Abstract
A multi-nozzle ink jet recording apparatus having a plurality of nozzle apertures arranged in parallel for generating ink droplets. Information signals as applied to respective electrical energy-mechanical energy converting elements associated with independent ink chambers in communication with the respective nozzle apertures to selectively generate from the nozzle apertures ink droplets necessary for recording in response to the information signals. The electrical signals applied to the converting elements associated with adjoining independent ink chambers are rendered mutually out of phase to thereby prevent generation of surplus ink due to interference between the adjoining independent ink chambers.
