Sheet conveyance apparatus, image forming apparatus, and image forming system

A sheet conveyance apparatus comprising:

• a conveyance unit configured to convey a sheet;
• and
• a skew correction unit configured to correct skew of the sheet conveyed by the conveyance unit,
• wherein the skew correction unit includes a first skew correction roller pair, a second skew correction roller pair, a first motor, and a separate mechanism,
• wherein the first skew correction roller pair includes a first drive roller and a first driven roller arranged to face the first drive roller and configured to be rotatably driven by the first drive roller,
• wherein the second skew correction roller pair includes a second drive roller and a second driven roller arranged to face the second drive roller and configured to be rotatably driven by the second drive roller, the second skew correction roller pair being provided in alignment with the first skew correction roller pair in a width direction perpendicular to a sheet conveyance direction,
• wherein the separate mechanism includes an interlocking member configured to interlock the first driven roller and the second driven roller, and
• wherein the separate mechanism is configured to move the first driven roller and the second driven roller to contact positions and separated positions by driving the first motor to move the interlocking member, the contact positions being positions where the first driven roller and the second driven roller respectively come into contact with the first drive roller and the second drive roller, the separated positions being positions where the first driven roller and the second driven roller are respectively separated from the first drive roller and the second drive roller.
