Abstract
An image forming apparatus for reading a document image, digitizing the resulting image data, and then forming an image on the basis of the digitized image data. The apparatus is selectively operable in an ordinary mode for reading the document image every time an image is formed or in a high-speed mode for writing the digitized image data in a memory so as to form a plurality of images by a single scanning while reducing the interval between consecutive papers. A fixing unit is provided with a higher reload temperature in the high-speed mode than in the ordinary mode. This obviates a cold offset in the event of a start-up when the high-speed mode is selected.
