Patent number: 8892023Abstract: An image forming apparatus acquires an amount of deflection of the transporting sheet from a reference position thereof and calculates a required shift amount of the sheet. It determines whether or not the sheet is shifted frontward. If so, the image forming apparatus acquires a second specified shift value which is determined based on an urging force and the required shift amount using a second correction equation. Alternatively, if the sheet is shifted backward, the image forming apparatus acquires a first specified shift value which is determined based on the urging force and the required shift amount using a first correction equation. The image forming apparatus performs a registration roller shift correction based on the acquired first or second specified shift value.Type: GrantFiled: October 24, 2012Date of Patent: November 18, 2014Assignee: Konica Minolta Business Technologies, Inc.Inventors: Yusuke Kawanago, Takahiro Okubo, Masahiro Matsuo, Yoshiteru Kawakami, Haruki Motegi, Osamu Yoshimura, Kunihiro Kawachi, Ken Nonaka

Publication number: 20130142525Abstract: An image forming apparatus includes a fixing section, a de-curling section, and a control section. The de-curling section has a de-curling nip portion that presses a sheet to correct a curl caused in the sheet, and a corrective force thereof to press the sheet changes at least in two steps. The control section increases the conveyance speed of the sheet after a rear end of the sheet has passed the fixing nip portion when the de-curling section supports by sandwiching the sheet with a weakly-pressing force. When the de-curling section supports by sandwiching the sheet with a strongly-pressing force, the controller increases the conveyance speed of the sheet after the rear end of the sheet has passed the fixing nip portion and the de-curling nip portion.Type: ApplicationFiled: November 29, 2012Publication date: June 6, 2013Inventors: Ken NONAKA, Yoshiteru KAWAKAMI, Takahiro OKUBO, Haruki MOTEGI, Masahiro MATSUO, Yusuke KAWANAGO, Osamu YOSHIMURA
