Ink jet recording method and ink jet recording apparatus

An ink jet recording apparatus comprising a recording head including:

• a plurality of ejection orifices each configured to eject an ink;
• an ejection element configured to generate energy for ejecting the ink;
• and a first flow path and a second flow path which communicate to each other between each of the plurality of ejection orifices and the ejection element and inside which the ink flows,
• the ink jet recording apparatus further comprising:
• a flow unit, which is separate from the ejection element, configured to flow the ink in the first flow path into the second flow path;
• and
• a mechanism configured to warm the ink in the recording head,
• wherein the recording head is a recording head of a serial type which includes an ejection element substrate including a plurality of ejection orifice arrays each having the plurality of ejection orifices arranged in a predetermined direction and which is scanned in a direction intersecting with an arrangement direction of the ejection orifice arrays,
• wherein the first flow path and the second flow path are arranged in parallel to a scanning direction of the recording head and have the same flow direction of the ink,
• wherein 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, and the first ejection orifice array and the second ejection orifice array are arranged on an upstream side and on a downstream side, respectively, with respect to the flow direction of the ink, and
• wherein a static surface tension γs1 of the first ink and a static surface tension γs2 of the second ink satisfy a relationship of γs1≥γs2.

An ink jet recording method comprising recording an image by ejecting an ink from a recording head including:

• a plurality of ejection orifices each configured to eject the ink;
• an ejection element configured to generate energy for ejecting the ink;
• and a first flow path and a second flow path which communicate to each other between each of the plurality of ejection orifices and the ejection element and inside which the ink flows, the ink jet recording method comprising:
