Toner and method for producing toner

A toner, comprising:

• a toner particle comprising an organic pigment, a binder resin and a calcium carbonate particle;
• and
• a content ratio of the calcium carbonate particle in the toner particle being 3.0 to 15.0 mass %;
• peaks being present in ranges of diffraction angle (2θ)−26.5°±0.1° and diffraction angle (2θ)=29.5°±0.1° when an X-ray diffraction measurement is performed on the toner using CuKα rays;
• a crystallite size of the calcium carbonate calculated from a peak in the range of diffraction angle (2θ)−29.5°=0.1° being 10 to 45 nm;
• and
• a value of a ratio of peak intensity in the range of diffraction angle (2θ)=26.5°±0.1° relative to peak intensity in the range of diffraction angle (2θ)−29.5°=0.1° is 0.15 to 0.24, wherein
• in a solid-state NMR measurement at 60° C. using a solid fraction obtained in Procedure 1 as a sample, a transverse relaxation time T2 of a peak observed between 1.5 and 2.5 ppm is 0.08 to 0.13 ms, and
• Procedure 1 comprises preparing a sucrose concentrate by adding 160 g sucrose to 100 mL ion-exchanged water, and dissolution therein while under warming in hot water, producing a dispersion by adding 31 g of the sucrose concentrate and 6 mL surfactant to a centrifuge tube, adding 2.0 g of the toner to the dispersion, breaking toner clumps using a spatula, shaking the centrifuge tube in a shaker followed by removing precipitate through solution centrifugation at 3500 rpm for 30 minutes at a rotation radius of 3 cm, filtering a floating solid fraction in a vacuum filter, and is thereafter dried in a dryer for at least 1 hour dissolving 1 g of the obtained solid fraction in 20 mL of chloroform, centrifuging at 15000 rpm at a rotation radius of 3 cm for 180 minutes, discarding the supernatant, adding 20 mL of chloroform, repeating the same operation twice, and drying a precipitated solid fraction in a dryer for at least 5 hours.
