Patent ID: 8047637

Claim:
An image forming apparatus which forms an image on a recording medium, comprising: a liquid ejecting head which ejects recording liquid on the recording medium for forming the image on the recording medium, wherein the liquid ejecting head includes a nozzle that ejects liquid; a liquid chamber connected to the nozzle; a vibration plate of which at least one wall of the liquid chamber is formed; and a piezoelectric actuator that deforms the vibration plate, wherein a piezoelectric actuator including: a base member; and three or more piezoelectric element members in which a plurality of piezoelectric elements are formed by slits, wherein the three or more piezoelectric element members are arrayed in a line on the base member and in a same direction as the plurality of piezoelectric elements are arrayed, the three or more piezoelectric element members are arrayed with a gap between two adjacent piezoelectric element members, and an index is formed on the base member so that the three or more piezoelectric element members are arrayed with the gap between two adjacent piezoelectric element members.
