| Zusammenfassung: | A liquid developer containing toner particles containing a resin containing a polyester and a pigment, wherein the toner particles are dispersed in an insulating liquid in the presence of a dispersant,
wherein the insulating liquid has a boiling point of 300°C or lower, and wherein the insulating liquid has a peak intensity ratio of a methyl group calculated by the formula (1): Peak Intensity Ratio % of Methyl Groups = A A + B × 100 wherein A is a peak intensity ascribed to CH 3 stretching vibration when measured with a Fourier transform infrared spectrometer, B is a total peak intensity ascribed to CH 2 stretching vibration and CH stretching vibration, of 25% or more, or wherein the insulating liquid contains a polyisobutene. |
