    Abstract: A lubricant applicator incorporated in a cleaning device disposed in an image forming apparatus having an image bearing member on which an image containing toner is formed, includes: a lubricant supplying unit that supplies lubricant; a brush roller that scrapes off the lubricant to apply the lubricant to a surface of the image bearing member; and a flicker member positioned on an upstream side from the lubricant supplying unit in a rotation direction of the brush roller, the flicker member coming into contact with the brush roller, wherein the flicker member is a plate-shaped member in which an opening is formed, the flicker member having elasticity to be allowed to elastically rock by coming into contact with the brush roller, and the opening is formed in a region with which the brush roller comes into contact.

    Abstract: A toner for electrostatic latent image development of the present invention includes toner particles containing toner mother particles and an external additive. The external additive contains fatty acid metal salt particles, and a volume based particle diameter (size) distribution of the fatty acid metal salt particles has two peaks on a side of smaller size and a side of larger size, respectively. A volume based mean particle diameter of the fatty acid metal salt particles having the peak on the side of smaller size is 3.0 μm or smaller and a volume based mean particle diameter of the fatty acid metal salt particles having the peak on the side of larger size is larger than a volume based mean particle diameter of the toner mother particles.

    Abstract translation: 本发明的静电潜像显影用调色剂包括含有调色剂母粒和外用添加剂的调色剂颗粒。 外部添加剂含有脂肪酸金属盐颗粒，脂肪酸金属盐颗粒的体积基础粒径（粒径）分布在较小尺寸和较大尺寸侧具有两个峰。 具有较小尺寸侧面的峰的脂肪酸金属盐粒子的体积平均粒径为3.0μm以下，脂肪酸金属盐粒子的体积平均粒径在较大尺寸侧具有峰值 大于调色剂母粒子的基于体积的平均粒径。
