    摘要： There is disclosed here a class of liquid toner dispersions for developing electrophotographic images which give very high contrast half-tone dots with low contrast scanning light beams such as gaussian laser beams. The advantage of these toners is enhanced by the use of high electric field electrophoretic development conditions with high replenishment rate under which conditions rapid development to high image densities is obtained. This class of toners has toner particles of high mobility, low particle concentration in the dispersion, and a low fraction of its conductivity in the liquid milieu.

    摘要： in a conventional color electrophotographic method using a single transfer system, a color toner which cannot provide the highest image density until as many as four to six toner layers are superposed has been employed. Therefore, the color tone of a mixed color image formed by the superposition of toner images having different colors is likely to change or non-uniformity of color is likely to occur. The present invention uses a color toner only a single layer of which provides substantially the highest image density to eliminate the drawback described above to thereby make it possible to reproduce a mixed color image using a single transfer system. According to the present invention, a full color image having a gradation can be reproduced clearly.

    摘要： In an image forming apparatus for forming an ordinary copy or a tonality image for an original image for a printing master, original image data is divided into a predetermined area, and pixel density within the area is subjected to a density conversion in accordance with screen half-toning information which will increase density information toward the approximate center of these pixels, by way of example. The original image data or the density-converted image data is converted into a binary-coded signal conforming to the density, and an output image is formed in accordance therewith. Preferably, a specific mark is supperimposed on the output image.

    摘要： An image forming method of the present invention comprises: a first toner image formation process for forming a first toner image by forming, on a latent image carrier, a first latent image which corresponds to a first image and developing the first latent image by a first toner charged to one polarity through a development selected from normal and reverse developments so as to correspond to the polarity of the first toner; a second toner image formation process for forming a second toner image by forming, on the latent image carrier, a second latent image which corresponds to a second image and developing the second latent image by a second toner charged to the other polarity by the other development while applying a developing bias; and a transfer treatment process for simultaneously transferring said first and second toner images to a transfer medium; wherein said developing bias VB2 satisfies the following equations:
        |VT1 - VB2| > |VH2 - VB2|      (1)
        |VT1 - VB2| > |VT1 - VH2|      (2)
        where a surface potential of said first toner image is VT1, a background potential in said second toner image forming process is VH2, and the developing bias in said second toner image forming process is VB2.

    摘要： Disclosed is an electrophotographic liquid developer composition comprising a liquid medium, first toner particles able to be charged to one polarity and comprising a first dye and polymeric cores to which steric stabilizer polymers have been attached, second toner particles able to be charged to a polarity opposite to that of the first toner particles and comprising a second dye of a different color from that of the first dye and polymeric cores to which steric stabilizer polymers have been attached, and a charge director. The disclosed developer is suitable for developing electrostatic latent images in two different colors in a single development step. The latent image comprises three areas of charge; toner particles of one color are selectively attracted to one area, toner particles of the other color are selectively attracted to the second area, and the third area remains undeveloped as a background area.

    摘要： Four color toners of yellow, magenta, cyan and black, and four two-component developers containing the four color toners respectively in combination with a resin-coated ferrite carrier suitable for multi-color electrophotographic copying are provided. Each of the four-color toners is strictly regulated in relation not only to the carrier but also to the other color toners. More specifically, each color toner is strictly controlled with respect to a particle size distribution, freeness from agglomeration, melting characteristics including heat-absorption peaks and apparent viscosity on melting, chromaticity, triboelectric chargeability and optical toner concentration detection characteristic. Because of the strict regulation of these various parameters, the resultant multi-color toner or developer system shows excellent performances at every stage of multi-color electrophotography including development, transfer and fixing (color-mixing) for a long period of successive copying.
