PURPOSE:To execute the editing-copying by providing a means for detecting a color of a toner of a developing device, and a correction mode control means for setting a correction mode at the time of having a white toner and inhibiting an optical image projection with respect to an exposure scanning means. CONSTITUTION:By operating a key of an editor 900, an editing copying mode and a color are selected and a square editing-copying area on a tablet is designated by a touch pen. A CPU 621 allows various operations to synchronize mutually, a CPU 622 receives coordinate information from the editor through an A/D converter, and LEDs being in one line of an eraser 4 which is placed adjacently to a photosensitive drum are brought to light emission selectively, by which a charge is eliminated. By a color selection key of the editor, a toner color is selected and a CPU 623 controls various operations of an exposure scan of an optical system, and when a developing machine has a white toner, a correction mode is set and a projection inhibition of an optical image is commanded to an exposure operating means. According to this constitution, a correction mode selecting switch becomes unnecessary, and by only controlling the eraser, a solid image used for a correction can be formed. |
