An inkjet recording apparatus and an inkjet recording method which enable changing a droplet amount without changing a droplet speed of an ink discharged from the same nozzle, and including an inkjet head which expands and contracts a capacity of a pressure chamber by applying a driving signal to an actuator and a driving circuit which applies the driving signal to the actuator, the driving signal including a first expansion pulse which starts from a reference potential and expands the capacity of the pressure chamber, a first contraction pulse which contracts the capacity of the pressure chamber to discharge the ink from the nozzle, a second expansion pulse which expands the capacity of the pressure chamber, and a second contraction pulse which contracts the capacity of the pressure chamber and returns to the reference potential in the mentioned order, the driving circuit being configured to enable discharging different droplet amounts of the ink from the same nozzle by changing a potential difference between a start edge and an end edge of the first contraction pulse.
