PURPOSE:To improve the resolution of a formed image by providing the titled device with a control means for controlling an erasing means in accordance with the operation of a specifying means and forming a frame around a material to be transferred carried by a carrying means. CONSTITUTION:When the depression of a frame-added specification key is discriminated by a main processor group after setting up an original along an original fixing scale and depressing the frame-added specification key, a distance from the corner part of an original G is specified by a spot light source, and if, e.g., the spot light source is moved to the position of Ga and a position specification key is depressed, the position (frame data) Fa of the frame speci fied by the position Ga is set up. Then, an erasing array 150 is controlled in accordance with the set frame data Fa and the frame is formed. Namely, a photosensitive drum 10 is driven under the state that an exposure lamp is kept at off, the erasing array 150 is selectively turned on in accordance with the frame data Fa and electrostatic charge on the part other than the frame data Fa is erased. Thus, an electrostatic latent image formed correspondingly to the frame data is developed by a developing device. |
