    摘要： In a toner having toner particles which comprise toner base particles containing at least a colorant, a release agent and a polar resin, and an inorganic fine powder, the polar resin is a resin having at least a polyester unit, synthesized in the presence of an aromatic carboxylic acid titanium compound used as a catalyst, and has an acid value of from 3 mgKOH/g to 35 mgKOH/g. The toner base particles are obtained by carrying out granulation in an aqueous medium, and the toner has a weight-average particle diameter of from 4.0 μm to 10.0 μm.

    摘要： A toner includes toner particles and an inorganic fine powder mixed with the toner particles. The toner particles contain a binder resin, a coloring agent, a releasing agent, and a sulfur-containing resin. The toner particles contain at least one element selected from the group consisting of magnesium, calcium, barium, zinc, aluminum, and phosphorus and satisfy the relationship: 4≦T/S≦30 wherein T represents the total content of the element in ppm, and S represents the content of sulfur in ppm. The weight-average particle diameter (D4) of the toner is in the range of 3 to 10 μm. The average circularity of the toner is within the range of 0.950 to 0.995.
