Patent number: 11650524Abstract: A fixing device includes a fixing rotating member, a heater, a fixing pad, a pressurizing member, a lubricant, and a surface layer. The fixing rotating member is configured to fix a toner image on a recording medium and is heated by the heater. The fixing pad is positioned on an inner circumferential side of the fixing rotating member, and presses the fixing rotating member from the inner circumferential side. The pressurizing member faces an outer circumferential surface of the fixing rotating member, and forms a nip for fixing between the pressurizing member and the fixing rotating member. The lubricant is applied to the fixing rotating member. The surface layer is disposed in a vicinity of an end portion of a pressurizing surface of the fixing pad and returns the lubricant to a longitudinal central side of the pressurizing surface.Type: GrantFiled: June 8, 2021Date of Patent: May 16, 2023Assignee: TOSHIBA TEC KABUSHIKI KAISHAInventor: Atsushi Yamazoe
