Abstract
An inkjet cartridge having a plurality of ink reservoirs and a plurality of nozzle rows without variations in lengths of ink flow paths communicating the ink reservoirs with the nozzle rows. An inkjet cartridge includes a tank part having a plurality of ink reservoirs and a head part having nozzle rows, each nozzle row having a plurality of nozzles from which ink supplied from the tank part is ejected. Each of ink supply ports provided in each of the ink reservoirs is communicated with a predetermined nozzle row via an ink flow path, and the plurality of ink reservoirs are formed by dividing an internal space of the tank part into equal parts on a plane perpendicular to an ink ejection direction while lengths of a plurality of ink flow paths are the same.
