摘要： An image forming apparatus is provided, including a conveying member configured to convey a long paper along a paper path; an image forming unit which forms an image on the long paper being conveyed by the conveying member along the paper path; an image reading unit which reads a surface of the long paper, the surface having the image formed by the image forming unit; and a color sample member which is arrangeable at a position facing the image reading unit, such that the long paper is conveyed by the conveying member to avoid passing through between the image reading unit and the color sample member. Also included is a switch between a first arrangement in which the image reading unit reads the long paper and a second arrangement in which the image reading unit faces the long paper via the color sample member and reads the color sample member, the switch being made by moving the image reading unit or by moving the color sample member and the conveying member.

摘要： An image forming apparatus forms a color image on a recording medium by superimposing images of colors formed by image forming units. The apparatus includes a processor that: acquires a read image by reading the recording medium on which the color image has been formed; forms a register patch outside a job image forming region of the recording medium; and corrects image forming positions of the image forming units based on the read image that includes the register patch. The register patch includes: a leading end patch and a rear end patch formed with a reference color material; and one or more measurement target color patches formed with measurement target color materials between the leading end patch and the rear end patch. The hardware processor corrects the image forming positions based on relative positions of the leading end patch, the rear end patch, and the measurement target color patches.

摘要： In an image forming apparatus, an image forming unit forms a first image of a first color and a second image of a second color. An obtaining unit obtains information related to relative positions of a first measurement image, which is formed on an image carrier, of the first color and a second measurement image, which is formed on an image carrier, of the second color. A generation unit generates correlation data based on first information corresponding to a first image forming speed and second information corresponding to a second image forming speed. A controller, in a case where the image forming unit forms an image at the second image forming speed, corrects relative positions of the first image and the second image based on the first information in advance and the correlation data.

摘要： An image forming apparatus includes an image carrier, an endless intermediate transfer belt, a primary transfer member, a secondary transfer member, a displacement amount detecting device, and a control unit. The displacement amount detecting device detects displacement amounts of a reference image in a main-scanning direction and a sub-scanning direction. The reference image is formed on the intermediate transfer belt. The displacement amount detecting device includes a density detecting sensor and a surface potential sensor. The density detecting sensor detects a print density of the reference image formed on the intermediate transfer belt. The surface potential sensor detects a surface potential of the reference image. The displacement amount detecting device simultaneously detects the identical reference image using the density detecting sensor and the surface potential sensor to ensure simultaneous detections of displacement amounts in the main-scanning direction and the sub-scanning direction.

摘要： An image forming apparatus includes a sheet feeder, a sheet conveyor, an image former, a fixer, a colorimeter and a processor. The fixer fixes an image formed on a sheet by the image former. The colorimeter is provided on a down-stream side than the fixer in a sheet conveying direction and reads the image. The processor calibrates the colorimeter based on the image read by the colorimeter. When an image for calibration which is formed in advance on a color sample housed in the sheet feeder is made to be read by the colorimeter, the processor controls at least one of the sheet conveyor, the image former and the fixer according to a condition for controlling deterioration of the color sample which is different from a condition of when carrying out an image forming.
