴とするインク。【選択図】なし
