ABSTRACT:
A multihead liquid emission recording apparatus comprises a plurality of liquid emission nozzles; a plurality of electromechanical conversion elements each provided for each of said plurality of liquid emission nozzles for jetting a recording liquid particle from each nozzle; and drive circuit means for driving each of said electromagnetic conversion elements by a voltage signal corresponding to its recording signal; wherein the change range of said drive signal for driving each of said electromagnetic conversion element is set such that the variation ranges of dot diameters on a recording medium formed by said recording liquid particle jetted out of each of said liquid emission nozzles become substantially the same.
