Publication number: 20190079433Abstract: An image forming device includes an image carrier carrying an image, a transfer device including paired transfer members that transport the image carrier and a recording medium, a grounded guide member that guides the recording medium to a transfer region, and a transfer power source that produces an electric field in the transfer region causing the image to be transferred onto the recording medium. The transfer power source includes a first transfer power source that imparts a first transfer voltage to one of the paired transfer members, and a second transfer power source that, when the recording medium has a predetermined resistance value or less, or is of low resistance having a conductive layer along a medium substrate face, imparts a second transfer voltage of opposite polarity and having an absolute value less than or equal to the first transfer voltage to the other of the paired transfer members.Type: ApplicationFiled: March 9, 2018Publication date: March 14, 2019Applicant: FUJI XEROX CO., LTD.Inventors: Kanji WATANABE, Daisuke TANAKA

Patent number: 10175613Abstract: An image forming apparatus includes a transport member that transports a continuous medium as a result of a transport surface of the transport member making contact with the continuous medium and a transfer device that is disposed on a downstream side in a direction in which the transport member transports the medium and that transfers an image onto the medium, which extends to the transport member, as a result of a transfer surface of the transfer device making contact with the medium. A moving speed of the transfer surface is lower than a moving speed of the transport surface when the medium is transported.Type: GrantFiled: May 1, 2017Date of Patent: January 8, 2019Assignee: FUJI XEROX CO., LTD.Inventor: Kanji Watanabe

Patent number: 10168646Abstract: An image forming apparatus includes an image holding body, a transfer member, and a controller. The image holding body holds an image formed of toner. The transfer member is brought into contact with a continuous medium so as to transfer the image held by the image holding body to the continuous medium, and the transfer member is able to be brought into contact with and separated from the image holding body. The controller causes the transfer member to be separated from the image holding body, and after that, causes the image holding body to move so as to detect an inspection image formed on the image holding body, thereby adjusting, as image quality adjustment, a deviation of a position of the image or a deviation of density of the image to be formed.Type: GrantFiled: May 11, 2017Date of Patent: January 1, 2019Assignee: FUJI XEROX CO., LTD.Inventors: Masafumi Okabe, Kanji Watanabe
