12. An image forming apparatus comprising:
an image forming unit; and
a sheet conveying apparatus that includes:
a conveying unit configured to convey a sheet,
a casing including a conveying path through which the sheet passes,
a cover configured to move between a closed position at which the conveying path is covered and an open position at which the conveying path is exposed,
a drive source configured to drive the conveying unit,
a drive transmission unit including a drive transmission belt and a rotatable member configured to engage with the drive transmission belt, wherein the drive transmission unit is configured to transmit a driving force of the drive source to the conveying unit via the drive transmission belt and the rotatable member,
a tensioner configured to move between a pressing position at which the drive transmission belt is pressed and a retracted position retracted from the pressing position, and
a moving member configured to move the tensioner from the pressing position toward the retracted position,
wherein a magnitude of tension exerted on the drive transmission belt is lower when the tensioner is at the retracted position than when the tensioner is at the pressing position, and
wherein the moving member moves the tensioner from the pressing position toward the retracted position in conjunction with movement of the cover from the closed position to the open position.
