Abstract
A liquid discharge apparatus including a liquid discharge head having a substrate, plural pressure chambers two-dimensionally provided on one surface of the substrate, a discharge port, a pressure generating unit to discharge liquid through the discharge port and a flow path connected to the pressure chamber which are provided correspondingly to each pressure chamber, a common liquid chamber provided on the other surface of the substrate, and plural supply paths provided between adjacent pressure chambers and connected to the common liquid chamber; a moving unit to relatively move the liquid discharge head and a recording object; and a driving unit to drive the pressure generating unit. Flow paths respectively corresponding to the pressure chambers adjacent to the supply paths are connected to the supply paths. The driving unit outputs drive signals to the pressure generating units respectively corresponding to the pressure chambers connected to the supply paths at different timings.
