PROBLEM TO BE SOLVED: To prevent the stop of movement caused by an excessive heat-generation of a drive-signal formation section while making the speed of processing higher. SOLUTION: The liquid delivery equipment is provided with a first drive-signal formation section 70A and a second drive-signal formation section 70B for forming a plurality of a first drive-signal COM_A and a second drive-signal COM_B whose power consumption are different, respectively, a piezoelectric element 417 for performing a movement to deliver a liquid based on the first drive-signal COM_A and second drive-signal COM_B and a controller (printer side controller 60) for making the first drive-signal COM_A formed in the drive-signal formation section at the side of low temperature while making the first drive-signal COM_A in the drive-signal formation section at the side of high temperature based on the temperature of both the first and second drive-signal formation sections 70A, 70B.
