Nonaqueous dispersion of resin particles

摘要

Provided is a nonaqueous dispersion of resin particles, in which the resin particles have uniform particle diameters and shapes and which exhibits excellent fixing properties, particularly when used as a liquid electrophotographic developer. More specifically, provided is a nonaqueous dispersion (X) in which resin particles (C) are dispersed in a nonhydrophilic organic solvent (L) that exhibits a relative permittivity of 1 to 4 at 20° C., the resin particles (C) being core-shell type resin particles each of which comprise a resin particle (B) that contains a resin (b) and fine particles (A) that contain a resin (a) and that either adhere to the surface of the resin particle (B) or form a film on the surface of the resin particle (B), wherein the solubility of (a) in (L) at 25° C. is 10 wt % or less relative to the weight of (a).
