摘要： A liquid developer in which toner particles are dispersed in an insulating liquid, the toner particles having such a core-shell structure that shell particles containing a shell resin are attached to or cover surfaces of core particles containing a core resin, the core resin having an acid group and an acid dissociation constant not smaller than 2.90 and not greater than 8.00, and a method for manufacturing the same are provided. The toner particles can have a volume average particle size not smaller than 0.01 μm and not greater than 100 μm and a coefficient of variation of volume distribution not lower than 1% and not higher than 100%. This liquid developer has excellent fixability which allows adaptation to various recording materials, can be fixed in a wide temperature range, and is extremely low in deterioration in fixability during storage.
