<p>A liquid discharge recording method utilizing two electrothermal transducing members (101,102) to be driven independently provided in a liquid path (103) communicating with a discharge opening at different distances OH from the discharge opening, and adapted to discharge liquid by bubble generation caused by heat generation in the electrothermal transducing members, in which an electrothermal transducing member positioned farther from the discharge opening is placed within an area where a ratio v/Vd of a discharge speed v to a discharge amount Vd of the liquid discharged by heating with the electrothermal transducing member remains substantially constant with respect to the distance OH, while the other electrothermal transducing member positioned closer to the discharge opening is placed in an area closer to the discharge opening than the above mentioned range; and the bubble generation by the electrothermal transducing member positioned farther from the discharge opening is delayed by a predetermined time from the bubble generation by the electrothermal transducing member positioned closer to the discharge opening, the predetermined time being variable to vary the discharge amount of the liquid.</p> |
