Abstract:
1. A method for ejecting liquid droplets by use of a liquid droplet ejection apparatus, said liquid droplet ejection apparatus comprising a pressurizing chamber which has an ejection opening and which is filled with liquid whose viscosity varies with the lapse of time, and pressurizing means for pressurizing said liquid within said pressurizing chamber, said liquid droplet ejection apparatus configured to eject said liquid in the form of substantially a single minute liquid droplet from said ejection opening through a single pressurizing operation by said pressurizing means, characterized in that a plurality of minute liquid droplets are ejected through intermittently iterating said single pressurizing operation by said pressurizing means, and a rate of pressurization by said pressurizing operation is varied depending on intervals between said pressurizing operations iterated.
