摘要： An ink jet type recording head including nozzle openings, a pressure generating chamber communicating with a common ink chamber via ink supply ports and having a Helmholtz resonant frequency having a period Tc, and a piezoelectric vibrator for expanding and contracting the pressure generating chamber can be driven at a high drive frequency by a method, which comprises a first step of expanding the pressure generating chamber, a second step of maintaining the expanded state, and a third step of contracting the pressure generating chamber placed in the expanded state to discharge ink droplets from the nozzle openings, and in which the duration of the second step is made at most half the period Tc of the Helmholtz resonant frequency to make oscillation of meniscus as small as possible to thereby prevent satellite due to reveral rising of meniscus and generation of ink mist and to shorten a dampening time of meniscus corresponding to the oscillation reduction.
