Summary:To provide a liquid developer having high volume resistivity and excellent dispersion stability and a manufacturing method of the liquid developer.SOLUTION: A liquid developer contains a carrier liquid and toner particles insoluble in the carrier liquid. Specific partial structures are bound on surfaces of the toner particles by covalent binding. A manufacturing method of the liquid developer includes a process (I) of covalently binding compounds having the specific partial structures on the surfaces of the toner particles.SELECTED DRAWING: None 【課題】体積抵抗率が高く、分散安定性に優れた液体現像剤、および、体積抵抗率が高く、分散安定性に優れた液体現像剤の製造方法を提供する。【解決手段】キャリア液体と、キャリア液体に不溶なトナー粒子と、を含有する液体現像剤であって、特定の部分構造が、トナー粒子の表面に、共有結合を介して結合している液体現像剤、および、キャリア液体と、キャリア液体に不溶なトナー粒子と、を含有する液体現像剤の製造方法であって、特定の部分構造を有する化合物を、トナー粒子の表面に共有結合させる工程（Ｉ）を含む、液体現像剤の製造方法。【選択図】なし
