Abstract:
An object of the present invention is to provide an ink jet recording method capable of recording a high-quality image in which occurrence of unevenness is decreased. 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 pigment and a specific compound having an ethylene oxide group.

Claim (Index 11):
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 pigment and a compound having an ethylene oxide group, and the compound having an ethylene oxide group is at least one selected from the group consisting of the following compound A, compound B and compound C: compound A: polyhydric alcohol derivative in which X mole(s) of ethylene oxide group(s) and Y mole(s) of propylene oxide group(s) are added to a polyhydric alcohol having three or more hydroxy groups and a proportion of {X/(X +Y)}\u00d7100(%) is 5% or more to 45% or less compound B: polyethylene glycol having a number average molecular weight of 600 or more to 4,000 or less (provided, a content (% by mass) of the compound B in the ink is 0.10 times or more as a mass ratio with respect to a content (% by mass) of the pigment), and compound C: polyoxyethylene alkyl ether having a hydrocarbon group in which the number of carbon atoms is 12 or more.
