Abstract

A liquid jet recording head includes liquid discharge ports, pressure chambers, and a substrate which has the discharge energy generating element, a liquid chamber for storing a liquid supplied to the pressure chamber, a pair of paths which are separated from the liquid chamber, and a liquid supply port communicating with the liquid chamber. A liquid inlet port communicating with one path of the pair of paths and a liquid outlet port communicating with the other path of the pair of paths are opened on one surface of the substrate. A liquid flow path for discharging the liquid from the liquid chamber to the pressure chamber via the liquid supply port, and a liquid flow path for circulating the liquid from the one path to each pressure chamber via the liquid inlet port, and further from each pressure chamber to the other path via the liquid outlet port are provided.

Description

technical field [0001] The present invention relates to a liquid ejection recording head and a liquid supply method used in an inkjet recording apparatus. Background technique [0002] A recording head in an inkjet recording device is configured to discharge ink droplets (recording liquid droplets) from discharge ports by changing the ink pressure in a pressure chamber provided on the recording head, and to discharge ink droplets to the recording surface by making the discharged ink adhere to the recording head. to record on the medium. [0003] However, in the inkjet recording method in which ink droplets are ejected according to the above-mentioned principle, when air bubbles enter the pressure chamber, the ink pressure changes undesirably, and the printing operation may become unstable. Therefore, when air bubbles enter the recording head or are generated in the recording head, these air bubbles need to be removed. [0004] When the recording head is in a state without ...
