摘要

PPROBLEM TO BE SOLVED: To provide toner, with which proper dot reproducibility and high image quality are obtainable without problems in transportability and without the degradation in image density, by using the evaluation which is high in accuracy of flow properties and is free of individual differences. PSOLUTION: The toner prepared by depositing or fastening an additive to the surface of powder composed of at least a resin and a pigment is so formed that the value of the torque generated, when a conical rotor under rotation is penetrated 20 mm into the toner, under the conditions of a penetration rate 5 mm/min and a penetration speed ratio (=penetration speed/number of revolutions of the rotor) 1 to 10, after the toner has previously been put into a consolidated state in a sample container 16, becomes 1.0 to 3.3 mNm and the value of the load generated, when the rotor is penetrated 20 mm into the toner, becomes 0.3 to 0.78 N. PCOPYRIGHT: (C)2005,JPO&NCIPI

要解决的问题：通过使用流动性准确度高且不存在色差的评价，提供能够获得适当的点再现性和高图像质量而又不会造成可运输性问题且不会降低图像密度的调色剂。个体差异。

解决方案：通过将添加剂沉积或固定在至少由树脂和颜料组成的粉末表面上而制成的墨粉，形成为当旋转的圆锥形转子穿透20 mm时所产生的扭矩值在事先将调色剂置于样品容器中的固结状态之后，在渗透率为5 mm / min和渗透速度比（=渗透速度/转子的转数）为1到10的条件下，如图16所示，当转子穿入墨粉20毫米时，其值为1.0至3.3mNm，所产生的负载的值为0.3至0.78N。
