    摘要: According to a toner and a manufacturing method of the present invention, the toner, which is composed of a binding resin component precipitated in particle shapes with a coloring agent component dispersed in the binding resin component, is produced by dissolving the binding resin component in a supercritical fluid (a SCF), blending the coloring agent component in the SCF, and lowering solubility of the binding resin component for precipitating the binding resin component in the particle shapes. Even when the coloring agent content is increased, by the SCF, the toner can maintain dispersibility of the coloring agent component in the binding resin component precipitated in the particle shapes, meanwhile coloring power is also maintained thereby. Therefore, the toner can promote miniaturization of an image forming apparatus using the toner.

    摘要: An electron emitting element includes an electrode substrate, a thin-film electrode, and an electron acceleration layer provided between them. The electron acceleration layer includes a fine particle layer containing insulating fine particles, which is provided on a side of the electrode substrate, and a deposition of conductive fine particles, which is provided on a surface of the fine particle layer. In the electron acceleration layer, a conductive path is formed in advance, and the deposition has a physical recess which is an exit of the conductive path and which serves as an electron emitting section. Electrons are emitted via the electron emitting section. With the arrangement, it is possible to realize an electron emitting element which prevents that an electrode on an electron emission side gradually wears off along with electron emission and which can maintain an electron emission characteristic for a long period.
