Liquid ejecting head, imaging forming apparatus, device for ejecting a liquid drop, and recording method
Abstract:
A liquid ejecting head comprising a nozzle configured to eject a liquid drop of recording liquid, a liquid chamber communicating to the nozzle, and an energy generating device configured to generate energy for pressurizing recording liquid in the liquid chamber is provided, wherein a flow channel forming member configured to form a flow channel for the recording liquid is made of a metal material containing nickel and a peak intensity for a (200) face of nickel is higher than a peak intensity for a (111) face of nickel which intensities are measured by means of X-ray diffraction analysis, or a flow channel forming member configured to form a flow channel for the recording liquid is made of a metal material containing nickel and thallium.
