摘要： An image forming apparatus includes a first main body side plate, a second main body side plate, a drive side plate, a drive gear train disposed between the drive side plate and the first main body side plate, and a cable guide disposed between the first main body side plate and the drive side plate. The drive gear train includes a rotary gear, and the cable guide overlaps with a part of the rotary gear when viewed in a rotational axis direction of the rotary gear.

摘要： A sheet conveying apparatus includes a conveying unit, a drive source, a drive transmission unit, a tensioner, and a moving member. The drive source drives the conveying unit to convey a sheet. The drive transmission unit includes a drive transmission belt and a rotatable member to engage with the drive transmission belt. The drive transmission unit transmits a driving force of the drive source to the conveying unit via the drive transmission belt and the rotatable member. The tensioner moves between a pressing position at which the drive transmission belt is pressed and a retracted position retracted from the pressing position. The moving member moves the tensioner from the pressing position toward the retracted position. The 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.
