Toner

A toner, comprising:

• a toner particle containing a binder resin and a calcium carbonite fine particle;
• the binder resin containing a crystalline resin having a first monomer unit represented by formula (1)
• where RZ1 represents a hydrogen atom or a methyl group, and R1 represents an alkyl group having 18 to 36 carbon atoms, wherein
• the calcium carbonite fine particle is treated with a fatty acid,
• a content of the calcium carbonite fine particle in the toner particle is 1.0 to 15.0 mass %, and
• a crystallite diameter of a crystal to which a peak within 2θ=29.5°±0.5° is attributed is 10 to 45 nm, and a ratio between a peak intensity within 2θ=26.5°±0.5° and a peak intensity within 2θ=29.5°±0.5° is 0.15 to 0.24 in an X-ray diffraction measurement using a CuKα ray on the toner particle, when θ is a Bragg angle, and the calcium carbonate particle has peaks within a range of 2θ=26.5°±0.5° and 2θ=29.5°±0.5°.
