    摘要: There is provided an image forming apparatus in which an image forming speed is changed in a state where toner is provided between a photosensitive drum and an intermediate transfer member. Therefore, even if a speed difference between the photosensitive drum and the intermediate transfer member is generated, a drive torque can be suppressed, and deterioration caused by abrasion of the photosensitive drum and the intermediate transfer member can be reduced.

    摘要: There is provided an image forming apparatus including a rotation member used for image forming and a detector for detecting light from the rotation member. First waveform data of an image-formed surface used to form an image on the rotation member is acquired by the detector. Second waveform data of the image-formed surface used to form an image on the rotation member is acquired. The second waveform data includes at least part of a detected section of the first waveform data. Information on the actual circumference of the rotation member is calculated based on matching between the acquired first and second waveform data. The acquired first waveform data and second waveform data are compared to determine whether or not to use the calculated information on the circumference. When it is determined not to use the calculated information on the circumference, information on the circumference of the rotation member is recalculated.

    摘要: There is provided an image forming apparatus that can suppress the formation of creases when forming images on both surfaces of a sheet and can greatly reduce the incidence of unprinted areas. The image forming apparatus has a sheet stacking section in which sheets are stacked, a sheet conveying section that conveys a sheet, an image forming section that forms an image on the sheet while the sheet is conveyed, a re-conveying section that again conveys the sheet with the image formed on a first surface thereof to the image forming section, and a sheet feeding section that feeds a sheet from the sheet stacking section or the re-conveying section to the image forming section. When a sheet is fed from the sheet stacking section for image formation on the first surface of the sheet by the image forming section, the sheet is fed at a first speed, and when a sheet is fed from the re-conveying section for image formation on a second surface of the sheet by the image forming section, the sheet is fed at a second speed that is slower than the first speed and is slower than the speed at which the sheet is conveyed by the sheet conveying section.

    摘要: An image forming apparatus includes a transfer roller that can be separated from an intermediate transfer belt. When an operational mode is switched from a multicolor mode to a mono-color mode, the image forming apparatus changes a rotational speed of the intermediate transfer belt to a level slower than a rotational speed of the intermediate transfer belt to be set in the multicolor mode to transfer a toner image to the intermediate transfer belt, then separates a first transfer member from the intermediate transfer belt, and after the first transfer member is separated from the intermediate transfer belt, the image forming apparatus increases the rotational speed of the intermediate transfer belt to a rotational speed to be set in the mono-color mode to transfer the toner image to the intermediate transfer belt.

    摘要: There is provided an image forming apparatus that accurately obtains the dynamic characteristic of the apparatus when a foreign substance is adhered to a driving roller for driving an endless belt, such as a facing roller. To accomplish this, the image forming apparatus uses an optical sensor to detect information of a foreign substance on the facing roller. When it is determined that there is no foreign substance information, the image forming apparatus executes profile detection of an intermediate transfer belt using the nominal circumference of the facing roller. When the optical sensor detects foreign substance information, the image forming apparatus measures the circumference of the facing roller, and performs profile detection of the intermediate transfer belt using the measured circumference of the facing roller.
