    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： According to one embodiment, a method for producing a developing agent including aggregating fine particles of a toner material containing a binder resin and a coloring agent in a dispersion liquid in which the fine particles are dispersed in an aqueous medium to form aggregated particles, and washing the aggregated particles and drying the washed aggregated particles, forming toner particles is provided. An electrical conductivity of the toner particles is measured by a toner electrical conductivity evaluation method. A sample toner is prepared by adhering an additive to surfaces of the toner particles, and a content ratio of a sodium element to a carbon element in a region to which the additive is not adhered of the toner is measured. The washing of the toner particles is repeated until each of the measurement values becomes a predetermined reference value or less.

    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.
