ABSTRACT:
An image forming apparatus having an overall original-copy recording function for effecting image recording automatically in one simple operation without loss of any part of the overall original image. A scanner is used to scan an original copy to detect the original-copy size. In the absence of an original-copy skew, the original-copy size is assumed to be equal in size to the original image, whereas in the presence of the original-copy skew, the size of a square internally touched by the skewed original copy is made the original image. Selection is made of copying paper whose size is greater than a combination of the detected original-copy size and a copying paper skew and of a memory corresponding to the selected copying paper size, so that the original image that has been read is stored. The original image is formed on the selected copying paper before being output. Through the above process, loss of any part of the image is prevented by providing a margin greater than the copying paper skew quantity between the copying paper edge portion and the original image.
