Abstract
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.).
Claims5
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 component derived from a 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.).
