To provide an ink having excellent fixability and discharge stability.SOLUTION: An ink comprises an organic solvent and a colorant. With a longitudinal axis being a viscosity (mPa s) of the ink at 25°C and a horizontal axis being a reciprocal of an absolute temperature T(K) of the ink, a graph has a gradient (a) of 1.00×104 or more and 2.10×104 or less.SELECTED DRAWING: None 【課題】定着性と吐出安定性に優れたインクの提供【解決手段】有機溶剤及び色材を含むインクであって、縦軸を前記インクの２５℃における粘度（ｍＰａ・ｓ）とし、横軸を前記インクの絶対温度Ｔ（Ｋ）の逆数としたときのグラフの傾きａが、１．００×１０４以上２．１０×１０４以下であることを特徴とするインク。【選択図】なし
