Summary:PROBLEM TO BE SOLVED: To provide a curable liquid developer which provides high image density, is less likely to cause image blur, and exhibits sufficient fixability.SOLUTION: A curable liquid developer contains a radical polymerizable liquid monomer, photopolymerization initiator, toner particles insoluble in the radical polymerizable liquid monomer, and an amine compound. The amine compound contains an amino group and at least one group selected from a group consisting of an alkyl group having a carbon number of 6 or greater, cycloalkyl group having a carbon number of 6 or greater, alkylene group having a carbon number of 6 or greater, and cycloalkylene group having a carbon number of 6 or greater. The amine compound has an amine value within a range of 2 to 200 mgKOH/g, inclusive.SELECTED DRAWING: None 【課題】高い画像濃度が得られるとともに画像ボケを生じにくく、十分な定着性を有する硬化型液体現像剤を提供すること。【解決手段】ラジカル重合性液状モノマー、光重合開始剤、該ラジカル重合性液状モノマーに不溶なトナー粒子、及びアミン化合物を含有する硬化型液体現像剤であって、アミン化合物が、アミノ基、並びに、炭素数６以上のアルキル基、炭素数６以上のシクロアルキル基、炭素数６以上のアルキレン基及び炭素数６以上のシクロアルキレン基からなる群より選ばれた少なくとも一つの基を含有し、アミン化合物のアミン価が、２ｍｇＫＯＨ／ｇ以上２００ｍｇＫＯＨ／ｇ以下であることを特徴とする硬化型液体現像剤。【選択図】なし
