1. An image forming apparatus comprising:
a casing having an opening between an upper face and a lateral face;
an upper cover covering an upper side of the opening of the casing; and
a lateral cover covering a lateral side of the opening, wherein
the lateral cover is provided with a manual sheet feeding tray,
the manual sheet feeding tray is switchable between a storage state where the manual sheet feeding tray forms a part of an external wall of the casing in a posture along the lateral cover and a usage state where a sheet is placed on the manual sheet feeding tray in a posture inclined upward toward the outside on the lateral side of the casing,
the lateral cover is supported in a turnable manner around a first turning axis extending in a horizontal direction at a lower end edge portion of the lateral cover, and displaceable between a closing position where the lateral cover covers the lateral side of the opening and an opening position where the lateral cover turns outward on a lateral side of the casing and opens the lateral side of the opening,
the upper cover is supported in a turnable manner around a second turning axis extending in a horizontal direction in parallel with the first turning axis at an end edge portion on opposite side to the lateral face of the casing in the opening, and displaceable between a closing position where the upper cover covers the upper side of the opening and an opening position where the upper cover turns outward on an upper side of the casing and opens the upper side of the opening,
the upper cover has an upper wall covering the upper side of the opening in the closing position, and a lateral wall extending from an edge portion of the upper wall on a side of the lateral face of the casing along the lateral face of the casing in the closing position and covering a part of the lateral side of the opening,
the lateral cover has a fitting wall facing a rear face of the lateral wall of the upper cover when the upper cover is displaced from the opening position to the closing position in a state where the lateral cover is in the closing position, and
the image forming apparatus further comprises a closing position holding mechanism which holds the lateral cover in the closing position, wherein
the closing position holding mechanism includes an engaging part provided in the lateral wall of the upper cover and an engaged part provided in the fitting wall of the lateral cover,
when the upper cover is displaced from the opening position to the closing position in the state where the lateral cover is in the closing position, the engaging part of the upper cover is engaged with the engaged part of the lateral cover from an outside on the lateral side of the casing, and
when the upper cover is displaced from the closing position to the opening position in the state where the lateral cover is in the closing position, the engagement of the engaging part with the engaged part is released as the upper cover is displaced.
