Abstract
An ink jet recording apparatus includes an ink jet head, a body frame, and a cover plate. The ink jet head has a plurality of nozzles that eject ink onto a recording medium, a plurality of pressure chambers provided in association with the nozzles, and a plurality of pressure generating portions that apply pressure to the pressure chambers so as to allow the ink to be ejected from the nozzles. The body frame communicates with an ink supply source and the ink jet head so as to supply the ink to the ink jet head. The cover plate has at least one window in a shape so as to enclose the nozzles. The cover plate is fixed to cover the ink jet head and fixed to the body frame. The ink jet recording apparatus further includes an inlet that communicates with an internal space formed between the body frame and the cover plate and an at least one outlet that communicates with the internal space. A filling material is supplied from the inlet and ejected to the at least one outlet.
