PROBLEM TO BE SOLVED: To provide an ink jet recorder in which each recording block can be driven optimally using one drive signal generating circuit. SOLUTION: A drive signal generating circuit generates a drive signal COM comprising a series of drive pulses DP1, DP3 having waveform optimized for black block, and drive pulses DP2, DP4 having waveform optimized for color block. A shift register, a latch circuit, a decoder, a level shifter and a switch circuit select a drive pulse appropriately from the drive signal COM and deliver the selected drive pulse to the piezoelectric oscillator in a corresponding recording lock. |
