Abstract

The invention aims to provide a liquid ejecting head and a liquid ejecting apparatus; the liquid ejecting head can inhibit bad conditions in high load spraying and improve bubble discharging performance. A storage device comprises a first storage device in which an ink guiding-in port (12) is arranged in a position close to the center on the jet nozzles arrangement direction relative to the storage device (16), and a second storage device in which an ink guiding-in port is arranged in a position close to the end on the jet nozzles arrangement direction relative to the first storage device. In a plurality of kinds of inks sprayed from the recording head, the inks having higher pressure at the ink guiding-in port are guided into the first storage device when liquid is ejected from a certain number of jet nozzles in a certain period.

Description

technical field

[0001] The present invention relates to, for example, a liquid ejection head such as an ink jet recording head and a liquid ejection device provided with the liquid ejection head, and particularly relates to a liquid ejection head and a liquid ejection device capable of suppressing ejection failure under high load and improving bubble discharge performance. device. Background technique

[0002] The liquid ejection device includes a liquid ejection head capable of ejecting a liquid as a liquid, and ejects various liquids from the liquid ejection head. As a representative of such a liquid ejecting device, for example, an ink jet recording device (printer) that includes an ink jet recording head (hereinafter referred to as a recording head) and ejects liquid ink from the recording head to perform recording, etc. image recording device. In addition, in recent years, it has been applied not only to the image recording apparatus, but also to various manufacturing...
