  • Publication number: 20240100854
    Abstract: To provide an inkjet recording method capable of recording images with good ink ejection stability and excellent abrasion resistance while circulating ink between the ink storage portion and the recording head over a long period of time. An ink jet recording method in which an aqueous ink is ejected from a recording head and applied to a recording medium to record an image, the ink jet recording method uses an ink jet recording apparatus equipped with an ink circulation flow path for circulating the aqueous ink from an ink storage portion to the recording head, including the ink storage portion for storing the aqueous ink, the recording head of an ink jet system for ejecting the aqueous ink, a cooling portion for cooling the aqueous ink, a heating portion for heating the aqueous ink, and a pump for circulating the aqueous ink.
