    摘要： A color correcting system mountable in an image forming apparatus comprises an imaging unit configured to perform image formation and a control unit configured to acquire a control parameter for use in image formation by the imaging unit and a status parameter indicating a status at the time of image formation. If a value for a color in an image formed by the imaging unit does not exceed a first threshold, and at least one member selected from the group consisting of adhering toner amount, gloss, line width, and line position for the image formed by the imaging unit does not exceed a second threshold, the control unit is configured to determine a control parameter on the basis of the acquired control parameter and the acquired status parameter, such that at least a color difference decreases.

    摘要： In an image forming apparatus, a sensor section which the printed sheets fed from an image forming section pass through or by in a first direction one by one, irradiates each of the passing printed sheets with light elongated in a second direction different, thereby sensing densities of the each of passing printed sheets, on a pixel basis. Further, a control section integrates densities of respectively corresponding line portions in respective non-image areas of sheets of the printed sheets, based on the densities obtained by the sensor section, each of the line portion extending substantially in the first direction and including pixels on substantially a same position in the second direction, thereby obtaining integrated density values, and predicts, based on the obtained integrated density values, that a noise will occur on a printed sheet to be made by the image forming section later on.

    摘要： An image forming apparatus includes: a fixing unit receiving through an inlet a recording medium with a transferred toner image and heat fixing the toner image to the recording medium before discharging the recording medium from an outlet; a suction part for sucking the recording medium through a recording-medium suction opening, the recording medium conveyed on a recording medium conveyance path leading to the inlet; an exhaust passage for discharging to the outside a gas sucked by the suction part; and a filter disposed in the exhaust passage and serving to capture fine particles generated from the fixing unit and sucked in by the suction part.

    摘要： A fixing device is equipped with a lower pressure roller, an upper pressure roller and a fixing belt which fix a toner image onto a sheet, by holding and conveying the sheet by a nip portion, and a control unit which controls rotation of the lower pressure roller. The control unit periodically changes a velocity of rotational drive of the lower pressure roller, at a frequency of which a period is shorter than a time needed for the sheet to pass through the nip portion, when the sheet passes through the nip portion.
