An amorphous polyester is used as the main component of the shell, and the amount of the amorphous polyester is normally 3 to 50 parts by weight, based on 100 parts by weight of the core material. The encapsulated toner of the present invention is excellent in offset resistance, fixable even at a low temperature and excellent in blocking resistance when it is used for heat-and-pressure fixing using a heat roller.

摘要： The present invention is directed to an encapsulated toner for heat-and-pressure fixing whose shell contains a copolymer having one or more acid anhydride groups as the main component. The encapsulated toner of the present invention has excellent offset resistance and fixing ability even at a low fixing temperature, and also it is excellent in blocking resistance. Further, since the resin having a negative charge is used as a shell material, clear images free from background contamination can be stably formed for a large number of copying.

摘要： The encapsulated toner for heat-and-pressure fixing which includes a heat-fusible core material containing at least a thermoplastic resin and a coloring agent, and a shell formed thereon so as to cover the surface of the core material is produced by a process having the step of carrying out in situ polymerization using a thermoplastic resin as a main component of the shell to form a shell having a structure in which a part of the heat-fusible core material is incorporated therein, the thermoplastic resin having a mechanical loss tangent (tan .delta.) in the range of from 1.0 to 20.0 based on a dynamic viscoelasticity, when measured with a sine stress having an angular frequency of 25 rad/s at a temperature of from 80.degree. to 120.degree. C. By using the encapsulated toner, good offset resistance can be obtained in the resulting toner even when its fixing speed is slow. Also, the core material is likely to be released from the encapsulated toner upon fixing while retaining good blocking resistance and good shocking resistance.

摘要： A method of forming fixed images includes charging a photoconductor; exposing the photoconductor to light; developing an electrostatic latent image, such that a toner is applied to the electrostatic latent image formed on a transfer film moving in partially close contact with the photoconductor to form a visible image; transferring the formed visible image onto a recording medium such as a recording paper; and fixing the transferred visible image onto the recording medium. The toner is an encapsulated toner, the photoconductor is a heat-resistant photoconductor, and the transfer process and the fixing process are simultaneously carried out on the surface of the heat-resistant photoconductor covered with the transfer film onto the preheated recording medium.

摘要： A capsulated toner for heat pressure fixation comprising a heat-meltable core material and an outer shell, said core material containing a colorant and a thermoplastic resin as a major constituent, produced by copolymerizing (A) an .alpha.,.beta.-ethylenically copolymerizable monomer having an amino group and (B) .alpha.,.beta.-ethylenically copolymerizable monomer other than (A), said outer shell being provided so as to cover the surface of the core material. When the capsulated toner of the present invention is used, the dependency of the amount of electrification upon the environment is small because the electrification can be regulated from within the capsulated toner. Further, because the offset resistance in a heat pressure fixation system, such as a heat roller, is excellent, the fixation can be conducted at a low temperature. Further, the blocking resistance is so good that a clear image, free from fogging, can be stably formed over a plurality of uses.
