摘要: Disclosed is a toner obtained by coating surfaces of core particles including at least a binder resin having a carboxyl group and a coloring agent with successive coatings of a water-soluble crosslinking agent capable of crosslinking with a carboxyl group and a water-soluble polymer having a carboxyl group, which have been successively applied on the core particles and crosslinked with each other. The thus-formed toner is provided with a good harmony of favorable fixability represented by a low lowest fixable temperature and favorable storage stability represented by little aggregation after standing at 50° C. for 8 hours.

摘要: Encapsulated toner particles are formed by: aggregating core material particles containing at least a colorant and a core material resin in an aqueous dispersion medium to form core particles; adding coating resin particles into the aqueous dispersion medium during progress of the formation of the core material at a point of time when the volume-based median particle diameter of the core particles formed by the aggregation reaches 30 to 83% of that of desired toner particles; and continuing the aggregation to form a coating layer composed of a composite aggregate of the core material particles and the coating resin particles on the core material. In the thus-obtained toner, the colorant is uniformly and well incorporated in the toner particles, and therefore, the coloring ability is improved without causing a problem of release of fine powder.

摘要: Disclosed is a process for production of a decolorable toner, including: aggregating dispersed fine particles of a color material comprising at least a color-forming compound, a color-developing agent and a decoloring agent with dispersed fine particles comprising at least a binder resin comprising a polyester resin to form aggregates in an aqueous medium, adding a reactive polymer having an oxazoline group in to the aqueous medium, and fusing the aggregates in the aqueous medium. As a result, it becomes possible to produce a decolorable toner which suppresses the generation of fine powder due to the release of fine particles of an erasable color material from the toner.
