ABSTRACT:
A liquid ejection head includes a nozzle plate having a nozzle that ejects liquid drops, an actuator that deforms a portion of the nozzle plate surrounding the nozzle with heat, and a flow path member opposing the nozzle plate, which forms a flow path for guiding liquid to the nozzle. A fluidity resistance path is provided in the flow path between a nozzle plate portion surrounding the nozzle and a portion of the flow path member opposing the nozzle plate portion. A fluidity resistance of the fluidity resistance path is changed by deforming the nozzle plate portion.
