摘要： PROBLEM TO BE SOLVED: To provide the color image processor and color image forming system that generates an image recoding signal to obtain a print without generation of moire with a sufficient maximum density and excellent granularity so as to attain a high image quantity print. SOLUTION: A maximum black amount decision means 221 and a minimum black amount decision means 222 obtain a maximum black amount Kmax and a minimum black amount Kmin required to reproduce a color indicated by a 3-color signal received from a color image input device 100 and decide a setting black amount K, based on the maximum black amount Kmax and the minimum black amount Kmin. The maximum black amount Kmax and the minimum black amount Kmin are calculated, based on a maximum value and a minimum value of the black amount K being a variable in a function expression where colorimeter measurements of the received color image and the black amount K are related to color signals C, M, Y and the values of the C, M, Y satisfy relations of 0

摘要： PROBLEM TO BE SOLVED: To make formable an excellently photographic color image being free from glossiness irregularity or an edge difference in level, at a high speed, regardless of the dot area ratio of the input image, and make restrainable the consumption of of transparent particles. SOLUTION: In this image processing device, input RGB(red, green and blue) data are converted to YMCK data consisting of YMCK(yellow, magenta, cyan and black) data forming the toner image and T data forming the transparent particle image. In the image outputting device, the image holding material holding the toner image and the transparent particles image, and a recording medium provided with a thermoplastic transparent resin layer on the surface are held in close contact with there between, after melting the toner image, and the transparent particle image and the thermoplastic transparent resin layer, subsequently, to separate the recording medium together with the toner image and the transparent particles image from the image holding material. In the image processing device, based on the grand total of the maximum dot area ratio decided by the property of the image outputting and the dot area ratio of the YMCK data, the dot area ratio of the transparent particle image is made to the maximum value when the difference between the both is a specified value, and the dot area ration of the transparent particle image is made below the maximum value when the difference between the both exceeds a specified value.

摘要： PROBLEM TO BE SOLVED: To prevent reduced density at a rear end in contact with a background part of a medium tone part when the outputted image changes from the medium tone part to the background part in the subscanning direction without causing the large sized image forming device or image output device and a high cost. SOLUTION: An image processing section extracts a rear edge picture element in contact with a background part of a medium tone part when an image outputted from the image processing section receiving input image data Si changes from the medium tone part to the background part in the subscanning direction. A correction object picture element number (a) and a picture element correction amount (b) corresponding to a picture element value C are read from a lookup table based on the picture element value C of the rear edge picture element to correct the picture element value of the input image data Si and the output image data So after the correction are given to an image output section.

摘要： PURPOSE: To improve the reproducibility of dots and gathering of parallel lines in a low-density part, to improve the stability of circumstances for gradation and color reproducing, and to make it difficult; to recognize the hue change or the like due to the picture element position deviation or the like. CONSTITUTION: Picture density signal conversion means 405 and 406 having plural gradation reproducing characteristics different from each other are used and are operated at the timing synchronized with a picture density signal clock. These picture density signal conversion means are periodically selected by the select signal generated by a selecting means 404, and each selection period of this periodical selection is made longer than the period of the picture density signal clock, and the phase of the select signal is changed in every one or plural exposure scannings. Thus, not only a picture having a prescribed screen angle for each color as conventional is formed in a middle and high density part but also a picture to realize thinning of a low density part, which is impossible in a conventional device, and a prescribed screen angle is formed.

CONSTITUTION:This color image forming method consists of a latent image forming stage, developing stage, transferring and separating stage and fixing stage and comprises executing development in such a manner that the black toner images are formed in the lowermost layer by superposition of four colors of toner images i.e., three kinds of chromatic colors and black. The black toners consists of a resin component and a coloring agent and the resin component contains a polyester resin which does not contain a tetrahydrofurane-insoluble component. The mol.wt. measured by gerpermeation chromatography of the resin component has a weight average mol.wt. (Mw) of 25,000 to 80,000, a number average mol.wt. (Mn) of 2,000 to 10,000 and Mw/Mn>==10. The temp. at which the apparent melt viscosity of the black toner by a flow tester method attains 1X10 poise is in a range of 120 to 140 deg.C.

摘要： PURPOSE:To completely prevent irregularities in a color image from being formed due to potential unevenness caused by the roughness of the surface of a toner image in a preceding process by forming a beam spot in scanning direction on a photosensitive body in such a manner that the diameter of the beam spot determined by an image forming optical system is a predetermined times the pitch of picture element or more in the scanning direction. CONSTITUTION:Diameters of beam spots in a main and auxiliary scanning direction are set at 1.5 or more times larger than the pitch of picture elements in the main and auxiliary direction and charging, exposure, and development are applied a plurality of times to form images by means of toner of a plurality of colors on the body. Latent images on the photosensitie body formed by light beams is developed in wet or dry process using toner having particle diameter of 7mum or smaller using a developing unit 3. As a result, in a second color or succeeding colors, potential irregularities and caued by scatting of light at time of exposure generated due to the presence of toner a can be restrained and hence generation of irregularities in color or degradation of particles are restrained. Color developing liquid on the photosensitive body is collectively transferred to a record by a transfer corotron 4 and the liquid is passed through a fixing unit 7 and fixed so that a color image is formed. Thus a color image having good half tone can be obtained.
