Patent ID: 6980309

Claim:
An image forming apparatus comprising: an input unit which inputs an image inputting condition of the apparatus; a scanner which reads a document on a basis of the image inputting condition input by the input unit and provides image data on the document as first image data; an image processing unit which processes the first image data provided by the scanner; a printer which forms an image on a sheet of paper corresponding to input image data processed by the image processing unit; an operating condition image producing unit which produces image data of a character string as second image data, indicative of operating conditions which determine image quality of the apparatus and include the image inputting condition input by the input unit; a synthesizing unit which synthesizes the first image data read by the scanner and processed by the image processing unit with the second image data produced by the operating condition image producing unit; a control unit which controls the printer to form an image corresponding to the first and second image data synthesized by the synthesizing unit on the sheet of paper; a designating unit which designates whether or not the first image data obtained by the image processing unit should be synthesized with the second image data produced by the operating condition image producing unit; and said synthesizing unit synthesizes the first image data obtained by the image processing unit with the second image data produced by the operating condition image producing unit and provides resultant synthesized image data in a case where the designating unit designates synthesis and provides only the first image data obtained by the image processing unit in other cases.
