摘要： An electrophotographic toner is prepared by using a binder resin having an acid value of 5 to 15 mgKOH/g, a salicylic metal complex, a colorant, and a releasing agent. In the preparation determination for the third root distribution of a light emission voltage by helium atmospheric pressure microwave induction plasmas for carbon atoms derived from the binder resin and metal atoms derived from the salicylic metal complex is made based on a value measured by a micro-particle measuring apparatus including a normal pressure or atmospheric pressure space, a capillary tube inserted at one end in the space, a microwave source, a cavity, a quartz tubular reactor, a discharge means, an analyses means, and a signal detection portion. The absolute deviation showing the scattering of approximate straight lines approximated by a least squares method is controlled to be 0.08 or less.

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.sub.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首先分散在核颗粒表面上并附着在核颗粒表面上的表面改性微粒组成的调色剂颗粒组成，然后固定或形成为 膜上。 调色剂颗粒的基于N2吸附的BET比表面积小于核心颗粒的BET比表面积和结合在一起的表面改性微粒的0.64倍。 此外，该值是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而导致不良清洁。 此外，由于调色剂通过表面改性细颗粒对芯颗粒的表面的修饰状态的定量掌握来制造，所以它是调色剂处于稳定状态。

摘要： The extra-fine toner arising in the toner producing process, is returned to the mixing step where it is mixed again with the binder resin and the coloring agent, and the compound is sent out to the kneading step. In this procedure, the particle size of the binder resin is set in accordance with the particle size and blending amount of the extra-fine toner, the kind of the binder resin, etc. By using the binder resin having the thus determined particle size, the amount of the binder to be fed into the mixer or the amount of the compound ejected from the mixer are maintained uniform. Further, when the extra-fine toner is mixed with the starting materials, the blending ratio of the extra-fine toner to the starting material is set between 5 wt. % and 10 wt. %, and the blending ratios of the charge control agent and the coloring agent are set equal to those of the normal process where no recycled toner is added.
