发明名称 Liquid ejection head and image forming apparatus
摘要 A liquid ejection head which forms an image, has: a nozzle from which liquid is ejected in a combination ejection direction and which includes a first nozzle region and a second nozzle region demarcated by a partition; a pressure chamber unit which includes a first pressure chamber connected to the first nozzle region and a second pressure chamber connected to the second nozzle region, the first pressure chamber and the second chamber being demarcated by the partition; and a single piezoelectric element which vibrates the first pressure chamber at a first resonance frequency and the second pressure chamber at a second resonance frequency in accordance with an electric field applied to the single piezoelectric element, the first resonance frequency being different from the second resonance frequency.
