1. An inkjet recording device comprising:
an inkjet discharge head including a nozzle through which ink is discharged, a pressure chamber that communicates to the nozzle, and a pressure generator that generates a pressure change in ink in the pressure chamber according to application of a drive signal to cause ink to be discharged from the nozzle;
a driver that is disposed outside the ink discharge head and that is provided with a drive circuit that outputs the drive signal; and
a wire that electrically connects the driver with the ink discharge head and through which the drive signal output from the drive circuit and applied to the pressure generator,
wherein the driver includes a resistance element provided in a transmission path of the drive signal between the drive circuit and the wire,
wherein a magnitude of a resistance value of the resistance element corresponds to a length of the wire,
wherein the resistance element is provided in a state in which the resistance value is changeable,
wherein the inkjet recording device further comprises:
a resistance value controller that changes the resistance value of the resistance element; and
a temperature detector that detects a temperature corresponding to the temperature in the ink discharge head, and
wherein the resistance value controller adjusts the resistance value of the resistance element based on the temperature detected by the temperature detector.
