Claim:
1. A recording method comprising: ejecting aqueous ink to a surface of a recording medium by an ejection head, the aqueous ink containing a colorant, polymer particles having a glass-transition temperature Tg of 35° C. to 65° C., and a solvent containing water and an aqueous organic solvent, the aqueous ink having a viscosity ratio (V35/Vi) that is lower than 2.0, V35 being a viscosity that is obtained when the aqueous ink is heated at 35° C. for 30 minutes and Vi being an initial viscosity of the aqueous ink obtained at a temperature of 23° C. without heating, the aqueous ink having a viscosity ratio (V65/Vi) that is 8.0 to 20.0, V65 being a viscosity that is obtained when the aqueous ink is heated at 65° C. for 30 minutes and Vi being the initial viscosity of the aqueous ink obtained at a temperature of 23° C. without heating; and drying the aqueous ink ejected to the surface of the recording medium by the ejection head, wherein a head temperature Th of the ejection head, the glass-transition temperature Tg of the polymer particles, and a drying temperature Td satisfy an expression: Th<Tg<Td.
