    摘要： A developer container includes a container main body (31), a supporting member (32) and an information storage portion (100). The container main body (31) is formed in a cylindrical shape and contains therein the developer for use in image formation. The supporting member (32) supports the container main body (31) rotatably about an axis (L31). The information storage portion (100) is fixed to the supporting member (32) and stores developer associated information of the developer contained in the container main body (31). The information storage portion (100) is connected to an information reading portion provided in an image forming apparatus in such a manner that the information reading portion can read out the developer associated information in the state where the developer container is mounted to the image forming apparatus.

    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.

    摘要翻译： 电子照相调色剂由主要由粘合剂树脂制成的不规则形状的核心颗粒和表面改性微粒组成的调色剂颗粒组成，其首先分散在核颗粒的表面上并附着到核颗粒的表面上，然后固定或形成为 膜上。 基于N 2吸附的调色剂颗粒的BET比表面积小于芯颗粒和表面改性微粒组合在一起的BET比表面积的0.64倍。 此外，该值是作为完美球体的假想调色剂颗粒的BET比表面积的1.07倍。 因此，调色剂不容易出现由表面改性微粒的剥离，分离等引起的成膜，调色剂飞散和起雾等问题，也不会由于球形调色剂颗粒导致差的清洁。 此外，由于调色剂通过表面改性微粒定量地掌握核心颗粒的表面的状态而被制造，所以它是处于稳定状态的调色剂。

    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.

    摘要： The present invention provides electrophotographic printing-use toner capable of producing a quality image, without depending on excessive addition of a fluidizing agent, even after maintained at high temperature which causes toner to aggregate. The electrophotographic printing-use toner constituting two-component developer with magnetic powder carrier, made of a toner mother particle including binding agent synthetic resin and a coloring agent, whose surface is added with a fluidizing agent is manufactured so that a ratio of ΔQ h /ΔQ s is not less than 0.37, more preferably not less than 0.45, where ΔQ s is a charging rate of the toner mother particle, at a start of mixing with respect to the magnetic powder carrier, maintained at normal temperature, and ΔQ h is a charging rate of the toner mother particle, at the start of mixing, maintained under a condition of temperature and time which causes the electrophotographic printing-use toner to aggregate.
