Sheet conveyance apparatus and image forming apparatus

A sheet conveyance apparatus comprising:

• a sheet conveyance roller pair configured to convey a sheet;
• a first opening and closing guide provided pivotably about a first shaft and configured to open to a first opened position in which a first conveyance path through which a sheet is conveyed by the sheet conveyance roller pair is opened and configured to close to a first closed position in which a sheet is conveyed in the first conveyance path;
• a second opening and closing guide provided pivotably about a second shaft that differs from the first shaft and configured to open to a second opened position in which a second conveyance path is opened and configured to close to a second closed position in which a sheet is conveyed in the second conveyance path;
• a first member provided on the first opening and closing guide;
• and
• a second member provided on the second opening and closing guide and configured to pivot between a first position and a second position with respect to the second opening and closing guide, wherein the first position is a position interfering with a movement locus of the first member and the second position is a position not interfering with the movement locus of the first member in a state where the first opening and closing guide is pivoted when the second opening and closing guide is in the second closed position,
• wherein while the first opening and closing guide is pivoted from the first closed position to the first opened position in a state where the second opening and closing guide is at the second closed position, the second opening and closing guide pivots from the second closed position toward the second opened position by a force transmitted to the second opening closing guide by the first member interfering with the second member, and
• wherein while the first opening and closing guide is pivoted from the first opened position to the first closed position in a state where the second opening and closing guide is at the second closed position, the second member is pivoted from the first position to the second position by interference of the first member with the second member, and the first opening and closing guide is configured to pivot to the first closed position, wherein in a state where the first opening and closing guide is at the first closed position, the second member is positioned at the first position.
