Patent number: 11188017Abstract: An image forming apparatus includes a first unit, a second unit, a first adjusting member, and a second adjusting member. The first unit includes an endless first belt member and a first rotating member that rotates while supporting the first belt member. The second unit includes a rotatable second rotating member that opposes the first rotating member with the first belt member interposed therebetween. The first adjusting member is disposed on either one of the first unit and the second unit to adjust a load between the first rotating member and the second rotating member. The second adjusting member is disposed on the other one of the first unit and the second unit to adjust parallelism between the first rotating member and the second rotating member.Type: GrantFiled: July 16, 2020Date of Patent: November 30, 2021Assignee: FUJIFILM Business Innovation Corp.Inventors: Koichi Sato, Kiyotoshi Kaneyama, Hibiki Sasaki, Kaoru Matsushita, Kentaro Iwamoto, Toshihiko Kamiyama, Takaya Yokoyama
