Liquid ejecting method
A liquid ejecting method includes ejecting droplets of an oil-based ink containing an oil-based medium onto a recording medium by using an ink jet head having a plurality of nozzles under the conditions satisfying relationships (1): f×D≧4800; and relationship (2): 5≦ρVd/η≦30. In the relationships (1) and (2), D represents the nozzle pitch in dpi of the ink jet head, f represents the maximum ejection frequency in kHz, V represents the velocity in m/s of droplets ejected from the ink jet head, d represents the diameter in μm of the droplets of the oil-based ink, ρ represents the density in g/cm3 of the oil-based ink, and η represents the viscosity in mPa·s of the oil-based ink.
