Liquid ejection apparatus and liquid ejection head

A liquid ejection apparatus using a liquid ejection head and ejecting liquid from the liquid ejection head, the liquid ejection apparatus comprising:

• a driving unit configured to drive a heating element;
• and
• a detection unit configured to detect an ejection state of the liquid ejection head based on an output from a temperature detection element provided in the liquid ejection head in a case where the driving unit drives the heating element to eject liquid from an ejection port of the liquid ejection head, wherein
• the liquid ejection head includes, in correspondence to the ejection port:
• a foaming chamber communicating with the ejection port;
• a first heating element for ejecting liquid from the ejection port by providing thermal energy to liquid in the foaming chamber;
• the temperature detection element for detecting temperature in the foaming chamber;
• and
• a second heating element generating thermal energy and arranged closer to the temperature detection element than the first heating element.
