Abstract:
A liquid ejecting head includes a liquid channel having a pressure generating chamber communicated with a nozzle opening that ejects liquid, and a first liquid chamber installed at one end of the pressure generating chamber to communicate a plurality of pressure generating chambers; a pressure generating unit for changing pressure in the pressure generating chamber so that liquid is discharged from the nozzle opening; a heating unit for heating liquid in the liquid channel at an upstream of the pressure generating chamber; a second liquid chamber installed at the other end of the pressure generating chamber; and a circulating channel formed among a pressure generating chamber group having at least one pressure generating chamber to connect the first liquid chamber and the second liquid chamber.
