    摘要: A method for manufacturing a developing agent includes forming a toner particle by adding an aggregating agent to a dispersion containing fine particles containing a binder resin and a colorant to allow aggregation and melt adhesion to occur, wherein the pH of the dispersion satisfies the formula (1) below, when denoting pH before the addition of the aggregating agent by pH(A), the pH of the dispersion after the addition of the aggregating agent by pH(B), and the pH of the dispersion after the melt adhesion by pH(C): 0.90≧pH(C)/pH(A)≧0.25 and 1.00≧pH(C)/pH(B)≧0.30  (1).

    摘要: A developing agent comprises first and second resin fine particles containing a colorant and a release agent and different in weight average molecular weight, and a concentration of the release agent which is softened at a low temperature in the second resin fine particles having the high weight average molecular weight is higher than a concentration of the release agent in the first resin fine particles, whereby thermal properties dependent on the weight average molecular weight of the resin fine particles are made uniform and fixability of the developing agent is improved.

    摘要: In a manufacturing method of a resin for developing agent, a first polymerization agent is added in an aqueous medium; a radical polymerizable monomer is polymerized in the presence of a chain transfer agent to form a low molecular substance resin particle; after consuming the chain transfer agent, a second polymerization initiator is added in the aqueous medium; and the remaining monomer is polymerized to form a high molecular substance resin particle, thereby improving fixability of the developing agent.
