Abstract
An ink-jet image recording method is disclosed. In the method an aqueous ink containing a colored particles comprising a colorant and a resin is employed, and following Formula 1 is satisfied; 15≦w≦150 Formula 1 wherein, w is a parameter expressed by following Formula 2; w=[(dm+ds)/{(NV×vd)/r3}]×10,000 Formula 2 wherein, ds is a recording density in dpi in a moving direction of the recording medium and dm is a recording density in dpi in a direction perpendicular to the moving direction of the recording medium, NV is the colored particle content in the ink in weight percent, vd is a volume average radius in meter of the colored particles and r is radius in meter of the ink droplet.
