Claim 4:
5. The sheet conveying apparatus according to claim 1, wherein
the first conveying member is constituted by a pair of conveying rollers that nips and conveys a sheet,
the sheet conveying apparatus further includes:
a roller moving unit capable of moving at least one of the pair of conveying rollers as the first conveying member to a nip position bringing the pair of conveying rollers into a nip state for sheet conveyance and a nip release position where the pair of conveying rollers are separated from the nip position; and
a fourth conveying member provided upstream relative to the first conveying member in the conveying direction and configured to convey the sheet toward the first conveying member,
when a sum of lengths in the conveying direction of a plurality of sheets stopped on the conveying belt is larger than a distance between the first and second conveying members and smaller than a distance between the second and fourth conveying members, the roller moving unit sets the first conveying member at the nip release position in a state where a front end of a most downstream sheet in the conveying direction among the plurality of sheets is located upstream relative to the second conveying member in the conveying direction and where a rear end of the most upstream sheet in the conveying direction among the plurality of sheets is located downstream relative to the fourth conveying member in the conveying direction.
