Abstract:
An object of the present invention is to provide an ink jet recording method capable of exhibiting excellent ejection stability of ink even after recording an image over a long period of time, while recording an image having a high optical density. The ink jet recording method is a method of recording an image by ejecting ink from a recording head including an ejection orifice ejecting the ink, an ejection element generating energy for ejecting the ink, and first and second flow paths which 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 in the first flow path to the second flow path separately from the ejection step, wherein the ink is aqueous ink containing a self-dispersible pigment in which an anionic group is bonded to a particle surface of the pigment directly or through another atomic group, and a nonionic surfactant, the self-dispersible pigment having a surface charge amount of 0.40 mmol/g or less.

Claim (Index 7):
An ink jet recording apparatus comprising:\n a recording head including an ejection orifice ejecting the ink, an ejection element generating energy for ejecting the ink, and first and second flow paths which communicate between the ejection orifice and the ejection element and in which the ink flows; and a flowing unit flowing the ink in the first flow path to the second flow path separately from the ejection element, wherein the ink is aqueous ink containing a self-dispersible pigment in which an anionic group is bonded to a particle surface of the pigment directly or through another atomic group, and a nonionic surfactant, the self-dispersible pigment having a surface charge amount of 0.40 mmol/g or less.
