To provide a droplet discharge head and a droplet ejector which can discharge a droplet at a low cost.
A main-scan direction shift register 101 shifts one pixel of data to a main-scan direction at a time in synchronizing with a data transfer clock. The 1st latch circuit 103 latches the pixel data for one line fed from the main-scan direction shift register 101 in synchronizing with a line synchronizing signal and feeds the latched pixel data to a sub-scan direction shift register 105 installed for every sub-scan line, respectively. Each sub-scan direction shift register 105 is configured so that the pixel data input may be output after making it delayed according to the distance from the main-scan direction shift register 101 up to each nozzle position in each sub-scan direction. The sub-scan direction shift register 105 actuates a piezoelectric element 60 by transmitting two pixels of the pixel data at a time to the sub-scan direction in synchronizing with a printing timing clock and a sub-scan clock.
