Claim Text:
1. A decolorizable toner, comprising: colorant particles which contain a color developable compound, a color developing agent, and a decolorizing agent, and have a capsule structure coated with an outer shell; release agent particles; and a polyester binder resin which is contained in an amount of 60 to 80% by mass with respect to the total amount of components to be contained in the toner particles, wherein the components comprise the colorant particles, the release agent particles and the binder resin, wherein the toner is produced by mixing a dispersion of the colorant particles and a dispersion of the release agent particles to form a dispersion of the colorant particles and the release agent particles, aggregating the colorant particles and the release agent particles to produce a dispersion of first aggregates, mixing a dispersion of resin particles containing the polyester binder resin and the dispersion of the first aggregates, and aggregating the first aggregates and the resin particles to coat the first aggregates with the resin particles, thereby producing second aggregates, and fusing the second aggregates to obtain the toner, wherein the colorant particles are contained in an amount of 10% by mass or more with respect to the total amount of the components to be contained in the toner.
