摘要： In a toner T of the present invention, the liberated mother particle ratio is set to be 10% or less and the liberated silica particle ratio is set to be 0.2–10%, thereby reducing the possibility that the liberated mother particles 18′ and the mother particles 18 with silica particles 19 therein will be fused on toner-contact members such as a latent image carrier, a toner carrier, and a toner regulating member, and thus effectively preventing the filming of toner T. Therefore, according to the toner T of the present invention, the durability of the toner-contact members such as the latent image carrier, the toner carrier, and the toner regulating member can be improved. In addition, a large quantity of heat for heat fixing can be prevented from being consumed by the silica particles 19 because the amount of silica particles 19 is suitably set, and heat can be hardly transferred to mother particles 18 having a low melting point because the mother particles 18 are coated with a desired amount of silica particles 19. Therefore, the low-temperature fixing property can be improved.
摘要翻译：在本发明的调色剂T中，释放母粒子比率设定为10％以下，游离二氧化硅粒子比率设定为0.2〜10％，从而降低了释放母粒子18'和其中具有二氧化硅颗粒19的母粒子18将熔融在调色剂接触部件上，例如潜像载体，调色剂载体和调色剂调节部件，从而有效地防止调色剂T的成膜。因此，根据调色剂T 可以提高调色剂接触构件如潜像载体，调色剂载体和调色剂调节构件的耐久性。此外，由于二氧化硅颗粒19的量被适当地设定，因此可以防止大量的热定影用于二氧化硅颗粒19的消耗，并且由于这些二氧化硅颗粒的热量几乎不能转移到具有低熔点的母体颗粒18 母粒子18涂覆有所需量的二氧化硅颗粒19。因此，可以提高低温定影性。

摘要： A non-magnetic single-component toner 8 of the present invention has toner mother particles 8a, and external additives 12 comprising: two hydrophobic silicas 13, 14 of which particle diameters are different from each other, i.e. a mean primary particle diameter of 7 nm to 12 nm and a mean primary particle diameter of 40 nm to 50 nm, and a hydrophobic rutile/anatase type titanium oxide 15 having a spindle shape of which major axial diameter is in a range from 0.02 nm to 0.10 nm and the ratio of the major axial diameter to the minor axial diameter is set to be 2 to 8, wherein the external additives 12 adhere to the toner mother particles 8a. By the hydrophobic silicas 13, 14 having work function smaller than the work function of the toner mother particles 8a, the negative charging property is imparted to the toner mother particles 8a and the fluidity is also insured. On the other hand, by mixing and using hydrophobic rutile/anatase type titanium oxide particles 15 having work function larger than or equal to the work function of the toner mother particles 8a together with the hydrophobic silicas 13, 14, the non-magnetic single-component toner 8 is prevented from excessively charged. Therefore, the amount of fog toner on non-image portions is reduced, the transfer efficiency is further improved, the charging property is further stabilized, and the production of reverse transfer toner is further inhibited.
摘要翻译：本发明的非磁性单组分调色剂8具有调色剂母粒子8a和外部添加剂12，其包含：两个粒径彼此不同的疏水性二氧化硅13,14，即平均一次粒径为7nm 平均一次粒径为40nm〜50nm的疏水性金红石/锐钛矿型氧化钛15，主轴的直径为0.02nm〜0.10nm的主轴形状，小轴向直径的主轴径设定为2〜8，其中外部添加剂12粘附到调色剂母粒8a上。通过具有小于调色剂母粒子8a的功函数的功函数的疏水性二氧化硅13,14赋予调色剂母粒子8a的负带电性，并且还保证了流动性。另一方面，通过将功能大于或等于调色剂母粒8a的功函数的疏水性金红石/锐钛矿型氧化钛粒子15与疏水性二氧化硅13,14混合并使用，防止组分调色剂8过度充电。因此，非图像部分上的雾化调色剂的量减少，转印效率进一步提高，充电性能进一步稳定，并进一步抑制反转印调色剂的生产。

摘要： A two-component binder-type magnetic carrier for developing agent comprising a magnetic powder and a binder resin. The carrier particles contain dispersed therein a release agent of the type of a metal soap and have abrasive or collapsible surfaces. By using the developing agent which contains this carrier, the magnetic powder peels off the carrier particle surfaces maintaining a controlled particle diameter and amount. Therefore, the carrier particles possess fresh surfaces at all times, whereby the occurrence of spent toner is effectively prevented and the charging amount of the toner is stably maintained.
