摘要： A heat fixable toner comprises a binder resin and a release agent. The binder resin comprises a polyester resin, and the release agent comprises a graft-modified polyolefin. A recording medium containing a toner image of said heat fixable toner is heat-fixed by contacting the recording medium with a heater element through a film interposed therebetween. After the heat-fixing step, the film is peeled from the fixed toner image while the film surface temperature is higher than the endothermic peak temperature of the toner.

摘要： A method of heat-fixing a visible image of toner to a recording medium comprises applying a toner image onto the recording medium, whereinthe toner to form said toner image or the resin component of the toner has the properties such that the melt viscosity .eta.' measured by an overhead-type flow tester is from 10.sup.3 to 10.sup.6 poise at a temperature within the temperature range of from 120.degree. C. to 150.degree. C., and the absolute value of the inclination of a graph is not more than 0.50 ln (poise)/.degree.C. when the natural logarithms ln.eta. of the melt viscosities at 120.degree. C. and 150.degree. C. are plotted with respect to the temperatures; and heat-fixing the toner image retained on the recording medium to the recording medium by use of a heater element as stationarily supported and a pressure member that brings said recording medium into close contact with said heater element through a film interposed between them.

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： 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.
