    摘要: A double-tone printer includes an image scanner which inputs an image signal representing an original. The image signal is converted into a density signal according to a density correction curve for a light color and a stencil master making signal for the light color is made by binary-coding the density signal. Further the image signal is converted into a density signal according to a density correction curve for a dark color and a stencil master making signal for the dark color is made by binary-coding the density signal components. Images of the respective stencil masters made on the basis of the stencil master making signals for the light color and the dark color are printed on a printing paper in light color ink and dark color ink so that the printed images in the respective color inks overlap each other. The density correction curve for the light color gives a print density which increases with increase in the value of the image signal in a first range where the value of the image signal is lower than a threshold value and is a fixed maximum print density in a second range where the value of the image signal is not lower than the threshold value, and the density correction curve for the dark color gives a print density which is a fixed minimum print density in the first range and increases with increase in the value of the image signal in the second range.

    摘要: When image forming is repeated with cleanerless image forming apparatus, “positive ghost”, which means that a preceding image is slightly left, occurs because a residual toner is not recovered by a developer. Even if an image forming apparatus with an electrically conductive brush or auxiliary device repeats image forming or continuously forms an image with a high image ratio, resistance of the brush increases because the residual toner is deposited on the electrically conductive brush. As a result, advantages of the electrically conductive brush which erases traces of the preceding image are lost. Therefore, in accordance with this invention there are provided an image forming apparatus which does not let image traces leave, and an image forming apparatus which prevents (or reduces) the resistance of auxiliary devices and cleans auxiliary devices.

    摘要: In an image thickening processing method, a thickening processing is carried out on a binary image made up of black picture elements and white picture elements, which are adjacent to one another along vertical and horizontal directions. Each of the black picture elements is set as a black picture element of interest. A vertically adjacent picture element, which is adjacent to the black picture element of interest along a single vertical direction, and a horizontally adjacent picture element, which is adjacent to the black picture element of interest along a single horizontal direction, are detected. Also, an obliquely adjacent picture element, which is adjacent to all of the black picture element of interest, the vertically adjacent picture element, and the horizontally adjacent picture element, is detected. Each of the thus detected three adjacent picture elements is set as a black picture element only in cases where each of the thus detected three adjacent picture elements does not belong to a region, which is surrounded by a plurality of black picture elements and is to be recorded as a blank.
