Patent ID: 8668321

Claim:
An ink jet recording method comprising: an image formation step of forming an image on a recording medium having an ink-receiving layer by ejecting an ink from an ink jet recording head; and a humidification step of humidifying a gap between the recording head and the recording medium, wherein in the image formation step, an ink containing a dye represented by general formula (I) and a water-soluble organic compound having an inorganic-organic balance value of 1.4 or more to 2.7 or less is used: wherein in general formula (I), A, B, C, and D each independently represent a six-membered ring having aromaticity, and at least one of A, B, C, and D represents a pyridine ring or a pyrazine ring; M's each independently represent a hydrogen atom, an alkali metal, ammonium, or organic ammonium; E represents an alkylene group; X represents a sulfo-substituted anilino group, a carboxy-substituted anilino group, or a phosphono-substituted anilino group, and the substituted anilino group may further contain one to four substituents of at least one type of substituent selected from the group consisting of a sulfonic acid group, a carboxy group, a phosphono group, a sulfamoyl group, a carbamoyl group, a hydroxy group, an alkoxy group, an amino group, an alkylamino group, a dialkylamino group, an arylamino group, a diarylamino group, an acetylamino group, an ureido group, an alkyl group, a nitro group, a cyano group, a halogen atom, an alkylsulfonyl group, and an alkylthio group; Y represents a hydroxy group or an amino group; and a, b, and c satisfy 0≦a≦2.0, 0≦b≦3.0, and 0.1≦c≦3.0, provided that a+b+c=1.0 to 4.0, wherein the humidification step is performed by supplying humidified air into the gap between the recording head and the recording medium, and wherein the gap between the recording head and the recording medium is filled with an atmosphere having a temperature of 35° C. or lower and an absolute humidity of 0.013 kg/kgDA or higher.
