Description

本発明は、重合性単量体、着色剤、水酸基含有スチレン系樹脂を含有する重合性単量体組成物を水系媒体中に加え、該水系媒体中で該重合性単量体組成物の粒子を形成し、該重合性単量体組成物の該粒子に含まれる該重合性単量体を重合させることにより得られるトナー粒子を含有するトナーであって、
該着色剤が、ロジンを５質量％以上３０質量％以下の量含有しており、
トルエンに溶解させた該ロジンの懸滴法による水に対する界面張力をα（ｍＮ／ｍ）としたとき、該αが、２０以上２８以下であり、
トルエンに溶解させた該水酸基含有スチレン系樹脂の懸滴法による水に対する界面張力をβ（ｍＮ／ｍ）としたとき、該βが、２０以上３３以下である
ことを特徴とするトナーに関する。 The present invention is a polymerizable monomer, the colorant, the particles of the polymerizable monomer composition having containing a hydroxyl group-containing styrene resin was added in an aqueous medium, the polymerizable monomer composition in aqueous medium is formed and a toner containing toner particles obtained by Rukoto by polymerizing the polymerizable monomer contained in the particles of the polymerizable monomer composition,
Coloring agent, and contains an amount of 5 mass% to 30 mass% of rosin,
When the interfacial tension α (mN / m) to water by the hanging drop method of the rosin was dissolved in toluene, the alpha is, is 20 or more 28 or less,
When the interfacial tension against water by the hanging drop method of the hydroxyl group-containing styrene-based resin dissolved in toluene β and (mN / m), the β is a toner which is characterized in that 20 or more 33 or less.
