PROBLEM TO BE SOLVED: To provide a toner that utilizes characteristics when PHA resin being an ecological material is used for the toner, and reduces a change with time in performance due to crystallization of the PHA resin; and to provide the toner that can stably maintain an output image even under a high-temperature/high-humidity environment, and can obtain a high-quality output image.SOLUTION: A toner includes toner particles containing a polymer that includes a unit represented by the formula (1)(polyhydroxy alkanoic acid resin having a lateral chain modified with tricyclic diterpene).SELECTED DRAWING: None 【課題】 エコロジーな材料であるＰＨＡ樹脂をトナーに用いた場合の特性を活かしつつ、ＰＨＡ樹脂の結晶化による性能の経時的変化を抑えたトナーを提供することにある。また、出力された画像が高温／高湿環境下においても長期間にわたり安定して維持でき、高品質の出力画像が得られるトナーを提供する。【解決手段】 式（１）で示されるユニットを含む重合体（三環式ジテルペンにて側鎖を変性したポリヒドロキシアルカン酸樹脂）を含有するトナー粒子を有することを特徴とするトナー。【選択図】 なし
