摘要： An operation unit is provided on a front side of the image forming apparatus. A document feeding portion feeds a document supported by a document supporting portion in a document feeding direction from a front side of the image forming apparatus toward the rear side of the image forming apparatus. A document discharge portion discharges the document in a document discharge direction from the rear side toward the front side. The operation unit is disposed on one side with respect to an apparatus center of the image forming apparatus in a left-right direction orthogonal to a direction from the front side to the rear side. A conveyance center of the document feeding portion in the left-right direction is disposed on the other side with respect to the apparatus center in the left-right direction.

摘要： A document supporting portion includes a first supporting portion and a second supporting portion. The first supporting portion has a first supporting surface that supports a document. The second supporting portion has a second supporting surface that supports the document together with the first supporting surface and provided so as to be slidable between a first position at which the second supporting portion located above the first supporting portion and a second position at which the second supporting surface supports the document together with the first supporting surface. In a state where the second supporting portion is located at the first position, the second supporting surface constitutes a portion of an upper surface of the document feeding apparatus.
