This invention provides a method of and apparatus for emitting a droplet from an orifice by generating a bubble in a small liquid chamber in response to a droplet generating instruction. The method and apparatus are particularly characterized having gradual contraction of the bubble to prevent excessive recession of the orifice in the liquid chamber which recession would hinder subsequent droplet generation.

For achieving the above-mentioned functions the droplet generating apparatus, or the droplet emitting head, is provided with a structure which allows effective generation and annihilation of the bubble. The present invention also provides a novel apparatus having emission heads in a staggered block arrangement for improving alignment density of the devices and elements and time-division drive circuitry.
