Sheet conveyance apparatus, image forming apparatus and image forming system

A sheet conveyance apparatus comprising:

• an apparatus body comprising a conveyance portion configured to convey a sheet;
• a door supported in an openable/closable manner with respect to the apparatus body around a pivot shaft, and configured to pivot to a first position that is opened with respect to the apparatus body and to a second position that is opened further with respect to the apparatus body than the first position, the door being configured to expose the conveyance portion at both the first and second positions;
• a pivot member pivotably supported with respect to the apparatus body around the pivot shaft;
• an urging portion provided between the door and the pivot member, and configured to urge the door and the pivot member to approach each other so that the door and the pivot member are pivoted integrally with respect to the apparatus body;
• and
• a regulating portion configured to regulate pivoting of the pivot member at a predetermined pivot angle with respect to the apparatus body in a case where the door is positioned at the first position,
• wherein the door is configured to be retained at the first position in a state where no external force is applied to the door, is pivoted relatively with respect to the pivot member against urging force of the urging portion while the door moves from the first position to the second position, and is urged toward the first position by the urging portion in a case where the door is positioned at the second position.
