摘要： PURPOSE: A dry toner is provided to prevent the sticking to members of a fixing device regardless of the configuration of the fixing device, obtain stable high image quality even when the toner is used under high humidity or low humidity condition, and prevent image defects with time. CONSTITUTION: In the dry toner having toner particles containing at least a binder resin and magnetic iron oxide, particles containing liberated iron elements exist by 100 to 350 pieces per 10,000 toner particles. The weight average particle size of the toner is 5 μm to 12 μm. In particles longer than 3 μm particle size contains such particles more than 90%, by number, more than 0.90 circularity(a) calculated by formula: a=L0/L, wherein L0 is the circumference length of a circle having the same projected area as that of the particle image and L is the circumference length of the particle image. The cut rate Z and the weight average particle size X of the toner, and the cumulative value Y of the particles more than 0.950 circularity, by number, and the toner weight average particle size X satisfy specified relations.
摘要翻译：目的：提供干式调色剂，以防止固定装置的构件粘附，无论定影装置的结构如何，即使在高湿度或低湿度条件下使用调色剂，也能获得稳定的高图像质量，并防止图像缺陷时间。构成：在具有至少含有粘合剂树脂和磁性氧化铁的调色剂颗粒的干燥调色剂中，含有释放铁元素的颗粒每10,000个调色剂颗粒存在100至350个样品。调色剂的重量平均粒径为5μm〜12μm。在超过3μm的颗粒尺寸的颗粒中，包含大于90％的颗粒，数量大于0.90，圆形度（a）由以下公式计算：a = L0 / L，其中L0是具有相同投影面积的圆的圆周长度与粒子图像的长度相同，L是粒子图像的周长。调色剂的切割速度Z和重均粒径X以及大于0.950圆形度的颗粒的累积值Y和数量和调色剂重均粒径X满足规定的关系。
