Patent number: 8346150Abstract: In a fixing device, an opposing member contacts a heating member to form a fixing nip between the heating member and the opposing member. A driver rotatively drives at least one of the heating member and the opposing member. A sheet supplier supplies and conveys a sheet to the fixing nip. A recording medium bearing an unfixed toner image is conveyed through a gap between the sheet and the opposing member at the fixing nip with a side of the recording medium bearing the unfixed toner image facing the sheet. At least one of the rotating heating member and the rotating opposing member applies a driving force to the sheet supplied to the fixing nip while the sheet contacts the sheet supplier to apply tension to the sheet at a position upstream from the fixing nip in a sheet conveyance direction.Type: GrantFiled: March 31, 2010Date of Patent: January 1, 2013Assignee: Ricoh Company, Ltd.Inventors: Tomofumi Inoue, Shuuichi Nakagawa, Hidekazu Shono
