    摘要: An image forming apparatus includes an image holding member for forming a toner image, and a transfer roller for transferring the toner image formed on the image holding member onto a recording paper sheet. The absolute value of (.DELTA. log R)/.DELTA.V[(log .OMEGA.)/kV] representing the voltage dependence of resistance R of the transfer roller is set not more than 0.5. The contacting portion of the transfer roller and an intermediate belt can be uniformly discharged, and therefore intermediate belt can be prevented from being changed in its property. As a result, an image forming apparatus having a stable transfer characteristic can be provided.

    摘要: An actuator has a frame and a slider body which are both made of extruded shapes of light-metal alloy. A first rail member is fastened to the frame by means of a simple construction. An upper sealing member is placed between the frame and the slider body. With the actuator constructed as stated earlier, the frame is an elongated extrusion of U-shape in transverse section whose side walls have first recesses of dovetail configuration to fit over first rail members and flanges. A slider has therein the slider body having second recesses of rectangular shape to fit over second rail members. There is further provided a driving unit to force the slider with respect to the frame. The first rail members each have the wedged configuration including tapered contours and dents, while the second rail members each have the rectangular shape.

    摘要: Differing ratios of the amount of light from light source LD2 to the amount of light from light source LD1 are provided. An image pattern for adjustment that includes, for each color, an area made up of isolated dots by light source LD1 and an area made up of isolated dots by light source LD2, is printed for each ratio. In a copier, a density of each area is detected, a ratio at which a difference between the density of an area of isolated dots by light source LD1 and the density of an area of isolated dots by light source LD2 is smallest is decided as an adjustment ratio, and control is performed such that light sources LD1 and LD2 emit light at the adjusted ratio.

    摘要: A printer detects density of a toner pattern on an intermediate transfer belt, operates a differential value for the detection value, and compares the differential value with a threshold value. If fluctuation of detection values is great and there are detection values of which differential values exceed the threshold value, those detection values are assumed to contain noise due to abnormality of the shape on the belt, and the detection values in such a range are corrected using curve approximation. A tone correction table is updated using the corrected detection values.

    摘要: An image forming device for forming an image on an image carrier using a different grayscale reproduction method for each of two or more different attributes contained in portions of the image. The image forming device forms a different standard pattern in one-to-one correspondence with each different attribute contained in the image portions, using a grayscale reproduction method used for reproducing image portions containing the attribute, detects density of each standard pattern formed by the standard pattern forming unit, sets, for each different attribute, a condition for correcting grayscale of the image portions containing the attribute, in accordance with the detected density, and corrects grayscale of the image portions in accordance with each condition set by the correction condition setting unit.
