摘要： A carrier excellent in durability and environmental stability and a two-component developing agent is provided. In the carrier, a core material is coated with a resin, and the coating resin is formed on the core material such that the coating resin comes to be in an amount of 5% by weight to 20% by weight on the basis of a weight of the core material, thereby enhancing durability. Further, the coating resin contains fine particles of titanium oxide, thereby enhancing environmental stability.

摘要： A two-component developing agent containing a carrier which can maintain a charge-imparting property to a toner at a high level for a long period of time, does not generate flying of the carrier and can correspond to an image forming apparatus of present day having a long operation life and can form a high-quality image having high image density and sharpness, is provided. In the two-component developing agent containing a carrier in which a resin coating layer is formed on a surface of a core material, and a toner, in which an X-ray intensity of an alumina particle by a fluorescent X-ray analysis, the amount of the alumina particle to be used to the resin coating layer is adjusted such that it comes to be smaller than the X-ray intensity by the fluorescent X-ray analysis of a metal contained in a largest amount in the core material.
摘要翻译： 含有能够长时间保持高调色剂的电荷赋予性的载体的双组分显影剂不会产生载体的飞散，并且可以对应于当前的图像形成装置，具有 提供长的使用寿命并且可以形成具有高图像密度和清晰度的高质量图像。 在含有在芯材表面上形成有树脂被覆层的载体的双组分显影剂和通过荧光X射线分析的氧化铝颗粒的X射线强度的调色剂中， 调整使用于树脂被覆层的氧化铝粒子的量，使其比通过核心材料中最大量含有的金属的荧光X射线分析的X射线强度小。

摘要： A non-magnetic single component developing device that is included in combination with a photoreceptor in an image forming apparatus 1 of the electro-photographic system. The non-magnetic single component developing device includes a developing roller, a supplying roller, a doctor, a toner bath and a stirring blade. The supplying roller contains a rubber foam at least in its surface layer portion, the rubber foam including closed cells and open cells and having a foam ratio (porosity) of 0.75 to 0.85 and an average foam cell diameter of 350 to 500 μm.
