ABSTRACT:
When the present image forming apparatus is used as a network scanner configured to read a document and forward corresponding image data to a network, delay memories M, C, K allow RGB image data supplied from the scanner to be delayed by an equal time. A specific document detecting section decides whether or not any document image read by the scanner is a specific document and, if it is a specific document, provides a specific document detection signal SOD to a selector. In response to this signal, the selector selects mask data from a mask data retaining section in place of the RGB image data and outputs the mask data. Thus, it is possible to prevent the specific document image data from being transmitted through the network to an external device.
