An injector driver and a drive method therefor wherein a reference current signal is generated that is synchronized to an injector valve signal for causing the injector to inject and that has a current increasing tendency substantially equivalent to an injector current waveform for the case in which a low voltage is applied to the injector, a current that flows in the injector is detected as a detected current signal, and the electrical powering of the injector is controlled by comparing the reference current signal with the detected current signal.
