    摘要： Provided is an ink jet ink containing a coloring material having a buffer region in an ink use range, the ink jet ink being capable of suppressing the occurrence of the deterioration (dissolution) of a heating portion surface in contact with liquid; and the disconnection of wiring for applying a voltage to a heating portion even when long term continuous printing is performed. The ink jet ink is used for an ink jet recording apparatus equipped with a recording head having a heating portion surface in contact with liquid comprising a metal and/or a metal oxide. The ink jet ink contains a coloring material in a content (mass %) of 3 mass % or more with respect to the total mass of the ink jet ink. The coloring material is a colorant having a buffer region in an ink use range, and comprises a compound represented by the following general formula (I) and/or a compound represented by the following general formula (II) H(OCH2CH2)pR5.   General formula (II)
