  • Patent number: 9158262
    Abstract: An image forming apparatus contains a registration correction portion correcting an inclination of the sheet of paper by hitting a forward end of the sheet of paper against a pair of registration rollers, a detection portion that detects an amount of deviation in the sheet of paper, a control portion that calculates a command value of movement for correcting the amount of deviation and a moving portion that moves the registration rollers toward a direction which is perpendicular to a sheet-conveying direction based on the command value of movement with the sheet of paper being nipped with the registration rollers. The control portion controls the moving portion so that the movement of the registration rollers finishes before a limited time of movement or below an upper limit of movement set in relation to the command value of movement.

  • Patent number: 8892023
    Abstract: 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.

  • Publication number: 20130142525
    Abstract: 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.
