摘要:
A substrate for electron source formation on which a plurality of electron-emitting devices are arranged, comprising a layer where SiO2 is made a main component on the substrate, wherein an etching rate of the SiO2 layer at room temperature in 0.4 wt % of hydrogen fluoride ammonium solution (NH4-HF2) is 150 nm/min or less reducing the time-dependent change of an electron emission characteristic of an electron-emitting device in low cost, sharply improving the increasing speed of a device current If and the uniformity of final arrival values of If sharply reducing the dispersion of the electron emission characteristic, and an electron source and an image-forming apparatus that each use-the substrate.

摘要:
The present invention provides a color image forming developer comprising yellow, magenta, and cyan toners each containing an infrared absorber, wherein the cyan toner has a maximum infrared absorbance in the infrared region lower than that of the magenta toner and that of the yellow toner, to simultaneously attain sufficient fixation capacity and sufficient resistance to void formation, and also provides an improved image forming method and an image forming device using the developer.
摘要:
The present invention discloses a yellow toner for flash fixation, comprising an infrared absorbent, one or more yellow colorants, and a binder resin, wherein a* of the infrared absorbent in an CIELAB color space is less than 0, and a* of one or more of the yellow colorants in the CIELAB color space is more than 0, or vice versa; and a developer and an image forming method using the yellow toner.
摘要:
The present invention provides a toner that contains release agent, does not cause contamination in an electrophotographic apparatus, and has environmental stability and charge stability. This release agent-containing toner includes a center portion that contains low-polarity release agent and pigment, and a surface layer formed by a resin phase that covers the center portion.
摘要:
A developing device for electrophotographic image has a developing mechanism having a developer carrier for carrying a developer along a preset circulating route including a developing area and a developer restricting element for restricting the developer on the developer carrier, and a developer supply mechanism having a storing unit. The storing unit is filled with a start-up developer in the vicinity of the developer carrier and a replenishing developer remoter than the start-up developer from the developer carrier. The start-up developer and the replenishing developer have different grain sizes or grain size distributions. Further, a developing method for electrophotograhic image has the steps of using the start-up developer at an initial state of use of the developing mechanism, and using the replenishing developer differed in grain size or grain size distribution from the start-up developer after an end of the initial state of use of the developing mechanism.
摘要:
A non-magnetic one-component developer is provided. This non-magnetic one-component developer includes toner particles and an external additive containing inorganic particles that adhere to the surface of each of the toner particles. In accordance with an emission analysis method utilizing fusion coupling plasma, the rate of free external additive that is determined by the ratio of the number of particles emitting light only from elements of the external additive to one toner particle is 9% or less by number. With such a non-magnetic one-component developer, the external additive will not be welded to the blade of a developing apparatus.
摘要:
A method for nonmagnetic monocomponent development is intended for use in an electrophotographic copying machine or electrophotographic printer and is capable of producing highly durable prints of high quality during continuous printing operations. In the nonmagnetic monocomponent development, a developer is transported by a development roller to a photoconductor drum. A Doctor blade triboelectrifies the developer and simultaneously regulates the thickness of a layer of the developer. As the developer, a toner is used, which toner is produced by coagulating minute particles having a diameter between 0.1 and 3.0 .mu.m and then heating the minute particles, thereby thermally fusing these particles.
摘要:
An antipenetrating agent is to be added to a solvent ink for preventing penetration of the solvent ink into a medium to be printed. The antipenetrating agent includes inorganic fine particles and a resin soluble in an organic solvent.
摘要:
A penetration inhibitor includes a rosin-series resin having weight-average molecular weight of at least about 16,000 and at most about 50,000. The penetration inhibitor is to be added to a solvent ink for an inkjet printer.
