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 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： 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： A developing method, which comprises arranging a latent image-bearing member which bears a latent image on the surface and a toner-carrying member which carries an insulating non-magnetic toner at the developing section with a certain gap provided therebetween, coating the toner-carrying member with the insulating non-magnetic toner, conveying the resultant coated layer to the developing section while regulating the thickness thinner than said gap and developing the latent image on the latent image-bearing member under the application of an alternate electric field on the toner. Since the toner has a form of a microcapsule comprising a soft core material and a hard shell material and also contains a colorant in addition to the core material, adequate discharging can be effected during triboelectric charging to give an image with a constant density through stably charged state.

摘要： A developer is carried on a developer-carrying member and conveyed to a developing region to be used for developing an electrostatic latent image formed on an electrostatic latent image-bearing member. The developer includes a non-magnetic toner, and the toner includes toner particles containing 5-30 wt. % of a low-softening compound and having a shape factor SF-1 of 100-130. The developer-carrying member has a developer-carrying surface satisfying the conditions of: 0.2 .mu.m.ltoreq.Ra.ltoreq.5.0 .mu.m, 10 .mu.m.ltoreq.Sm.ltoreq.80 .mu.m, and 0.05 .ltoreq.Ra/Sm.ltoreq.0.5, wherein Ra denotes a center line-average roughness, and Sm denotes an average spacing between unevennesses. The toner shows good fixability and fluidity and is yet uniformly applied and conveyed to be used for developing because of the appropriate surface roughness of the developer-carrying member. The developed toner image can be transferred at a high transfer ratio.
