Toner for developing electrostatic charge image, electrostatic charge image developer, toner cartridge, process cartridge and image forming apparatus
摘要：
The invention provides a toner for developing an electrostatic image including toner particles having a shape factor SF1 of 110 or more and including a binder resin, and particles of an external additive that adhere to the toner particles, wherein the particles of the external additive including first particles, and second particles which are adhered to the first particles and have a primary particle size of 0.2 times to 0.5 times as large as that of the first particles, and in an image obtained by observing the particles of the external additive with a microscope, when the projection surface area of the first particle is defined as S1 and the total of the projection surface areas of the second particles which are not hidden by the first particle is defined as S2, S2 being from 0.1 times to 0.5 times as large as S1.
摘要（中）：

本发明提供了一种用于显影静电图像的调色剂，其包括形状系数SF1为110或更大的调色剂颗粒，并且包括粘合剂树脂，以及附着在调色剂颗粒上的外部添加剂颗粒，其中外部添加剂的颗粒包括第一 颗粒和第二颗粒，其粘附到第一颗粒上并且具有一次粒径为第一颗粒的一次粒径的0.2倍至0.5倍，并且在通过用显微镜观察外部添加剂的颗粒而获得的图像中， 当第一颗粒的投影表面积被定义为S1，并且未被第一颗粒隐藏的第二颗粒的​​投影表面积的总和定义为S2时，S2为S1的0.1倍至0.5倍 。
