摘要： An image forming apparatus includes a rotatable image bearer, a transfer rotator, a detector, and circuitry. The image bearer bears an image. The transfer rotator transfers the image from the image bearer onto a recording medium sandwiched and conveyed between the image bearer and the transfer rotator. The detector detects length information indicating a length, in a direction of conveyance of the recording medium, of the image on the recording medium. The circuitry corrects a correction value, based on the length information detected by the detector and a target value of the length information, to correct an image magnification, in the direction of conveyance of the recording medium, of the image to be formed on the recording medium. The circuitry controls an image forming operation of forming the image on the recording medium with the correction value.

摘要： An image forming apparatus includes an intermediate transfer body, a plurality of image bearers, a plurality of developing devices, a plurality of primary transfer devices, a secondary transfer device, and a cleaner. The plurality of image bearers are disposed side by side along the intermediate transfer body. In a refreshing mode, the plurality of developing devices form toner images on the plurality of image bearers during a non-image-formation period and the cleaner cleans a surface of the intermediate transfer body. In the refreshing mode, a toner image formed on one image bearer of the plurality of image bearers, which differs from a most downstream image bearer of the plurality of image bearers in a direction of conveyance of the intermediate transfer body, reaches the cleaner first of the toner images formed on the plurality of image bearers.

摘要： An image forming apparatus includes a plurality of image bearers, a plurality of developing devices, a plurality of first transfer devices disposed opposite the plurality of image bearers, a second transfer device, a cleaning device to remove toner remaining on the intermediate transferor after a secondary transfer process, and a processor to control the plurality of developing devices to perform a refresh process to discharge toner from the plurality of developing devices to the plurality of image bearers. Among toner of the colors, toner having a first circularity first reaches the cleaning device and toner having a second circularity higher than the first circularity subsequently reaches the cleaning device in the refresh process.
