Claim 17:
18. A water-based ink for recording comprising:
a resin-dispersed pigment;
resin fine particles of which glass transition temperature is not less than 33° C.;
an organic solvent including a specific organic solvent of which saturation vapor pressure at 20° C. is not less than 0.03 hPa; and
water,
wherein the water-based ink for recording discharged from a printing head is fixed to a recording medium in a state that the recording medium is heated by a heater so that the water-based ink for recording satisfies the following condition (I):, 6
          ≤
          
            
              (
              
                β
                /
                α
              
              )
            
            ×
            1000
          
          ≤
          31
        
        ,
      
    
    
      
        Condition
        ⁢
        
          
        
        ⁢
        
          (
          I
          )
        
      
    
  

in the condition (I),
α (° C.) being the glass transition temperature of the resin fine particles, and
β (J/cm2) being an irradiation energy, radiated from the heater, per unit area of the recording medium.
