Disclosed is a toner including toner particles each including a core portion that contains a binder resin, and a surface layer containing an organosilicon polymer, in which each of the toner particles contains a polyvalent metal element having a resistivity of 2.5×10 −8 Ω·m or more and 10.0×10 −8 Ω·m or less at 20° C., and when the toner particles are subjected to X-ray fluorescence analysis, a net intensity originating from the polyvalent metal element is 0.10 kcps or more and 30.00 kcps or less. |
