    • The invention provides an image forming method, comprising transferring a toner image to an electrophotographic recording sheet, layering the electrophotographic recording sheet on a fixing belt and heating and pressing the sheet, and cooling the electrophotographic recording sheet and separating the sheet from the fixing belt. The electrophotographic recording sheet comprises a support comprising cellulose pulp-containing base paper and a toner image-receiving layer comprising a thermoplastic resin disposed on the support. A shrinkage percentage of the electrophotographic recording sheet in a CD direction in the heating step is 1.3% or less. The support preferably further comprises either a polyolefin-containing layer or a coating that contains at least one selected from the group consisting of kaolin, a pigment, a resin, a rubber latex, or a polymer material and that is provided on one or both surfaces of the base paper.
    • 本发明提供了一种图像形成方法,包括将调色剂图像转印到电子照相记录片材上,将电子照相记录纸层叠在定影带上并加热和压制片材,并冷却电子照相记录片材并将片材与定影带分离。 电子照相记录纸包括含有含纤维素纸浆的原纸的支持体和包含设置在支持体上的热塑性树脂的调色剂图像接收层。 在加热步骤中,电子照相记录纸在CD方向上的收缩率为1.3%以下。 优选地,所述载体还包含含聚烯烃层或包含选自高岭土,颜料,树脂,橡胶胶乳或聚合物材料中的至少一种的涂层,并且其设置在一个或两个表面上 的原纸。

    • In the image forming process of the present invention wherein a toner is fixed on an electrophotographic image-receiving sheet using a belt fixing and smoothing device, the relationship among the temperature of a heating and fixing roller, the melting point of a toner wax, and the glass transition point of a toner binder, the relationship among the temperature of a heating and fixing roller, the melting point of a wax in the image-receiving layer, and the glass transition point of a binder in the image-receiving layer, and the relationship between the polar components of surface free energy of the toner-image-receiving layer before and after image fixing are optimized. The present invention is to prevent offset in the toner and the toner-image-receiving layer of the electrophotographic image-receiving sheet upon releasing of the belt and to avoid deterioration in image quality especially in operation over the long run.
    • 在使用带固定和平滑装置将调色剂固定在电子摄影图像接收片上的本发明的图像形成方法中,加热和定影辊的温度,调色剂蜡的熔点和调色剂蜡的熔点之间的关系 调色剂粘合剂的玻璃化转变点,加热定影辊的温度,图像接收层中的蜡的熔点和图像接收层中的粘合剂的玻璃化转变点之间的关系,以及 图像定影之前和之后的调色剂图像接收层的表面自由能的极性分量之间的关系被优化。 本发明是为了防止在剥离带时电子照相图像接收片的调色剂和调色剂图像接收层中的偏移,并且避免图像质量的恶化,特别是在长时间的操作中。
