Summary:A toner comprising: a toner particle containing a resin component and a wax; and an inorganic fine particle on the surface of the toner particle, wherein, in a cross section of the toner particle, domains containing the wax are observed, and when among the domains, domains having a major diameter of 10-300 nm are defined as domains S, an occupation area percentage of which a ratio of a total sum of areas occupied by the domains S in a region from a surface of the toner particle to a depth of 600 nm in the cross section with respect to an area of the region, is 3.0-15.0%, and wherein the inorganic fine particle contains a fine particle A having a volume resistivity of 1.0×103 to 3.0×105 Ω·cm, and having a relative permittivity εr of 100 or more.
