LIQUID JET RECORDING PROCESS AND APPARATUS THEREFOR

摘要

TITLE OF THE INVENTION Liquid Jet Recording Process and Apparatus Therefor Liquid droplets are formed by a thermally engendered instantaneous state change of a liquid in a thermal chamber, said droplets being deposited onto a recording member to achieve recording. The thermal chamber is formed in a recording head so that the repeated formation and contraction of bubbles in ink supplied to the chamber ejects a stream of ink droplets towards the recording member as required. The invention provides a method and apparatus for ink jet recording which combines a simple, compact head structure with the advantage of providing ink droplets only on demand.
