    • A recording sheet of the present invention comprises a substrate film, a receptor layer for retaining a toner image and a release layer for releasing the receptor layer from a fixing surface of a fixing means, the receptor layer and the release layer being disposed on at least one side of the substrate film in this order from a position of the substrate film, wherein the release layer contains a release agent having compatibility to toner and releasing ability to the fixing surface. A preferable release agent is wax, particularly wax having a polar group in its molecular structure, such as carnauba wax and candelilla wax. The recording sheet of the present invention can provide a high quality of the toner image with no occurrence of fusion to the fixing surface and cohesive failure of the receptor layer even when the thermal fixing is carried out with no oil supplied to the fixing surface of the fixing means.
    • 本发明的记录片材包括基材膜,用于保留调色剂图像的接收层和用于从固定装置的固定表面释放接收层的剥离层,所述接收层和剥离层至少设置在 从衬底膜的位置起依次形成衬底膜的一侧,其中剥离层含有与调色剂相容的释放剂和对固定表面的释放能力。 优选的脱模剂是蜡,特别是其分子结构中具有极性基团的蜡,例如巴西棕榈蜡和小烛树蜡。 本发明的记录片材可以提供高质量的调色剂图像,即使在没有供给至固定表面的固定表面的油的情况下进行热定影时,也不会对固定面发生熔融和接收层的内聚破坏 固定装置
