Summary:A toner for developing an electrostatic latent image includes a plurality of toner particles. Each of the plurality of toner particles includes an additive attached to a surface of the particle, such that, when the plurality of toner particles are measured by X-ray fluorescence (XRF) spectrometry, an X-ray fluorescence intensity of lanthanum [La] (unit: kcps) and an X-ray fluorescence intensity of strontium [Sr] (unit: kcps) measured by the XRF spectrometry of the toner satisfy the following conditions (1) and (2):0.2 kcps<[La]<2 kcps   (1),and100 kcps<[Sr]<800 kcps   (2).
