| 发明名称 | Inkjet recording apparatus and inkjet recording method | ||
| 摘要 | An inkjet recording apparatus includes an inkjet recording head including a first nozzle having a discharge port, a pressure chamber having therein an element, and a flow path, a second nozzle having a flow resistance lower than that of the first nozzle, and a supply port configured to, after discharge of an ink droplet from at least one of the first nozzle and the second nozzle, supply ink to the nozzle, a storage unit storing a rank value depending on a size of a portion relating to the flow resistance, a reading unit configured to read the rank value, a determination unit configured to determine a number of discharges per unit time of each nozzle based on the rank value read by the reading unit, and a control unit configured to control each nozzle to discharge the ink droplet based on the number of discharges determined by the determination unit. | ||

| 主权项 | 1. An inkjet recording apparatus comprising: an inkjet recording head including a first nozzle having a discharge port configured to discharge liquid, a pressure chamber having therein an element configured to generate energy for discharging the liquid, and a flow path communicating with the pressure chamber, a second nozzle adjacent the first nozzle having a flow resistance less than a flow resistance of the first nozzle, and a supply port configured to, after discharge of an ink droplet from at least one of the first nozzle and the second nozzle, supply ink to the nozzle that has discharged the ink droplet; a storage unit storing a rank value of the inkjet recording head ranked in advance depending on a size of a portion relating to the flow resistance; a reading unit configured to read the rank value from the storage unit; a determination unit configured to determine a number of discharges per unit time of each nozzle based on the rank value read by the reading unit; and a control unit configured to control each nozzle to discharge the ink droplet based on the number of discharges determined by the determination unit. | ||
