Sheet conveyance apparatus and image forming system

A sheet conveyance apparatus comprising:

• a conveyance portion configured to convey a sheet;
• a first guide configured to guide the sheet conveyed by the conveyance portion;
• a second guide provided so as to face the first guide and configured to form a sheet conveyance path together with the first guide, the sheet passing through the sheet conveyance path, the second guide being pivotable between a first position in which the sheet conveyance path is formed and a second position in which the sheet conveyance path is opened;
• a holding portion configured to hold the second guide at the second position;
• a cover configured to be movable between a closed position in which the cover covers the second guide and an open position in which the second guide is exposed to outside of the sheet conveyance apparatus;
• a first abutting portion provided on the cover and configured to abut the second guide;
• and
• a second abutting portion provided on the cover and configured to abut the second guide at a position different from that of the first abutting portion,
• wherein the first abutting portion is disposed such that in a state where the second guide is held at the second position by the holding portion, when the cover is moved to the closed position from the open position, the first abutting portion abuts the second guide to release the second guide held by the holding portion, and
• wherein the second abutting portion is disposed such that in a state where the cover is positioned at the closed position, the second abutting portion abuts the second guide to position the second guide at the first position.
