    摘要： A toner exhibits excellent image characteristics, and also has an excellent charging property even if the toner is used in a cleaning-simultaneous-with-developing system having a direct injection charging mechanism. The toner includes toner particles and non-magnetic metallic-compound fine particles. The weight average particle diameter of the toner is 3.0 μm to 12.0 μm. The metallic-compound fine particles are conductive metallic-compound fine particles having a specific surface area (cm2/cm3) of 5×105 to 100×105; a medium diameter (D50) of 0.4 μm to 4.0 μm with respect to a volume-based particle diameter distribution, the medium diameter (D50) being smaller than the weight average particle diameter of the toner; and a 90% particle diameter D90 of 6.0 μm or less with respect to a volume-based particle diameter.

    摘要： A toner of the present invention comprises at least a binder resin comprising as a main component a polyester resin, a wax, and a colorant, in which in case of measuring a wettability of the toner with respect to a mixed solvent of methanol and water in terms of an optical transimittance at an optical wavelength of 780 nm, a methanol concentration of the mixed solvent is in a range of 45 to 65% by volume when an optical transmittance is 80% and 10%, respectively; a melt index (MI) is of 0.1 to 10 g/10 min at a temperature of 125° C. and a load of 5 kg; the toner comparises a resin component insoluble to tetrahydrofuran (THF insoluble component) in an amount of 5 to 40% by mass based on a mass of the binder resin; and the toner comprises a THF soluble component having a main peak in a molecular weight region of 3,000 to 20,000, and has a proportion of a component having a molecular weight of 10,000 or less in the THF soluble component is 50% by mass or more, according to a chromatogram of the THF soluble component measured by gel permeation chromatography. According to the toner of the present invention, it is possible to control lowering of an image density after leaving under a high temperature and high humidity environment, and a decline in the image density due to a charge-rise phenomenon upon low rate printing. Further, the toner has excellent fixing property and high temperature offset characteristic, and occurring of the end-offset is controlled.

    摘要： A toner for developing electrostatic images is constituted as a powdery mixture of toner particles, inorganic fine powder, resin fine particles, and metal oxide particles. The toner has a weight-average particle size of 4-12 .mu.m and contains at most 30% by number of particles having a particle size of at most 3.17 .mu.m. The inorganic fine powder has an average primary particle size of 1-50 nm. The resin fine particles have an average particle size of 0.1-2 .mu.m and a shape factor SF1 of at least 100 and below 150. The metal oxide particles have an average particle size of 0.3-3 .mu.m and a shape factor SF1 of 150-250. The toner is effective for preventing toner sticking onto and ununiform abrasion of the electrostatic image-bearing member to allow the formation of high-quality images for a long life.

    摘要： An image-forming method is disclosed. A color toner image formed on an electrostatic latent image carrier is transferred onto one surface of a transfer material and fixed on the transfer material by a fixing means through heating and melting. An other color toner image formed on the electrostatic latent image carrier is transferred onto an other surface opposite to the color toner-fixed surface of the transfer material and fixed, thereby forming color images fixed on both surfaces of the transfer material. The color toner forming the color images contains toner particles directly obtained by suspension polymerization, and the toner particles contain wax.
