    摘要： As a first dispersion liquid containing first fine particles and a second dispersion liquid containing second fine particles, those satisfy the relationship represented by the following formula (1) are used, and these two dispersion liquids are mixed with each other, and an aggregating agent and a pH adjusting agent are added thereto in sequence, whereby encapsulation is achieved by selective formation of core particles through aggregation of the first fine particles and shells through aggregation of the second fine particles. 15 mV≧|Z2−Z1|≧5 mV  (1) In the formula, Z1 and Z2 represent zeta potentials of the first dispersion liquid and the second dispersion liquid, respectively, measured when aluminum sulfate is added to each dispersion liquid in an amount of 1% by weight based on the solid content in each dispersion liquid.

    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： 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.
