1. A recording method comprising:
discharging a water-based recording ink from a head onto a recording medium conveyed in a conveying direction and heating the recording medium or the water-based recording ink adhered to the recording medium with a heater to record a first image on the recording medium;
reading the first image to determine whether the first image is correctly recorded; and
when the first image is determined as not being correctly recorded, conveying the recording medium in a reverse direction relative to the conveying direction, and recording a second image over the first image,
wherein
the water-based recording ink comprises: a resin-dispersed pigment; a fine resin particle; a water-soluble organic solvent; and water,
the water-soluble organic solvent comprises at least one selected from the group consisting of a glycol ether and a diol compound having six to eight carbon atoms and two hydroxyl groups, at least one of the two hydroxyl groups not being bonded to a terminal of a carbon chain of the diol compound, and
a content of substances having a vapor pressure of 0.03 hPa or less at 20° C. in the water-based recording ink relative to a total mass of the water-based recording ink is 10 mass % or less, and a surface tension of the water-based recording ink is 30 mN/m or less,
and wherein a cumulative heating amount received by the recording medium from the heater at a position opposing the heater per unit area of the recording medium is within a range of 0.05 J/cm2 or more and 2.50 J/cm2 or less.
