ABSTRACT:
An image forming apparatus is provided which includes a document set section, a document size detecting device, a medium set section, a device for picking up the size of the medium, a medium feed device, and an image forming device for forming an image of a document in the document set section on the medium of an image forming location. The apparatus further includes an auto magnification designating device for generating data to designate an image forming magnification according to data representative of the size of the medium picked up by the pick up device by using the document size as detected by the document size detecting device. Further, a manual magnification designating device is providing for manually designating a desired magnification for image forming. A first priority means for operating the auto magnification designating device to define a first default mode of operation of the apparatus and a second priority means for operating the manual magnification designating means for defining a second default mode of operation of the image forming device are also provided. Finally, a priority select device is provided for reversibly selecting between the first and second priority means so as to select a default mode of operation of the apparatus.
