调色剂
摘要：
本发明提供一种在低温定影性和透明度方面优异并且具有高光泽度的调色剂，其在抗偏移性、贮存稳定性和显影稳定性方面优异。该调色剂特征在于：当调色剂在25℃溶于THF溶剂24小时时，四氢呋喃(THF)可溶性物质的GPC－RALLS－粘度计分析中在主峰峰顶处的惯性平方半径Rt为1.0nm至3.8nm；和该惯性平方半径Rt与惯性平方半径Rp满足Rt/Rp＜0.85的关系式，该惯性平方半径Rp为当具有绝对峰分子量值与调色剂主峰值相同的值的线性聚苯乙烯在25℃溶于THF溶剂24小时时，THF可溶物质的GPS－RALLS－粘度计分析中在主峰峰顶处的惯性平方半径。
摘要（英）：

The present invention provides a toner which is excellent in low-temperature fixability and transparency and has high gloss, and which is excellent in offset resistance, storage stability, and development stability. The toner is characterized in that: a square radius of inertia Rt at a peak top of a main peak in GPC-RALLS-viscometer analysis of tetrahydrofuran (THF) soluble matter when the toner is dissolved in a THF solvent at 25 DEG C for 24 hours is 1.0 nm to 3.8 nm; and the square radius of inertia Rt and a square radius of inertia Rp at a peak top of a main peak in GPC-RALLS-viscometer analysis of THF soluble matter when linear polystyrene, having an absolute peak molecular weight value at the same value as a main peak value of the toner, is dissolved in a THF solvent at 25 DEG C for 24 hours satisfy the relationship of Rt/Rp < 0.85.
