Abstract: A liquid developer includes an insulating liquid and toner particles which are dispersed in the insulating liquid and contain a resin and a coloring agent. The resin contains a first resin which is a crystalline urethane-modified polyester resin resulting from increase in chain length of a component derived from a polyester resin by a compound containing an isocyanate group. The toner particles have a peak in a DSC curve in temperature increase at 55° C. or higher, have a peak in the DSC curve in temperature decrease at 30° C. or higher, and have a storage elastic modulus at 80° C., not lower than 1×105 Pa and not higher than 1×107 Pa.

Abstract: A liquid developer is obtained by dispersing toner particles containing a core resin, a shell resin different from the core resin, and a coloring agent in an insulating liquid. The core resin contains a crystalline urethane-modified polyester resin. A solid content of the liquid developer corresponding to a portion of the liquid developer excluding the insulating liquid has a storage elastic modulus at 80° C., not lower than 1×104 Pa and not higher than 5×106 Pa. A lowest temperature at the time when an absolute value of an amount of change in a logarithmic value (log(G′)) of a storage elastic modulus (G′) of the solid content of the liquid developer with respect to a temperature T (° C.) (|Δ log(G′)/ΔT|) satisfies an Equation (1) below is not lower than 45° C.: |Δ log(G′)/ΔT|>0.1 Equation (1).
