ABSTRACT:
A liquid toner for electrophotography and a method of preparing the liquid toner are disclosed. The liquid toner includes a carrier liquid, an organosol, a colorant, a charge controlling agent (CCA), and (meth)acrylic (co)polymer soluble in the carrier liquid. The liquid toner has a low solidification rate and good redispersion when left for a long period of time, especially at a high temperature for a long period of time, while maintaining the existing physical properties of a liquid toner, such as image density, at certain levels.
