Abstract:
A contraction portion of a vibration pulse includes a first contraction element which occurs subsequent to an expansion portion, a contraction maintaining element which follows the first contraction element, and a second contraction element which follows the contraction maintaining element, and when a time from a start point time of the expansion portion to an end point time of the expansion portion is set as t1, a time from the end point time of the expansion portion to a start point time of the contraction portion is set as t2, and a natural vibration period of ink in an ink flow path including a pressure chamber is set as Tc, the start point time (t1+t2) of the contraction portion is set to be in the range of any one of the following expressions (1) and (2). (t1+t2) t1/2+5Tc/8 (2)
