Abstract
There is provided a liquid developer containing a toner that has a ratio G′(65)/G′(90) of a storage modulus G′(65) at 65° C. to a storage modulus G′(90) at 90° C. of from 1×10 to 1×103, and a carrier liquid that has a difference ΔSP(tc) of SP value between the carrier liquid and the toner of from 1.5 to 7.0, and an image forming apparatus containing an electrostatic latent image holding member, a charging device, a latent image forming device, a developing device, a transfer device and a fixing device.

A liquid developer containing:
- a toner that has a ratio G′ (65)/G′(90) of a storage modulus G′ (65) at 65° C. to a storage modulus G′ (90) at 90° C. of from 1×10 to 5×102, and
- a carrier liquid that has a difference of solubility parameter (SP) value between the carrier liquid and the toner (ΔSP(tc)) of from 1.5 to 7.0, wherein SP is the square root of density of cohesive energy.
