Patent ID: 7384112

Claim:
An inkjet recording apparatus for recording an image on a recording medium, comprising: a recording head including: an ink passage with ink therein; a nozzle in communication with the ink passage; an actuator which applies energy to the ink in the ink passage to eject a droplet of the ink from the nozzle onto the recording medium; a drive circuit which outputs a drive signal for driving the actuator to eject the droplet of the ink, such that at least three droplets of the ink are ejected for printing one dot on the recording medium; and a control device which controls operation of the drive circuit, and includes: a high-temperature control portion which operates, in a first case where a temperature of an environment in which the apparatus is situated is higher than a predetermined threshold, to control the drive circuit to output a first kind of the drive signal according to which a dot is formed by a number of droplets of the ink, which are ejected in series and land on the recording medium sequentially in the order in which the droplets have been ejected; and a low-temperature control portion which operates, in a second case where the temperature of the environment is not higher than the predetermined threshold, to control the drive circuit to output a second kind of the drive signal according to which a dot is formed by the same number of droplets of the ink as in the first case, a total ink volume of the droplets ejected according to the second kind of the drive signal being smaller than that according to the first kind of the drive signal.
