PROBLEM TO BE SOLVED: To provide a liquid developer in which even when an apparatus is opened for maintenance, the liquid developer remaining in the apparatus is less likely to be cured by visible light, and the liquid developer exhibits sufficient fixability by ultraviolet irradiation.SOLUTION: In an ultraviolet-curable liquid developer comprising toner particles, polymerization initiator, sensitizer, and polymerizable monomer, the sensitizer includes a compound represented by X-Y (X is a triphenylenyl group or the like, and Y is a triphenylenyl group or the like).SELECTED DRAWING: None 【課題】メンテナンス等で装置を開放した場合には装置内に残った液体現像剤が可視光で硬化しにくく、かつ紫外線照射により十分な定着性を示す液体現像剤を提供すること。【解決手段】トナー粒子、重合開始剤、増感剤、および、重合性モノマーを含む紫外線硬化型液体現像剤において、増感剤が、Ｘ−Ｙ（Ｘはトリフェニレニル基など、Ｙはトリフェニレニル基など）で示される化合物を含む。【選択図】なし
