摘要： This invention provides a technique of preventing a collision between an original document and a printing material on a conveyance path when an image forming apparatus executes both additional printing on the original document and printing on the printing material. In a case where both additional printing on an original document and printing on a printing material are executed, the image forming apparatus according to one aspect of the invention conveys a read original document to a transfer unit through a conveyance path commonly used for an original document and sheet, and prints an image to be added on the original document. After the original document is conveyed to the transfer unit through the conveyance path, the image forming apparatus feeds a sheet from a sheet feeding unit to the conveyance path, and performs copying on the sheet in the transfer unit.
