调色剂用外部添加剂、调色剂用外部添加剂的制造方法、和调色剂
摘要：
本发明涉及调色剂用外部添加剂、调色剂用外部添加剂的制造方法、和调色剂。一种调色剂用外部添加剂，其具有包含结晶性树脂的树脂细颗粒和嵌入树脂细颗粒中的无机细颗粒，其中无机细颗粒的一部分在树脂细颗粒的表面上露出，并且在调色剂用外部添加剂的差示扫描量热测定中，在第一次升温期间的最大吸热峰温度T1(℃)和在第一次降温期间的最大放热峰温度T2(℃)满足下式(1)至(3)，其中在第一次升温期间以10℃/min的升温速度在-40℃和150℃之间进行测量，和在第一次降温期间以10℃/min的降温速度在150℃和-40℃之间进行测量：T1-T2≤40.0        (1)50.0≤T1≤120.0        (2)10.0≤T2≤80.0         (3)。
摘要（英）：

The invention relates to an external additive for a toner, a method for producing the external additive for the toner, and the toner. The external additive for the toner comprises resin fine particlescontaining a crystalline resin and inorganic fine particles embedded in the resin fine particles, wherein a portion of the inorganic fine particles are exposed on a surface of the resin fine particles; in the differential scanning calorimetry measurement of the external additive for the toner, the maximum endothermic peak temperature T1 (DEG C) during a first temperature rise and the maximum exothermic peak temperature T2 (DEG C) during a first temperature drop satisfy the following formulae (1) to (3): wherein the measurement is done between 40 DEG C and 150 DEG C at a temperature rise rateof 10 DEG C/min during the first temperature rise, and the measurement is done between 150 DEG C and 40 DEG C at a temperature drop rate of 10 DEG C/min in the first temperature drop; the formulas are: 1, T1-T2<=40.0; 2, 50.0<=T1<=120.0; 3, 10.0<=T2<=80.0.
