Abstract
It is an object of the present invention to provide an image recording method and apparatus for performing stable image recording with a minimum power consumption. An AND gate performs an AND operation of a clock signal and a printing signal of binary logic in units of pixels, and a transistor is driven. At the driving timing, an induced electromotive force is generated in a choke coil having one end connected to a power supply line. A capacitor is charged with a forward current through a diode. On the other hand, the signal is shift-input to a shift register and latched by a latch circuit in synchronism with a signal. An output from the latch circuit is supplied to a gate circuit in synchronism with a signal to drive a transistor. A current from the capacitor is input to the transistor to heat a heater.
