摘要： An object of the present invention is to provide an ink jet print head having plural types of nozzles arranged on the same substrate and through which ink droplets of different sizes are ejected, the ink jet print head exhibiting acceptable ejection performance regardless of the type of the nozzle. Thus, according to the present invention, each of the plural types of nozzles includes a bubbling chamber having an ejection energy generating element allowing an ink droplet to be ejected to a position located opposite an ejection port and an ejection port portion allowing the ejection port and the bubbling chamber to communicate with each other. Ratio of opening area of the ejection port portion at a position where the ejection port portion and the bubbling chamber communicate with each other, to the opening area of the ejection port is higher for the nozzle with a smaller ejection amount.

摘要： A recording head has a channel forming member and an element substrate. A discharge port through which liquid is discharged is formed in the channel forming member. An energy generating element for discharging the liquid is formed in the substrate. A gap forming member is arranged above the channel forming member. A moisture retention liquid retention portion which retains moisture in the vicinity of the discharge port is formed between the gap forming member and the channel forming member so as to be opened toward the discharge port side. Even if the state in which the liquid is not discharged continues, the liquid in the discharge port can be prevented from drying with the recording head having the above configuration.
