IMAGE-FORMING APPARATUS

摘要

An image-forming apparatus contains an image-forming portion, a first conveying portion that is arranged at an upstream side of the image-forming portion along a sheet conveying direction, a second conveying portion that is arranged at an upstream side of the first conveying portion along the sheet conveying direction and a control portion. The control portion controls the first conveying portion to move a pair of registration rollers along a direction that is orthogonal to the sheet conveying direction while the pair of registration rollers nips the sheet when conveying the sheet to the image-forming portion. The control portion controls the second conveying portion to move one of the pair of conveying rollers along the direction that is orthogonal to the sheet conveying direction while the pair of conveying rollers does not nip the sheet.

主权项

1. An image-forming apparatus comprising:
an image-forming portion that forms an image on a sheet; a first conveying portion that is arranged at an upstream side of the image-forming portion along a sheet conveying direction and includes a pair of conveying members; a second conveying portion that is arranged at an upstream side of the first conveying portion along the sheet conveying direction and includes a pair of conveying members; and a control portion that controls the first conveying portion to move the pair of conveying members of the first conveying portion along a direction that is orthogonal to the sheet conveying direction while the pair of conveying members of the first conveying portion nips the sheet, when conveying the sheet to the image-forming portion, and controls the second conveying portion to move at least one of the pair of conveying members of the second conveying portion along the direction that is orthogonal to the sheet conveying direction while the pair of conveying members of the second conveying portion inhibits the sheet from being nipped.
