Abstract
Provided is an ink jet recording method in which a high-quality image having a ruled line shift suppressed can be recorded with a circulation serial head and in which a change in color tone of an image due to ink color mixing can be suppressed even at the time of long-term use. The ink jet recording method includes recording an image by ejecting an ink from a recording head including: a plurality of ejection orifices. The plurality of ejection orifice arrays includes a first ejection orifice array configured to eject a first ink and a second ejection orifice array configured to eject a second ink on an upstream side and on a downstream side, respectively, with respect to a flow direction of the ink. A static surface tension γsof the first ink and a static surface tension γsof the second ink satisfy a relationship of γs≥γs.
