ABSTRACT:
An ink jet head having a buffer chamber which absorbs any back-pressure wave generated as a result of generation of back wave, thereby preventing reduction of refilling with ink. Exothermic elements provided in buffer chambers formed in a common ink chamber generate bubbles so that bubbles are always maintained in the buffer chambers so as to ensure stable recording.
