Claim:
A toner, comprising: a colorant; and a binder resin; wherein: the toner is prepared by: dissolving or dispersing at least the colorant, a precursor of the binder resin having a site capable of reacting with an active hydrogen group-containing compound and the active hydrogen group-containing compound in an organic solvent to prepare a toner constituent mixture liquid; dispersing or emulsifying the toner constituent mixture liquid in an aqueous medium while subjecting the precursor to a reaction with the active hydrogen group-containing compound to prepare a toner dispersion; and removing the organic solvent from the toner dispersion to prepare the toner; the binder resin comprises at least a modified polyester; the modified polyester is derived from the precursor which has an isocyanate-derived functional group; an Sn content of the toner is 800 ppm or less; a content of Ti derived from a polyesterified catalyst in the toner is 10 ppm to 200 ppm; and a content of Bi derived from an isocyanated catalyst in the toner is 10 ppm to 200 ppm.
