摘要：
According to one embodiment, a method for producing a developing agent includes pulverizing a mixture in the form of coarse particles of a toner material including a coloring agent and a binder resin by mechanical shearing, aggregating and fusing the resulting fine particles. The solid content concentration in a dispersion liquid including the aggregated particles is from 5.0% to 40.0%, the volume average particle diameter of the aggregated particles is from 1.0 μm to 10.0 μm, and the ratio of the standard deviation to the volume average particle diameter is 30.0% or less.
