  • Publication number: 20180150014
    Abstract: An image forming apparatus includes the following. An upstream second conveying roller and a downstream second conveying roller form a loop on the long sheet. A deviation amount detector detects a deviation amount of the long sheet. A loop amount detector detects a loop amount in two positions in a width direction. A speed controller controls a rotating speed of the upstream second conveying roller and the downstream second conveying roller based on a deviation amount and a difference of loop amounts in two positions. Each of the upstream second conveying roller and the downstream second conveying roller includes a near roller and a far roller. The speed controller controls the rotating speed of the near roller and the far roller based on the deviation amount and the difference of the loop amounts in the two positions.

  • Patent number: 8783683
    Abstract: An image forming apparatus acquires sheet information indicating paper weight or the like of a transported sheet of paper. The apparatus also has a control portion and shifts a reference position which has been previously set to a direction orthogonal to a transporting direction of the sheet of paper based on the paper weight or the like of the transported sheet of paper. A deviation sensor detects a deviation of the sheet of paper with regard to the shifted reference position along the direction orthogonal to the transporting direction of the sheet of paper. A sheet shift portion shifts the sheet of paper to the shifted reference position based on the deviation detected by the deviation sensor.

  • Patent number: 8764003
    Abstract: When conveying an envelope, a posture of the envelope is corrected by hitting a closed portion of the envelope, which is opposite side of an opened portion of the envelope, against a nip portion between upper and lower rollers of the pre-registration rollers and the envelope is then conveyed with the envelope being nipped by the upper and lower rollers of the pre-registration rollers. The upper and lower rollers of the pre-registration rollers nip the envelope to remove air from the envelope. When setting an envelope mode to control a conveying speed of the envelope based on a coverage rate of an image to be formed on the envelope, the conveying speed of the envelope is controlled by adjusting a rotation speed of the registration rollers based on the coverage rate of the set envelope mode.
