Abstract
An ink jet recording method capable of recording a high-quality image in which occurrence of fine unevenness is decreased. The ink jet recording method includes recording an image by ejecting ink from a recording head including an ejection orifice for ejecting the ink, an ejection element generating energy for ejecting the ink, and first and second flow paths that communicate between the ejection orifice and the ejection element and in which the ink flows. The ink jet recording method includes an ejection step of ejecting the ink from the ejection orifice, and a flow step of flowing the ink from the first flow path to the second flow path separately from the ejection step. The ink is an aqueous ink having a dynamic surface tension of 35 mN/m or more to 48 mN/m or less at 10 milliseconds.
