Patent number: 8226076Abstract: When a sheet is loaded to the sheet tray, the position of a trailing edge regulating section is set in response to the size of an insert sheet. Owing to this, the print sheet ejected from the ejection rollers onto the sheet tray falls onto the surface of the insert sheet. Further, when a booklet with an insert sheet placed therein is produced, an insert sheet is supplied to the sheet tray along the second conveying path. The shift amount of the execution position of center folding or the execution position of center stitching with respect to the sheet bundle is calculated in conformity to the finishing form of the booklet containing the insert sheet.Type: GrantFiled: October 5, 2010Date of Patent: July 24, 2012Assignee: Konica Minolta Business Technologies, Inc.Inventors: Takumi Shirakuma, Takeshi Tamada, Eiji Sugimoto, Teruhiko Toyoizumi, Hideo Yamane

Patent number: 7313355Abstract: There is described an image forming apparatus, which forms high quality images free from a phenomenon of inter-sheet adhesion. The image forming apparatus includes a conveyance section to convey the transfer material along a conveying path; a cooling device disposed along the conveying path to cool the transfer material just after the toner image is fixed with heat; a controller-to control the conveyance section and the cooling device; and a first transfer-material detecting device disposed at a position adjacent to and upstream from the cooling device, in order to detect the transfer material coming into the conveying path. When the first transfer-material detecting device detects the transfer material coming, the controller controls the conveyance section to decelerate a conveyance velocity of the transfer material to a decelerated velocity lower than a normal conveyance velocity, so that the transfer material passes through the conveying path at the decelerated velocity.Type: GrantFiled: December 13, 2005Date of Patent: December 25, 2007Assignee: Konica Minolta Business Technologies, Inc.Inventors: Akifumi Isobe, Satoshi Sakata, Hiroyuki Watanabe, Hideo Yamane
