Recording head and recording apparatus using the same
 Upon executing printing by latching an input digital image signal temporarily stored in a shift register (502) by a latch circuit (501), and energizing and driving a heater (401) using a power transistor (410) using an nMOSFET on the basis of the latched image signal, a voltage converter (111) boosts a voltage representing the ON state of the latched digital signal, and applies the boosted voltage to the power transistor (410).
