Abstract

A liquid ejection head (1) includes: an ejection module (11) which includes an ejection driver element (MD1) and an ejection heater (RhA) capable of being electrically connected to the ejection driver element (MD1); a circulation module (12) which includes a circulation driver element (MD2) and a circulation heater (RhB) capable of being electrically connected to the circulation driver element (MD2); and a controller (202) which controls each of the ejection driver element (MD1) and the circulation driver element (MD2) into any one of a conduction state and a non-conduction state. The controller (202) makes an ejection drive frequency utilized to drive the ejection driver element (MD1) and a circulation drive frequency utilized to drive the circulation driver element (MD2) different from each other.
