摘要： The present invention is directed to a precise method of registering plurality of imaging stations (10,12,14,16), so as to form sequential images on a photoreceptor belt (18) in a single pass. A belt hole (23,24) is formed in the photoreceptor belt (18), outside the image area (I1-I4), but within the scan of the imager scan line. The scan line is sequentially swept in a transverse direction across the width of the belt (18). As the leading edge of the belt hole (23,24) advances into the sweeping beam, a plurality of beam sweeps will occur while the leading edge is moving through the sweep area. Due to the gaussian illumination of the scanning beam, the exposure at the belt edge gradually increases to a maximum point coinciding with the maximum illumination of the scanning beam. A detector (21,22) is placed beneath the belt (18) to provide a signal representing the exposure level of each scanning beam which crosses the leading edge of the advancing belt hole (23,24). The detectors (21,22) produce a current output representative of the exposure level. The current output is converted into voltage outputs which are then used in an extrapolation process to determine a midpoint for the illumination profile crossing the scan line and, from this, a reference time at which the midpoint of the beam illumination was reached. This reference time is then used to generate a precisely timed line sync signal which is reproducible through each of the imaging stations to produce registration of the first scan line of each image sequence with a very high degree of accuracy.

摘要： PURPOSE:To obtain a sharp image of high quality speedily by determining a positioning pattern during the formation of the 1st toner image and forming the 2nd toner image on the basis of the positioning pattern, and transferring plural toner images formed on an image carrier at a time. CONSTITUTION:Two reference marks 62 are added on an image carrier 21 at front ends of a blank part 61 in the running direction except at a hatched recording image part. Those are formed by writing them on the image carrier 212 during the 1st formation of an electrostatic latent image for yellow and developing them. Those reference marks 62 are detected by a detector 45 such as a photocoupler before following recording of, for example, magenta is performed to calculate a reference line L. Thus, recording positions of following colors, i.e. magenta and cyan are determined. Then, winding timing of data for magenta and cyan is synchronized according to the reference line. Consequently, registration of the respective colors is carried out by making respective images coincident with the image of the 1st color on the image carrier 21.

摘要： PURPOSE:To form good multicolor images by sticking a toner to the whole of an electrostatic latent image in a unit with one or more developing devices and sticking the toner to electrostatic latent image parts having a high surface potential with other developing devices if the electrostatic latent image should be developed in colors different from one another and has a difference of surface potential. CONSTITUTION:The reflected light from an original is reflected on scanning mirrors 8- 10 and passes a focusing lens 11 and is reflected on another mirror 12 and reaches a photosensitive body 1 to focus the original image. This electrostatic latent image consists of red, green, blue, and black latent images corresponding to colors of the picture on the original. Though a part of the light reaching the photosensitive body 1 is transmitted through a half mirror 14, the light reflected on the half mirror 14 passes another focusing lens 15 and reaches a color scanner 16. The original image is focused on the color scanner 16 to discriminate individual colors of the original picture. The output from a CCD17 is inputted to a CPU18, and the proportion of each color toner which should be stuck to an electrostatic latent image part corresponding to the color designating unit is operated by the CPU18, thereby improving the quality of reproduced multicolor images.

摘要： PURPOSE:To improve the granularity and color reproducibility of a polychromatic picture by providing the 2nd electrostatic charge process before a developing process after image exposure, and varying a leveling potential of each color between the white ground potential of an original and the potential of picture density to be reproduced. CONSTITUTION:The 2nd electrifier 3 is arranged between an image exposure station 2 and developing machines 4a-4c for three kinds of toner. When a DC constant voltage corotron is used as the 2nd electrifier 3, the leveling voltage VL is set between the potential VBG of the white ground part and the voltage Vn to be reproduced. Consequently, the potential of the white ground part rises up to V1 and the potential Vn of the density part rises up to Vn'. Namely, the unevenness of a surface potential pattern is leveled from a state shown by a broken line to a state shown by a solid line to reduce the intensity of a fringe electric field and also reduce the influence of edge effect, improving the granularity. Toner T is developed uniformly in proportion to the picture density to improve the color reproducibility.
