摘要： A liquid developer is obtained by dispersing toner particles containing at least a resin and a coloring agent in an insulating liquid. The toner particles have a core-shell structure that first resin particles containing a first resin are attached to or cover surfaces of second resin particles containing a second resin. The coloring agent contains nigrosine. A content of nigrosine in the toner particles is not lower than 1 mass % and not higher than 20 mass %. The second resin satisfies Equations (1) to (2) below. In Equations (1) to (2), x represents a number average molecular weight of the second resin and y represents a urethane group concentration (mass %) in the second resin. −0.00003x+2.03≦y≦−0.00003x+6.95 Equation (1) 10000≦x≦60000 Equation (2)

摘要： A liquid developer includes an insulating liquid and toner particles dispersed in the insulating liquid. The insulating liquid has a flash point not lower than 100° C. The toner particles contain a resin, and the resin contains 80 mass % or more of a first resin containing a component derived from a polyester resin. A solid content of the liquid developer corresponding to a portion of the liquid developer excluding the insulating liquid satisfies relation of G′(T0)/G′(T0+10)≧10 (50° C.≦T0≦70° C.), where G′(T0) represents a storage elastic modulus at a temperature T0 (° C.) and G′(T0+10) represents a storage elastic modulus at a temperature (T0+10) (° C.).
