    摘要： A method of manufacturing electrophotographic toner according to the present invention includes the step of mixing at least toner particles and an additive for a predetermined mixing time to produce the toner, with the predetermined mixing time being set within a range from a first mixing time, at which chargeability of the toner (which changes according to the duration of mixing of the toner particles and the additive) shows a singular point, through a second mixing time, at which preservation of the toner (which also changes according to the duration of mixing) shows a singular point. By this method, a mixing time which maximizes the effects of the additive can be easily set. Accordingly, using a method simpler than conventional methods, a toner can be obtained which has good characteristics with regard to both chargeability and preservation.

    摘要： An electrophotographic toner is made up of toner particles composed of irregularly-shaped core particles made chiefly of binder resin, and surface-modifying fine particles which are first dispersed over and attached to the surface of the core particles, and then affixed or formed into a film thereon. The BET specific surface area, based on N 2 adsorption, of the toner particles is less than 0.64 times the BET specific surface area of the core particles and surface-modifying fine particles combined together. Further, this value is 1.07 times the BET specific surface area of hypothetical toner particles which are perfect spheres. Consequently, the toner is not prone to problems such as filming, toner scattering, and fogging which are caused by peeling, separation, etc. of the surface-modifying fine particles, nor to poor cleaning due to spherical toner particles. Further, since the toner is manufactured with a quantitative grasp of the state of modification of the surface of the core particles by the surface-modifying fine particles, it is a toner in a stable state.

    摘要： Electrophotographic toner particles (1) contain a binder resin (2), wax particles (3) and a coloring agent, the wax particles (3) being dimensioned to have a major axis (L) of not more than 6.0 µm and a major axis (L)/minor axis (S) ratio of 1.4 to 4.0. The binder resin preferably has a melt index of 5.0 to 11.0 and a dielectric loss tangent (tan 6) of not more that 5.0. This arrangement prevents the wax particles (3) inside the toner particles (1) or at the surface of the toner particles (1) being exposed or projecting to provide superior offset-reduction during fixing and to reduce surface wax contamination.
