A device includes a drive portion for driving a pressure generating element and controlling a state of driving the element. The drive portion includes a first drive section for causing a first current to flow to drive the element, and a second drive section for causing a second current smaller than the first current to flow to drive the element. The state of driving the element includes a first state and a second state. The second drive section causes the second current to flow in a direction in which the element is switched from the first state to the second state at a timing that is faster by a predetermined time determined in advance with respect to a timing at which the first drive section causes the first current to flow for switching the state of driving the element from the first state to the second state. |
