    摘要: An image forming apparatus includes a duplex conveyance path where a recording medium can be reversed and re-fed; and an output image detector to detect an image or a test pattern formed on a surface of the recording medium. The image forming apparatus is configured to: detect the test pattern formed on the first side of the recording medium by the output image detector; adjust and correct image forming conditions based on the detection result of the detector; convey the recording medium the first side of which the test pattern is formed on, to a duplex conveyance path; re-feed the recording medium and form a test pattern for verifying correction effect on a backside of the recording medium after correcting and updating the image forming conditions; and detect the test pattern formed on the backside of the recording medium again by the output image detector, thereby verifying the correction effect.

    摘要: An image forming apparatus includes an image carrier; a developing device; a transfer device; and a fixing device. An electrostatic latent image formed on the image carrier is rendered visible as a toner image by depositing the toner by the developing device, and the toner image is transferred by the transfer device and fixed onto a recording medium by the fixing device and output. The apparatus further includes a density fluctuation meter including a rotary position detector, a density fluctuation detector, and a density fluctuation storage; a density fluctuation extractor unit including a first extractor, a second extractor, and a density fluctuation storage; and a control table generator unit including a control table generator and a control table storage, so that based on the control table stored in the control table storage, the voltage to be applied to the developing device is controlled and the toner image is output.

    摘要: In an image forming apparatus, a first controller forms a first image pattern on an image bearer and determines a first image formation condition based on a detection result of density of a toner image. The first controller then controls a toner image forming device based on the first image formation condition. A second controller forms a second image pattern different from the first image pattern on an image bearer and determines a second image formation condition based on a detection result of density of a toner image. The second controller then controls a toner image forming device based on the second image formation condition.

    摘要: In a reuse method for reusing a reusable device and a sensor of a first image forming apparatus having a first process linear velocity in a second image forming apparatus having at least one second process linear velocity different from the first process linear velocity, the reusable device and the sensor are installed in the first image forming apparatus, and when the first image forming apparatus switches from the first process linear velocity to the second process linear velocity at an initial state before the reusable device is used, output of the sensor at the second process linear velocity is measured. When information on the output of the sensor at the second process linear velocity is stored, the reusable device and the sensor are removed from the first image forming apparatus and installed in the second image forming apparatus.
