An image-recording apparatus includes a cartridge including a first storage chamber, a tank including a second storage chamber, a recording portion for ejecting liquid stored in the second storage chamber, a detected portion, and a detector. The first and second storage chambers can communicate with an atmosphere. The tank includes a liquid inlet port and a liquid outlet port positioned lower than the liquid inlet port. Liquid in the first storage chamber is supplied to the second storage chamber through the liquid inlet port, and from the second storage chamber to the recording portion through the liquid outlet port. The detected portion can change in state when a level of the liquid stored in the second storage chamber becomes equal to a vertical position of the liquid inlet port. The detector is configured to detect the change in state of the detected portion.
