Abstract: Power consumed by a resistor connected between a first power supply and a drive control circuit is controlled by a power driving circuit connected to a second power supply. When the value of current that flows into the resistor fluctuates, the value of current output from power driving circuit to a control terminal of the drive control circuit is controlled in such a manner that power consumed is the same as that when the resistance value of the resistor is a set value. As a result, the value of power consumed by the resistor is rendered substantially constant without being influenced by a variation in the resistance value of the driven resistor or by the power supply voltage. If such a drive circuit is used in driving the printhead of a printing apparatus, stabilized drive can be achieved with the minimum margin, power consumption can be suppressed and the lifetime of the printhead can be prolonged.
