An image forming apparatus having an image carrier, a document table on which a document is placed, and a document feeder associated with the document table for feeding and document onto the document table, the document feeder including a document carrier for carrying the document and a designating unit for designating an image blanking range of the document placed on the document carrier. The image forming apparatus also includes an optical scanning unit for optically scanning the document fed onto the document table from the document feeder and for forming a reflected light image thereof, a first image forming unit for forming an electrostatic latent image corresponding to the light image onto the image carrier, a second image forming unit for producing a visible image on an image forming medium corresponding to the electrostatic latent image, an image blanking unit for selectively blanking a selected portion corresponding to the image blanking range designated by the designating unit of the electrostatic latent image formed by the first image forming unit, and a controller for controlling the image blanking unit to erase the electrostatic latent image corresponding to the blanking range. The apparatus permits images to be formed by designation of portions of the document for which an image is to be formed and blanks unnecessary portions, the designation being carried out on the document feeder where the document is placed for automatic feeding.
