Patent number: 7079806Abstract: An image forming apparatus includes a printer body having a developing portion and a fixing portion therein, a plurality of sheet feeding rollers provided along a sheet discharge path successively and driven to discharge a sheet passing through the fixing portion to an upper portion of the printer body, and a rear cover provided on a side of the printer body to open and close, and having guide ribs to guide the sheet passed through the fixing portion. The image forming apparatus also includes an idle roller provided movably on the rear cover, to contact and rotate with one of the sheet feeding rollers to feed the sheet, and a supplementary guide member provided rotatably on the rear cover and positioned below the idle roller. The supplementary guide member changes a position thereof when the rear cover is open so that the sheet being discharged directly to the guide ribs is prevented from running into the idle roller.Type: GrantFiled: April 30, 2003Date of Patent: July 18, 2006Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-gee Baek, Dong-woo Kim

Patent number: 6892040Abstract: A cooling apparatus of an electrophotographic image forming apparatus includes a cooling fan and a first opening. The cooling fan emits heat in the electrophotographic image forming apparatus to an outside of the electrophotographic image forming apparatus, is installed in any one of two frames that are opposite to each other so as to support a fusing unit, is disposed in a direction where a paper is discharged from the fusing unit, and allows internal air to flow out. The first opening is formed in a first frame that is opposite to a second frame in which the cooling fan is installed, and allows external air to flow into the electrophotographic image forming apparatus. The cooling apparatus is applied to a dry or wet electrophotographic image forming apparatus. The cooling apparatus emits heat generated from a fusing unit to the outside without affecting temperatures of a photosensitive drum and a developer unit so as to prolong a usable period of the photosensitive drum and improve an image quality.Type: GrantFiled: September 27, 2002Date of Patent: May 10, 2005Assignee: Samsung Electronics Co., Ltd.Inventors: Byung-sun Ahn, Dong-woo Kim, Jung-gee Baek
