An inkjet recording apparatus for recording an image on a recording medium, including a recording head, a drive circuit and a control device. The head includes an ink passage, a nozzle communicated with the passage, an actuator applying energy to ink in the passage to eject a droplet of the ink from the nozzle onto the medium. The drive circuit outputs a signal for driving the actuator to eject the ink droplet such that at least three ink droplets are ejected for printing one dot. The control device controls operation of the circuit and includes a high-temperature control portion and a low-temperature control portion. The former portion operates, in a first case where an environmental temperature is higher than a threshold, to control the circuit to output a first kind of the signal according to which a dot is formed by a number of ink droplets ejected in series and landing on the medium sequentially in the order of ejection. The latter portion operates, in a second case where the environmental temperature is not higher than the threshold, to control the circuit to output a second kind of the signal according to which a dot is formed by the same number of ink droplets as in the first case. A total ink volume of the droplets ejected according to the second kind signal is smaller than that according to the first kind signal.
