There is disclosed an image recording apparatus including an inkjet printhead and a cap. The inkjet printhead has a plurality of pressure chambers, a common ink chamber that is commonly connected to the pressure chambers to supply ink therefrom to the pressure chambers, and a nozzle surface including a nozzle area and an overlapping area. In the nozzle area, a row of nozzles respectively connected to the pressure chambers are open, and the ink supplied to the pressure chambers is then supplied to the corresponding nozzles to be ejected therefrom. The overlapping area overlaps with the common ink chamber as seen in a direction perpendicular to the nozzle surface. The cap has a close-contact portion, and is brought into contact with, and away from, the nozzle surface, and when in contact with the nozzle surface, the cap air-tightly closes the nozzle surface with the close-contact portion encircling the nozzle area and not contacting the overlapping area.
