Abstract
A toner includes toner particles which contain a binder resin, a colorant, a wax, and a resin A having an organic polysiloxane structure; the amount of Si atoms of the toner particles is 4.5 to 10.0; in an analysis of a cross-section of each toner particle, in a surface layer region R from the periphery of the cross-section of the toner particle to the inside at a distance of 10.0% of the particle diameter in the cross-section of the toner particle, the content of Si atoms derived from the organic polysiloxane structure is 90.0% or more with respect to the total amount of Si atoms contained in the toner particle; and in a line analysis along a straight line between the periphery of the surface layer region R and a gravity center of the cross-section, an intensity count of Si atoms in the toner particle satisfies formula Si>Si>Si>Si≥0.
