Abstract: There are provided a liquid jet head and so on capable of increasing the ejection reliability. A liquid jet head according to an embodiment of the present disclosure includes a jet unit including a plurality of nozzles, a plurality of pressure chambers which is individually communicated with the plurality of nozzles, and which is filled with the liquid, a liquid supply chamber configured to supply the liquid to insides of the pressure chambers, and a liquid recovery chamber configured to recover the liquid from the insides of the pressure chambers, and a drive unit configured to drive the jet unit based on a drive signal to jet the liquid which fills the inside of the pressure chamber from the nozzle. The drive unit drives the jet unit based on a first drive signal as the drive signal when performing a printing operation on a recording target medium so as to achieve ejection strength lower than meniscus breaking strength of breaking a meniscus in the jet unit, and drives the jet unit based on a second drive signal as the drive signal when performing a flushing operation as a non-printing operation of performing dummy ejection of the liquid from the nozzle so as to achieve the ejection strength higher than the meniscus breaking strength.
