Liquid developer

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.).

1. A liquid developer, comprising:
an insulating liquid; and toner particles dispersed in said insulating liquid, said insulating liquid having a flash point not lower than 100° C., said toner particles containing a resin, said resin containing 80 mass % or more of a first resin containing a polyester resin or a component derived from the polyester resin, wherein the component derived from the polyester resin is a portion of the first resin excluding a portion derived from an isocyanate group if the first resin is a urethane-modified polyester resin, and a solid content of said liquid developer corresponding to a portion of said liquid developer excluding said insulating liquid satisfying 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.).
