Abstract: A developing method of the present invention has the steps of forming a uniform layer of a nonmagnetic one-component toner on a developer carrying sleeve with a developer blade; rotating an electrostatic latent image forming member and the developer carrying sleeve; and applying the toner on the developer carrying sleeve onto an electrostatic latent image formed on the electrostatic latent image forming member. The toner used herein is an encapsulated toner having a heat-fusible core material and a shell formed thereon. By using this development for a nonmagnetic one-component toner of the present invention, clear images free from background can be stably formed for a large number of copying.

Abstract: The present invention is directed to an encapsulated toner for heat-and-pressure fixing having 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. An amorphous polyester is used as the main component of the shell, and the amount of the amorphous polyester is preferably 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 heated roller.

Abstract: The present invention is directed to a developing method of a magnetic encapsulated toner, which can be fixed even at a nip pressure of 0.01 to 0.1 kg/cm without a supply of silicone oil onto a surface of a heat roller, using a toner projection developing device. The fixing in the present invention is carried out at a temperature of not more than 120 DEG C and at a nip pressure of 0.01 to 4 kg/cm. By using these methods, the miniaturization of the overall apparatus can be achieved.

Abstract: The present invention is directed to an encapsulated toner for heat-and-pressure fixing, which has a heat-fusible core material containing at least a coloring agent and a shell formed thereon so as to cover the surface of the core material. The core material includes a thermoplastic resin as its main components produced by a polymerization reaction, at the time of encapsulation, of 0.05 to 20 parts by weight of the (A) alpha , beta -ethylenic copolymerizable monomer having an acid anhydride group and 99.95 to 80 parts by weight of the (B) other alpha , beta -ethylenic copolymerizable monomer. Alternatively, the core material contains a copolymer having one or more acid anhydride groups added as one component of the core material resin-constituting material at the time of encapsulation.
