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), and 100 kcps < [Sr] < 800 kcps (2). La présente invention concerne un toner qui sert à développer une image latente électrostatique et qui comprend une pluralité de particules de toner. Chaque particule de la pluralité de particules de toner comprend un additif fixé à une surface de la particule, de telle sorte que, lorsque la pluralité de particules de toner sont mesurées par spectrométrie par fluorescence aux rayons X (XRF), une intensité de fluorescence aux rayons X de lanthane [La] (unité : kcps) et une intensité de fluorescence aux rayons X de strontium [Sr] (unité : kcps) mesurées par la spectrométrie XRF du toner satisfont les conditions (1) et (2) suivantes : 0,2 kcps < [La] < 2 kcps (1), et 100 kcps < [Sr] < 800 kcps (2).
