An image forming apparatus includes a scanner device and an image forming apparatus body to which the scanner device is attached. The scanner device has a document inlet and a document outlet respectively formed in mutually opposed surfaces thereof, and is configured to read an image of a document fed thereinto through the document inlet and discharge the document through the document outlet. The scanner device is detachably attached to a top surface of the image forming apparatus body. The top surface of the image forming apparatus body functions as a guide surface guiding the document when the scanner device is used.
