Abstract
An ink jet head having a plurality of electrothermal transducer elements in one liquid passage is arranged so that the ratio of the areas of two of the plurality of electrothermal transducer elements is smaller than the ratio of the amounts of ink ejected by the two electrothermal transducer elements, thereby stably obtaining the desired amounts of ejected ink and achieving a high gradational effect at a high energy efficiency.
