Claim One:
1. A toner comprising a toner particle containing a binder resin, a colorant, a crystalline polyester, and a release agent, wherein when a cross-sectional image of the toner is observed using a scanning transmission electron microscope, 8-500 domains of the crystalline polyester are present in the cross-sectional image of the toner, the domains having a number-average major diameter of at least 50 nm and not more than 300 nm, a ratio of the domains present in an area from an outline of the cross-sectional image to 25% of a distance between the outline and a centroid of the cross-sectional image, to a total number of the domains present in the cross-sectional image of the toner is 60 to 100 number %, domains of the release agent are present in the cross-sectional image, and a ratio of a total area of the domains of the release agent to an area of the cross-sectional image of the toner is 5.0 to 30.0 area %.
