Claim Text:
1. A method of manufacturing gel particles adapted to apply a voltage to a liquid ejection head to eject a liquid including a polymeric material toward an ejection target liquid to thereby manufacture the gel particles, the method comprising: raising the voltage from a first voltage to a second voltage at a first gradient, wherein the first voltage is an intermediate voltage that is between a voltage maximum and a voltage minimum; raising the voltage from the second voltage to a third voltage, without holding the voltage at the second voltage, at a second gradient steeper than the first gradient at which the voltage is raised from the first voltage to the second voltage, and then holding the voltage at the third voltage, wherein the third voltage is the voltage maximum; dropping the voltage from the third voltage to a fourth voltage, and then holding the voltage at the fourth voltage; raising the voltage from the fourth voltage to a fifth voltage at a third gradient, and then holding the voltage at the fifth voltage; dropping the voltage from the fifth voltage to a sixth voltage, and then holding the voltage at the sixth voltage, wherein the sixth voltage is the voltage minimum; and raising the voltage from the sixth voltage to a seventh voltage, wherein the third gradient at which the voltage is raised from the fourth voltage to the fifth voltage is gentler than the second gradient at which the voltage is raised from the second voltage to the third voltage, wherein the second voltage is one of equal to or higher than 50% of the third voltage.
