Document Type and Number:
WIPO Patent Application WO/2014/123121
Kind Code:
A1
Abstract:
The problem is to provide a liquid developing agent obtained by coacervation and for electrophotography or electrostatic recording, wherein the liquid developing agent has good abrasion resistance. In order to solve the problem, provided is a liquid developing agent that is obtained by coacervation in which at least coloring resin particles formed from a pigment, a pigment dispersant, an acid group-containing resin, a binder resin, and a resin having a glass transition temperature of -120 to -60˚C are dispersed in an insulating liquid. The amount of the resin having a glass transition temperature of -120 to -60˚C contained in the coloring resin particles is 1.0 to 5.0 mass%.
