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。

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 printer head capable of increasing intensity of dot-like light irradiated onto a record medium without requiring to increase a drive voltage or the number of printer heads arranged. The optical printer head includes a luminous element including two luminous dot arrays arranged in parallel to each other at a predetermined interval in a sub-scanning direction. The luminous dot arrays each are constituted of a plurality of luminous dots which have a dimension in the sub-scanning direction increased by a predetermined magnification as compared with that in a main scanning direction and are spaced from each other at identical intervals in the main scanning direction. The luminous dots of the two luminous dot arrays are arranged in an offset manner while being deviated from each other in the main scanning direction by a distance equal to the dimension thereof in the main scanning direction. Also, a reduction optical system is arranged for carrying out irradiation of light emitted from the luminous dots while reducing a dimension of the light in the sub-scanning direction by a reciprocal of the predetermined magnification.

摘要： An image forming apparatus, comprises an electrostatic image-bearing member for holding an electrostatic charge image and a toner-carrying member having a surface for carrying a magnetic toner thereon, wherein the surface of the toner-carrying member has an unevenness comprising sphere-traced concavities formed by blasting with particles with a definite spherical shape; the magnetic toner comprisaes 17-60% by number of particles of 5 microns or smaller, 1-23% by number of particles of 8-12.7 microns, and 2.0% by volume or less of particles of 16 microns or larger and has a volume-average particle size of 4-11 microns; the electrostatic image-bearing member and the toner-carrying member are disposed with a prescribed gap therebetween at a developing station; means for forming a magnetic toner layer on the toner-carrying member in a thickness which is thinner than the prescribed gap; and means for applying an alternating electric field for development with the magnetic toner at the developing station. The surface of the toner-carrying member comprising the sphere-traced concavities allows the forming of a uniform thin toner layer thereon when combined with the magnetic toner having a specific particle size distribution while the soiling of the surface is prevented for a long period of use.
