Abstract: An image forming apparatus is capable of scanning a document having a larger size than the flat. For example, it is possible to scan an A3 document using a scanning sensor having a slight larger size than an A4 document, and also it is possible to obtain a high quality of the A3 document image.

Abstract: An A4-size scanner capable of scanning an A3 document. The A4-size scanner includes a scanning part, a transferring roller member that is disposed at an upper side of the flat glass to be orthogonal to a length direction of the automatic document feeding unit and the scanning sensor so that the document having a double size of a scanning capacity of the scanning sensor and introduced onto the flat glass in the length direction of the automatic document feeding unit and the scanning sensor is transferred to a transferring roller, and a transferring roller member driving motor that is connected with the transferring roller which dividedly scans the document having a larger size than the scanning capacity of the scanning sensor; and an image processing part which performs an image processing for composing two images which are dividedly scanned through the scanning part.
