Recording head and recording apparatus using the same

摘要

A recording head or the like having a voltage generating circuit which does not depend on a voltage fluctuation of a heater driving power source (first power source) is provided. The recording head has: a plurality of heaters connected to a power line VH as a heater driving power source; a power transistor as a switching element for independently driving each heater by supplying a current thereto; and a voltage generating circuit for supplying a voltage for a control signal for controlling the power transistor. The voltage generating circuit has a resistor R 1 connected to a grounding potential and an n-type MOS transistor T 1 in which a reference voltage V 1 which is generated by supplying a constant current from a constant current source I 0 to the resistor R 1 is inputted to a gate.
