摘要： In toner 1 containing a binder resin 2, wax particles 3 and a coloring agent, the wax particles 3 are designed so that the ratio of major axis/minor axis is set in the range of 1.4 to 4.0 and so that the major axis L is not more than 6.0 .mu.m. Moreover, the melt index of the binder resin ranges from 5.0 to 11.0, and the dielectric loss tangent (tan .delta.) is not more than 5.0. This arrangement prevents the wax particles 3 inside the toner 1 or at the toner 1 surface layer from exposing to or sticking out of the toner 1 surface, thereby making it possible to provide a superior offset-reducing property during the fixing process and electrophotographing toner that can reduce wax contamination on the surface of the toner-bearing body.
摘要翻译：在含有粘合剂树脂2，蜡颗粒3和着色剂的调色剂1中，蜡颗粒3被设计成使得长轴/短轴的比率设定在1.4至4.0的范围内，并且使得长轴L为不超过6.0亩。此外，粘合剂树脂的熔融指数为5.0〜11.0，介电损耗角正切（tanδ）为5.0以下。这种布置防止调色剂1内或调色剂1表面层上的蜡颗粒3暴露于或从调色剂1表面露出，从而使得可以在定影过程中提供优异的抵消减小性能和电子照相调色剂，可以减少调色剂承载体的表面上的蜡污染。

This electrostatic charge image-developing toner prevents an offset phenomenon on the surface of a fixing roller, and does not adhere to and fuse on a photoreceptor drum to cause no stripy and dotwise stain on a reproduced image, that is, preventing a so-called filming phenomenon. The toner also prevents an offset phenomenon on the photoreceptor drum.

摘要： A two-component developer for electrophotography includes a toner comprising toner particles and an external additive composed of a compound of imidazole series or an imidazole derivative. The external additive has a volume median particle size below that of the toner particles, or of 0.1 to 100 .mu.m. The amount of external additive is 0.001 to 5% by weight based on the weight of the toner particles. As a result, scattering of toner may be prevented and the formation of fog in the background may be reduced. In addition, the electrostatic charge characteristics of the toner may be improved and the electrostatic charge rises in a satisfactory manner.

摘要： A magnetic member is arranged at a position on the downstream side with respect to the rotational direction of a developing sleeve, outside the developer conveyance path where the magnetism from the magnetic member has no influence on the magnetic field of the developing magnetic pole. When the magnetic member is arranged with its N pole facing the developing sleeve, the magnetic attractive force from the magnetic member weakens the developer's attraction to the peripheral surface of the developing sleeve. When the magnetic member is arranged with its S pole facing the developing sleeve, the developer being conveyed along the developer conveyance path is magnetized in such a direction as to repel the peripheral surface of the developing sleeve. In either case, the adhering state of the developer to the peripheral surface of the developing sleeve having passed through the developing position is unstable, so that the developer having adhered to the developing sleeve will easily drop off from the developing sleeve after passage of the developing position.
摘要翻译：磁性构件相对于显影套筒的旋转方向在下游侧的位置处布置在显影剂输送路径的外侧，其中磁性构件的磁性对显影磁极的磁场没有影响。当磁性构件以其N极面向显影套筒布置时，来自磁性构件的磁性吸引力削弱了显影剂对显影套筒周边表面的吸引力。当磁性构件以其S极面向显影套筒布置时，沿着显影剂输送路径输送的显影剂沿着排斥显影套筒的周面的方向被磁化。在任一种情况下，显影剂到已经通过显影位置的显影套筒的周面的粘附状态是不稳定的，使得附着在显影套筒上的显影剂在显影剂通过后容易从显影套筒脱落位置。

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。
