Patent number: 11494602Abstract: 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.Type: GrantFiled: August 11, 2021Date of Patent: November 8, 2022Assignee: RICOH COMPANY, LTD.Inventors: Takuya Akiyama, Seiichi Kogure, Atsushi Nakamoto, Daisuke Hamada, Yuuki Aoki, Yutaka Goto

Patent number: 11366404Abstract: An image forming apparatus includes an image bearer, a transfer rotator, an adjuster, and circuitry. The image bearer bears a toner image. The transfer rotator contacts the image bearer to form a transfer nip between the transfer rotator and the image bearer. The transfer rotator transfers the toner image from the image bearer onto a sheet conveyed to the transfer nip. The adjuster adjusts at least one of a relative difference in linear velocity of the transfer rotator to the image bearer at the transfer nip and a relative contact pressure of the transfer rotator to the image bearer at the transfer nip. Based on a difference in image magnification, in a direction of conveyance of the sheet, of toner images transferred onto surfaces of one or more sheets conveyed to the transfer nip, the circuitry causes the adjuster to reduce the difference in image magnification.Type: GrantFiled: April 9, 2021Date of Patent: June 21, 2022Assignee: RICOH COMPANY, LTD.Inventors: Atsushi Nakamoto, Seiichi Kogure, Daisuke Hamada, Takuya Akiyama, Yuuki Aoki, Yutaka Goto
