Abstract

A method for discharging fluid, includes while keeping two members relatively moving to each other along a gap direction of a gap formed by two opposing surfaces of the two members, feeding fluid from a fluid supply device to the gap, and intermittently discharging the fluid by utilizing a pressure change made by changing the gap, and controlling a fluid discharge amount per dot depending on pressure and flow rate characteristics of the fluid supply device.
