    • An image forming method includes: performing a first gloss processing and a second gloss processing. The first gloss processing includes: heating and pressing a processed body which supports a first toner layer containing at least a clear toner [X] onto a first surface of a recording material, while allowing the first toner layer to be closely adhered to a gloss processing belt; and cooling the same. The second gloss processing includes heating and pressing a processed body which supports a second toner layer containing at least a clear toner [Y] onto a second surface of the recording material, while allowing the second toner layer to be closely adhered to the gloss processing belt; and cooling the same. Here, a storage elastic modulus G′ X (150) at 150° C. of the clear toner [X] is lower than a storage elastic modulus G′ Y (150) at 150° C. of the clear toner [Y].
    • 图像形成方法包括:执行第一光泽处理和第二光泽处理。 第一光泽处理包括:加热和加压处理体,其将至少含有透明调色剂[X]的第一调色剂层支撑在记录材料的第一表面上,同时允许第一调色剂层紧密附着于光泽处理 带; 并进行冷却。 第二光泽处理包括加热和加压处理体,其将含有至少不透明调色剂[Y]的第二调色剂层支撑在记录材料的第二表面上,同时允许第二调色剂层紧密附着到光泽处理带 ; 并进行冷却。 这里,透明调色剂[X]的150℃下的储能弹性模量G'X(150)低于透明调色剂[Y]的150℃下的储能弹性模量G'Y(150)。

    • An objective is to provide a carrier exhibiting stable charge providing ability in which sufficient charge can be provided to toner having a small particle diameter, and no image contamination such as fog caused by toner scattering via lack of electrification is generated. Another objective is to provide a carrier capable of maintaining a charging level of no interference for image formation even under the image forming condition at which a charging level for printing a number of prints continuously is difficult to be maintained. Disclosed is a carrier comprising a core particle made of ferrite possessing Mg and coated thereon, a resin, wherein the core particle has a ratio of the number of irregular-shaped core particles of at most 5%, based on the total number of core particles, and a surface of the core particle has grains having a maximum grain diameter of 2-5 μm.
