    摘要： The developer in accordance with the present invention includes toner, and a carrier having a core material the surface of which is coated with a coating layer made of a polymer, the coating layer having a resistance value sufficient to minimize the counter electric charge remaining in the coating layer, and the toner having any of characteristic values required for preventing a counter electric charge remaining in the coating layer from being increased. The use of the developer of the present invention not only prevents the occurrence of so-called carrier scattering, to thereby prevent blanking, but also produces an image of high quality having a high initial image density.

    摘要翻译： 根据本发明的显影剂包括调色剂和具有芯材料的载体，其表面涂覆有由聚合物制成的涂层，所述涂层具有足以使剩余的反电荷最小化的电阻值 涂层，并且具有防止在涂层中剩余的相对电荷所需的任何特征值的调色剂增加。 使用本发明的显影剂不仅防止所谓的载体散射的发生，从而防止消隐，而且还产生具有高初始图像浓度的高质量的图像。

    摘要： An electrophotographic toner comprising a binder resin and a colorant, which is used in electrophotographic process employing a flash fixing system for fixation of a transferred toner image, wherein the binder resin is a polyester resin which partially contains a chloroform-insoluble content; and the toner contains a polypropylene resin and an ester type structure resin represented by the following formula (I); wherein p, q, m and n each represents a positive integer of 16 to 22 and R may be the same or different and each represents a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms. The electrophotographic toner is capable of remarkably enhancing the fixation strength of the toner and inhibiting the occurrence of voids during the printing and the occurrence of fuming and odor during the fixation.
