Sheet conveyance apparatus and image forming apparatus having multiple driven rollers supported by guides in a curved conveyance path

A sheet conveyance apparatus comprising:

• a first conveyance unit configured to form a first nip portion, the first conveyance unit being configured to convey a sheet in a sheet conveyance direction by the first nip portion;
• a second conveyance unit arranged downstream of the first conveyance unit in the sheet conveyance direction and configured to form a second nip portion, the second conveyance unit being configured to convey the sheet by the second nip portion;
• and
• a guide unit configured to form a curved conveyance path that curves with respect to the sheet conveyance direction, the guide unit being configured to guide the sheet conveyed by the first conveyance unit to the second conveyance unit,
• wherein the guide unit includes:
• a first guide;
• a second guide configured to form at least a part of the curved conveyance path with the first guide, the first guide forming an outer side of the curved conveyance path, the second guide forming an inner side of the curved conveyance path;
• a first driven roller rotatably supported by the first guide, and rotatably driven with respect to the sheet by coming into contact with the sheet, at a first contact point, conveyed through the curved conveyance path by the second conveyance unit;
• and
• a second driven roller rotatably supported by the second guide and arranged downstream of the first driven roller in the sheet conveyance direction, the second driven roller being rotatably driven with respect to the sheet by coming into contact with the sheet, at a second contact point, conveyed through the curved conveyance path by the second conveyance unit,
• wherein, when viewed in a width direction orthogonal to the sheet conveyance direction, a part of the first guide is formed so as not to intersect with a straight line passing through the first contact point and the second contact point, and is positioned upstream of the first contact point in the sheet conveyance direction, and
• wherein a horizontal component of the sheet conveyance direction in which the first nip portion of the first conveyance unit conveys the sheet is opposite to a horizontal component of a direction in which the second nip portion of the second conveyance unit conveys the sheet.
