Arrangement of operation unit in image forming apparatus

An image forming apparatus comprising:

• an image reading device that reads a document;
• an image forming unit that is provided below the image reading device, and forms an image on a sheet;
• a supporting member that is provided between the image reading device and the image forming unit in a height direction of the image forming apparatus, and supports the image reading device disposed above the image forming unit;
• a stacking unit that is provided between the image reading device and the image forming unit in the height direction of the image forming apparatus, and is disposed adjacent to the supporting member, and on which the sheet discharged from the image forming unit is stacked;
• a discharge unit that is provided in the image forming unit, and is configured to discharge the sheet from the image forming unit to the stacking unit;
• and
• an operation unit that is configured to accept input for operating at least one of the image forming unit and the image reading device, and is supported by the image reading device, on a front side of the image forming apparatus,
• wherein the supporting member supports the image reading device such that the image reading device is movable between a first position at which a front side of the image reading device is close to the image forming unit and a second position at which the front side of the image reading device is spaced apart from the image forming unit,
• a first end portion of the operation unit protrudes outward of the image forming unit from one side surface of the image forming unit, in a width direction of the image forming apparatus, and
• a second end portion of the operation unit that opposes the first end portion is positioned on an inner side of the image forming unit relative to the one side surface of the image forming unit, in the width direction of the image forming apparatus.
