Abstract
When an ink film between an outer cap and a nozzle face is broken, an ink film formed between an inner cap and the nozzle face is not broken for the following reason. That is, when the ink film between the outer cap and the nozzle face is broken, a negative pressure is not generated on a space formed by the inner cap because the ink film between the inner cap and the nozzle face is formed to be thick and the space communicates with the outside environment by cutouts. Therefore, the ink film formed on the inner cap is not broken at a time when the ink film formed on the outer cap is broken to the inner side with a negative pressure. This makes it possible to suppress splashing droplets from traveling to nozzle rows.
