    • 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).
    • 提供一种树脂颗粒的非水分散体,其中树脂颗粒具有均匀的粒径和形状,并且表现出优异的定影性,特别是当用作液体电子照相显影剂时。 更具体地说,提供了在20℃下相对介电常数为1〜4的不亲水性有机溶剂(L)中分散有树脂粒子(C)的非水分散体(X),树脂粒子(C)为 核壳型树脂颗粒各自包含含有树脂(b)的树脂颗粒(B)和含有树脂(a)的细颗粒(A),并且粘附到树脂颗粒(B)的表面上, 或在树脂颗粒(B)的表面上形成膜,其中(a)在(L)中在25℃下的溶解度相对于(a)的重量为10重量%以下。
