The present application is in at least one aspect directed to solving a problem of providing an inkjet recording device and an inkjet head driving method, in which instantaneous power consumption of a plurality of drive waveform generation circuits can be reduced while not requiring correction of an ink landing position without a complex structure. The problem is solved by dividing a plurality of pressure generating elements into first to n-th sets (n is an integer of 2 or more), and applying drive pulses to the pressure generating elements in the respective sets per every pixel period. The drive pulse combines any one of n time sharing drive waveforms (time sharing drive) with a common drive waveform (COM) as a rendering waveform, and the n time sharing drive waves are obtained by delaying a part of the rendering waveform by a time different from each other and have application timing deviated from each other.
