Abstract
A liquid ejecting head includes a nozzle, first and second pressure chambers communicating with the nozzle, a first driving element configured to change a pressure in the first pressure chamber, and a second driving element configured to change a pressure in the second pressure chamber. A first flow path length of a flow path from the first pressure chamber to the nozzle is shorter than a second flow path length of a flow path from the second pressure chamber to the nozzle. In a driving method of a liquid ejecting head, at least the first and second driving elements are driven to eject a liquid from the nozzle, and a driving timing of the second driving element is earlier than a driving timing of the first driving element.
