The toner particle has a core that contains resin A and a shell that contains resin B on the surface of the core. The external additive includes hydrotalcite particles A. In line analysis in STEM-EDS mapping of the toner, fluorine and aluminum exist inside the hydrotalcite particle A. The value F/Al of the ratio of the atomic concentration of the fluorine to the atomic concentration of the aluminum in the hydrotalcite particle A, which is obtained from main component mapping of the hydrotalcite particle A according to the STEM-EDS mapping analysis of the toner, is 0.01-0.60.SELECTED DRAWING: None
