Inkjet recording head and inkjet recording apparatus

Abstract

In an inkjet recording head having a plurality of ink ejecting ports and a plurality of energy generating elements respectively positioned in confrontation with the ink ejecting ports for generating energy utilized to eject ink from the ink ejecting ports, the plurality of ink ejecting ports and the plurality of energy generating elements being divided into a plurality of blocks, and the ejecting ports and the energy generating elements being timeshapred driven in a sequence of the blocks in a common driving period, the plurality of energy generating elements are disposed in an approximate sraight line, and the respective ink ejecting ports are off-set with respect to the energy generating elements in a projecting relationship in correspondence to the sequence of the timeshapred drive. With this construction, the inkjet recording head can maximize a refill cycle while keeping the linearity of an image even if timeshared drive is executed, whereby the throughput of a printer using the inkjet recording head can be improved.
