    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.
