Sheet conveyance apparatus

A sheet conveyance apparatus comprising:

• a conveyance roller configured to convey a sheet;
• an abutment member disposed downstream of the conveyance roller and extending along a sheet conveyance direction, the abutment member comprising an abutment surface against which a side edge, in a width direction orthogonal to the sheet conveyance direction, of the sheet abuts, and configured to correct a skew of the sheet;
• an obliquely conveying roller disposed downstream of the conveyance roller in the sheet conveyance direction, and configured to convey the sheet such as the side edge of the sheet is conveyed toward the abutment surface;
• a sheet side edge detection portion configured to detect a position of the side edge of the sheet in the width direction and change an output value in response to the position of the side edge of the sheet conveyed by the obliquely conveying roller;
• and
• a control unit configured to control that a conveyance force, in the width direction, by the obliquely conveying roller in response to a detection result of the sheet side edge detection portion becomes smaller than that in an abutment movement, the abutment movement being a movement in which the side edge of the sheet is brought to abut against the abutment surface by the obliquely conveying roller conveying the sheet.
