An image recording apparatus includes a recording head and a capping unit which seals a nozzle forming face of the recording head and sucks the ink from the nozzles. The capping unit includes a cap member having a plurality of housing recesses partitioned from each other for ink suction from a corresponding one of a plurality of groups of the nozzles, and cap chips housed in the respective housing recesses. The cap member includes discharge ports discharging the ink sucked into the respective housing recesses, a peripheral rib positioned at an outer peripheral portion enclosing all of the housing recesses, and a partitioning rib defining the housing recesses, two end portions of the partitioning rib being connected to the peripheral rib. The cap chips include regulating portions which abut against side faces of the partitioning rib to suppress deformation of the partitioning rib in a direction crossing the side faces.
