ABSTRACT:
In an inkjet printer, an intermediate pulse having a small amplitude is applied in the vicinity of the mid point of the driving cycle of a piezoelectric element, in other words, in the time period from the start of application of a main pulse corresponding to a single printed dot until the start of application of a main pulse corresponding to the next printed dot. The intermediate pulse having such a small amplitude can prevent a wave which results in variations in printed dots in ink in an ink channel from being generated by the main pulse. As a result, an inkjet recording apparatus capable of maintaining picture quality without increasing the load during driving the piezoelectric element can be provided.
