Abstract:
1. A liquid discharging method of discharging liquid as a liquid droplet from a discharge port by increasing or decreasing a volume of a liquid chamber communicating with the discharge port, the method comprising: separating a substantially spherical liquid portion connected to a front end of a portion of the liquid extending in a column shape from the discharge port, from the front end, to form the liquid droplet, the portion of the liquid extending in the column shape being gradually thickened toward the discharge port immediately after the separation; and maintaining the portion of the liquid extending in the column shape so as not to be separated at any position of the portion of the liquid extending in the column shape; and retracting the portion of the liquid extending in the column shape into the discharge port by protruding a protruding portion of the liquid to an outside from the discharge port.
