A medium transporting apparatus including a paddle that comes in contact with a medium discharged on a first tray including an upstream end matching member and that rotates to move the medium towards the upstream end matching member, and a low frictional resistance member configured to switch between an advanced state advanced from outside a medium mount region of the first tray to a first region, and a retracted state retracting from the first region to an outside of the medium mount region. The low frictional resistance member is, after a first medium is mounted on the first tray, switched from the retracted state to the advanced state, and is interposed between the first medium and a second medium when, after discharging the first medium, moving the second medium discharged from a pair of discharge rollers towards the upstream end matching member with the paddle.

A sheet stacking apparatus includes a frame, a round member directly or indirectly connected to the frame, and an arm directly or indirectly connected to the frame. The arm is rotatable to rotate between a first position and a second position. The arm is positioned to bias sheets toward the round member when in the first position, and the arm is positioned to bias the sheets away from the round member when in the second position.

A sheet conveying device includes a sheet-discharging roller, a sheet-discharge tray, a sheet-discharge stopper, and a stopper urging portion including a contact member and an urging member. The sheet-discharge stopper has a first surface and a second surface located on a back side of the first surface and is pivotable between a non-use state in which the second surface faces upward and a use state in which the first surface faces upward. The sheet-discharge stopper is pivotable, in the use state, between a first use position and a second use position at which a distal end is lowered from the first use position. The sheet-discharge stopper is in contact with the contact member in the use state, and an area, of the sheet-discharge stopper is located below the second surface in the non-use state.

A sheet feeding apparatus includes a sheet accommodating unit, a sheet feeding unit, a first lifting portion, a second lifting portion, and a linear member configured to liftably support the first lifting portion and the second lifting portion, and stretched between the first lifting portion and the second lifting portion on a lower side of the stacking surface. In addition, a first winding unit, a second winding unit, and an adjustment member adjust both a first distance of the linear member between the first winding unit and the first lifting portion and a second distance of the linear member between the second winding unit and the second lifting portion.

An image forming apparatus includes a drawer unit, a sheet inverting unit, a sheet guide plate, and a projection. The drawer unit is drawable from an apparatus body. The sheet inverting unit is disposed in the apparatus body, and pulls a sheet into a lower portion of the drawer unit to invert the sheet. The sheet guide plate is disposed on the sheet inverting unit to face the drawer unit, and includes a recess extending in a pull-out direction of the drawer unit that crosses a direction in which the sheet is transported. The projection protrudes toward the recess from a portion of a lower surface of the drawer unit facing the sheet guide plate near a pull-out start point in the pull-out direction and on a rear of a transport area of the sheet.
