    摘要: 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.

    摘要: 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.
