Patent number: 9126778Abstract: An image forming system includes a feed section, a transport section, a transport position adjuster, and a load-position moving unit. The feed section feeds a sheet. The transport section transports the sheet fed from the feed section. The transport position adjuster adjusts a position of the sheet in an intersecting direction that intersects with a transport direction of the sheet transported by the transport section. The load-position moving unit moves the position, in the intersecting direction, of the sheet loaded in the feed section so as to reduce an adjustment amount by which the position is adjusted in the intersecting direction by the transport position adjuster if the adjustment amount is larger than a predetermined amount.Type: GrantFiled: May 14, 2014Date of Patent: September 8, 2015Assignee: FUJI XEROX CO., LTD.Inventors: Takuyoshi Kimura, Yoshinori Koike, Takehiko Koizumi

Patent number: 8752834Abstract: An image forming apparatus includes a fixing device including a pair of first rotating members; a first transport path having a curved portion where a recording medium is curved, the first transport path being for transporting the recording medium to which the image is fixed by the pair of first rotating members; a first transporting section including a pair of second rotating members provided downstream from the curved portion of the first transport path; and a controller that controls so that, while the recording medium is interposed between the pair of first rotating members and the pair of second rotating members, a peripheral velocity of the second rotating members and a peripheral velocity of the first rotating members are reduced at the same time, or the peripheral velocity of the second rotating members is reduced before reducing the peripheral velocity of the first rotating members.Type: GrantFiled: June 3, 2011Date of Patent: June 17, 2014Assignee: Fuji Xerox Co., Ltd.Inventors: Naohito Otsuki, Yoshinori Koike, Shouichi Maeda, Junichi Asaoka
