Abstract
The CPU of the image forming apparatus sets up an ADF reading magnification in the ADF driving unit including the motor and the motor driver referring to the first magnification conversion table in the memory of the system unit when reading a document image while a document is being moved. Further, the reading magnification that is also in the ADF driving unit is also set in the specific document detection unit. The specific document detection unit makes the pattern matching as to whether the read image data is that of a specific document using the magnification dictionary (specific image data) that is set and outputs a detection signal as the result of the matching to the CPU. As that time, the CPU controls the output of the applicable read image data by a printer according to the detection signal.
