    摘要： An image recording apparatus includes: a liquid ejection cartridge unit that ejects ink droplets and includes a liquid chamber that stores liquid, and a first and a second electrode pins inserted in the liquid chamber; an application portion that applies a voltage between the first and the second electrode pins; and a detection portion that includes a detection resistance to which a voltage is applied by the application portion and detects a voltage value or a current value. When the application portion applies a voltage, the detection portion detects the voltage value or the current value so that the amount of liquid remaining in the liquid chamber is detected. At least one of the determination threshold value of the amount of the liquid in the liquid chamber, the applied voltage value, or the detection resistance value is set at intervals based on the cumulative application time of the voltage.

    摘要： A printing element includes a substrate, an intermediate layer, and a channel forming member layered in this order. The substrate has a common liquid chamber. The channel forming member has a second surface that is a surface facing the substrate via the intermediate layer, and a first surface that is an opposite surface to the second surface. The first surface is formed with a plurality of ejection ports that eject liquid from the common liquid chamber. The second surface is formed with a plurality of channels that allow each of the plurality of ejection ports and the common liquid chamber to communicate with each other, and a plurality of substantially parallel beam structures, the plurality of beam structures forming a slit portion therebetween.
