摘要： An encapsulated toner for development of electrical latent images comprises a core particle containing a colorant and a soft solid material, inorganic fine particles attached to the vicinity of the surface of the core particle, and a shell coating the core particle and the inorganic fine particles. The inorganic fine particles function to, e.g., reinforce the encapsulated toner with a thin shell and may be attached to the core particles through dry-mixing. The core particles with the attached inorganic particles may be coated with a shell resin through phase separation.

摘要： A mixture of a colorant, and a binder compound having an aliphatic hydrocarbon long chain and having a relatively low melt viscosity, is kneaded in a molten state in the presence of solid media such as balls or beads to form a uniform mixture in which the colorant particles or aggregates have been disintegrated to a size of 5 .mu. or below. Solid particles which may be used as a toner are formed from the uniform mixture and may be encapsulated, as desired, to provide a capsule toner.

摘要： An encapsulated toner is provided by coating core particles with an outer shell. The outer shell comprises, as predominant components thereof, vinyl polymers A and B of different molecular weights. More specifically, the ratio of the number-average molecular weight of the vinyl polymer A (Mn.sub.A) to that of the vinyl polymer B (Mn.sub.B) is in the range of 2 to 15. The vinyl polymers A and B respectively have a ratio of weight-average molecular weight to number-average molecular weight of 5 or less. Because of these specific molecular weight characteristics of the shell-constituting polymers, the durability and triboelectric charging characteristics of the encapsulated toner are improved. These effects are enhanced particularly when inorganic fine particles are attached to embedded in the surface or surface layer of the core particles.
摘要翻译：通过用外壳涂覆芯颗粒来提供包封的调色剂。作为其主要成分的外壳包含不同分子量的乙烯基聚合物A和B. 更具体地说，乙烯基聚合物A（MnA）与乙烯基聚合物B（MnB）的数均分子量的比例在2至15的范围内。乙烯基聚合物A和B的比例分别为重均分子量与数均分子量为5以下。由于构成壳的聚合物的这些特定的分子量特性，胶囊化调色剂的耐久性和摩擦带电特性得到改善。这些效果特别是当无机细颗粒附着在嵌入在核心颗粒的表面或表面层中时。
