Publication number: 20160259282Abstract: A fixing device includes a pressure applying unit that is provided facing a heating unit. The pressure applying unit includes an endless belt-shaped member that rotates by being driven by rotation of the heating unit, and a retainer that retains the endless belt-shaped member in a movable manner. The retainer has an upstream adjuster that is located at an upstream side of the endless belt-shaped member in a rotational direction thereof and that has a curved shape with a center, in a longitudinal direction of the retainer, which is a most bulging area from which the upstream adjuster decreases in height toward opposite ends of the upstream adjuster.Type: ApplicationFiled: September 2, 2015Publication date: September 8, 2016Applicant: FUJI XEROX CO., LTD.Inventors: Nobuyoshi KOMATSU, Masaki NAGATA, Motoi NOYA, Yusuke KANAI

Publication number: 20160246231Abstract: A fixing device includes a fixing roller, a rotatable endless belt forming a nip between the fixing roller and the belt, a heating member whose heat source heats the nip, a support member disposed in the belt to face the fixing roller and having a surface having a substantially non-arc shape in a rotation direction of the belt and being in contact with an inner surface of the belt to sandwich the belt between the support member and the fixing roller, and a pressing member including guiding members that support and guide end edges of the belt. The guiding members each have a groove having inner and outer walls that guide an edge of the belt in a direction in which a rotation axis of the belt extends and a substantially arc-shaped bottom surface that extends around the axis and along which an end surface of the belt slides.Type: ApplicationFiled: August 31, 2015Publication date: August 25, 2016Applicant: FUJI XEROX CO., LTD.Inventors: Motoi NOYA, Masaki NAGATA, Nobuyoshi KOMATSU, Yusuke KANAI

Patent number: 6853832Abstract: The present invention provides an image forming apparatus having dimensions comparable to or smaller than those of conventional color image forming apparatus and adapted to produce a hard copy of photographic image quality. The image forming apparatus of the present invention has a first fixing device that fixes a toner image transferred to a recording medium, a second fixing device that re-fixes the toner image fixed on the recording medium by the first fixing device, and a switch section that selects the first route or the second route for the recording medium to be discharged. The first route passes through the first fixing device and allows the recording medium to be discharged immediately thereafter without passing through the second fixing device. The second route passes through the first fixing device and subsequently the second fixing device, and then allows the recording medium to be discharged.Type: GrantFiled: March 7, 2003Date of Patent: February 8, 2005Assignee: Fuji Xerox Co., Ltd.Inventors: Motoi Noya, Yutaka Nogami, Yoshio Kanesawa

Patent number: 6850727Abstract: An image-forming apparatus is provided which includes: an image forming part that forms an unfixed toner image on a recording sheet; a first fixing part that performs primary fixation to the recording sheet that bears the unfixed toner image; and a second fixing part that performs secondary fixation to the recording sheet fixed by the first fixing part. In the image-forming apparatus, the second fixing part exists above the image forming part.Type: GrantFiled: February 5, 2003Date of Patent: February 1, 2005Assignee: Fuji Xerox Co., Ltd.Inventors: Motoi Noya, Yutaka Nogami, Yoshio Kanesawa
