Toner
摘要：
Provided is toner which is excellent in developing property, transferring property, and fixing property, hardly affected by its surrounding, and has good endurance. The toner has a peak temperature of maximum endothermic peak in the range of 60 to 100° C. in an endothermic curve of differential scanning calorimetry (DSC) measurement; silica particles in the toner contain a titanium element; and the silica particles satisfy the following expressions. 0.7≦(Ia1/Ib1)≦2.0 0.7≦(Ia2/Ib2)≦2.0 where Ia1 represents a maximum intensity in the case of 2θ=25.3 deg, Ib1 represents a mean intensity in the cases of 2θ=25.3 deg+2.0 deg. and of 2θ=25.3 deg.−2.0 deg., Ia2 represents a maximum intensity in the case of 2θ=27.5 deg and Ib2 represents a mean intensity in the cases of 2θ=27.5. deg+2.0 deg. and of 2θ=27.5 deg.−2.0 deg.
摘要（中）：

提供显影性，转印性和定影性优异的调色剂，几乎不受其周围的影响，并且具有良好的耐久性。 调色剂在差示扫描量热法（DSC）测量的吸热曲线中具有在60至100℃范围内的最大吸热峰的峰值温度; 调色剂中的二氧化硅颗粒含有钛元素; 二氧化硅粒子满足下式。 <？in-line-formula description =“In-line Formulas”end =“lead”？> 0.7 <=（Ia <1> / Ib ）<= 2.0 < ？in-line-formula description =“In-line Formulas”end =“tail”？> <？in-line-formula description =“In-line formula”end =“lead”？> 0.7 <=（Ia <= 2.0 <？in-line-formula description =“In-line Formulas”end =“tail” 在2θ= 25.3度的情况下，SUB>表示最大强度，Ib 2表示在2θ= 25.3°+ 2.0°的情况下的平均强度。 在2θ= 27.5°的情况下，Ia 2表示最大强度，而在2θ= 27.5°的情况下，Ib 2表示在这些情况下的平均强度 的2theta = 27.5。 deg + 2.0度 并且2θ= 27.5°-2.0°。
