    摘要： [Object] The purpose of the present invention is to provide a charge control agent for polymerized toners and particularly for color toners, which has a large charge amount and environmentally stable charging characteristics.[Solving Means] Since a charge control agent including a pyrazolone derivative represented by a general formula (1) or a salt of the derivative as an active ingredient has a large charge amount and excellent environmental stability of charging, it has an excellent charge-imparting effect for use in polymerized toners and particularly in color toners. (in the formula, R1, R2, and R3 each independently represent a substituted or unsubstituted C1 to C20 linear or branched alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted condensed polycyclic aromatic group.)

    摘要： Provided is a toner for developing electrostatic images, which is less likely to cause filming, is excellent in printing durability, and is less likely to cause fog under a high temperature and high humidity environment. The toner for developing electrostatic images is a toner containing colored resin particles that contains a binder resin, a colorant and a charge control agent, and external additives, wherein the external additives include at least: silica fine particles A, silica fine particles B, and electroconductive metal oxide fine particles C; wherein the silica fine particles. A and B are silica fine particles surface-hydrophobized with at least one hydrophobizing agent; wherein the electroconductive metal oxide fine particles C have an electrical resistance of 70 Ωcm or less and contain antimony-doped tin oxide.

    摘要： A toner is provided that exhibits a high long-term image stability even during high-speed printing and that also exhibits an excellent environmental stability. The toner comprises a binder resin, a colorant, and a nonionic surfactant, wherein the nonionic surfactant has an oxyethylene group (EO) and an oxypropylene group (PO) and has a ratio of the number of moles of the oxypropylene group to the number of moles of the oxyethylene group (PO/EO) of at least 0.01 and not more than 5.00; and when A (μg/g) is defined as a nonionic surfactant content on the surface of the toner that can be extracted by methanol from 1 g of the toner and B (m2/g) is defined as a theoretical specific surface area determined from a toner particle diameter distribution obtained by a precision particle diameter distribution analyzer that operates based on an aperture electrical resistance method, a ratio A/B is at least 100 μg/m2 and not more than 9000 μg/m2.
