    • The present invention provides a toner comprising a binder resin, a colorant, and a releasing agent wherein the releasing agent has an endothermic starting temperature of 40° C. or more and a melting point of 120° C. or less which are measured using a differential scanning calorimeter, the binder resin contains a linear resin and a non-linear resin, the content of the releasing agent existing at the surface of toner particles is 0 to 30% by weight, and the shape factor MLS2 of the toner particles is from 100 to 130. Preferably a mixture of a linear Polyester and a non linear polyester is used as the binder resin. Preferably the weight average molecular weight of the linear polyester is 2.0×103 to 5.0×104. The toner of the present invention has excellent developing characteristics and transfer characteristics, and superior offset resistance even in an oil-less fixing system. When recording a color image using the toner of the present invention, the resulting image has high quality and the OHP transmittancy is improved.
    • 本发明提供一种包含粘合剂树脂,着色剂和脱模剂的调色剂,其中脱模剂的吸热起始温度为40℃以上,熔点为120℃以下,使用 差示扫描量热计,粘合剂树脂含有线性树脂和非线性树脂,存在于调色剂颗粒表面的脱模剂的含量为0〜30重量%,调色剂颗粒的形状因子MLS2为 优选使用线性聚酯和非线性聚酯的混合物作为粘合剂树脂。 优选线性聚酯的重均分子量为2.0×10 3〜5.0×10 4。 本发明的调色剂具有优异的显影特性和转印特性,并且即使在无油定影系统中也具有优异的胶印阻力。 当使用本发明的调色剂记录彩色图像时,所得到的图像具有高质量,OHP透过率提高。

    • In a thermal printer for performing printing on the printing surface of a tag which is drawn out from a tag roll and then held and conveyed by a platen and a line thermal head, the thermal printer comprises a thread sweeping means for sweeping away the threads which get on the printing surface of the tag and a tag guide means disposed downstream the conveying direction of the tag for bringing into contact with the side edge of the tag which is opposite to the other side edge thereof to which the threads are attached so that the threads which get on the printing surface of the tag are swept away by the thread sweeping means and the tag is conveyed in the manner that the threads do not contact the tag guide, which eventually prevents the threads from being caught by parts on the conveying route or prevents the tag from being printed on the printing surface thereof while the threads remain getting on the printing surface. Furthermore, a roll holder for holding the entire tag roll is attached to a detachable roll presser plate facing the threads, thereby preventing the threads from being put between the roll presser plate and the roll holder.
