摘要:
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.

摘要:
The encapsulated toner for heat-and-pressure fixing of the present invention has 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. Moreover, the encapsulated toner has the following properties: 1) The glass transition temperature ascribed to the thermoplastic resin used as a main component of the heat-fusible core material is 10.degree. C. to 50.degree. C.; 2) A minimum load required for 58 compression of a particle size of the encapsulated toner is from 5 to 50 mgf, and a minimum load required for 10% compression of a particle size of the encapsulated toner is from 10 to 100 mgf, when a compressive variation of one toner particle is measured by a micro compression testing machine under the given conditions; and 3) The difference in cohesiveness before and after keeping the toner standing at 50.degree. C. for 24 hours, is not more than 10, wherein the cohesiveness is defined as the sum of values (a), (b), and (c) obtained by the following equations:(a)=(weight % of the toner remaining.times.1, on a 250 .mu.m mesh-sieve)(b)=(weight % of the toner remaining.times.0.6, and on a 149 .mu.m mesh-sieve)(c)=(weight % of the toner remaining.times.0.2, on a 74 .mu.m mesh-sieve)each of the weight % in the equations being measured by a powder property analyzer.
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.
