PURPOSE:To obtain a satisfactory picture quality copy where back-copying is not executed and a toner stain, a black frame, etc., are not found at the non-picture image part when the double faces copying is executed by preventing to form a static latent image at the non-picture image part of the image holding body and constituting the pressing surface of the original pressing member to a light absorption characteristic. CONSTITUTION:Since the pressing surface of an original pressing plate 15 is colored to gray or black having the reflecting density of about 0.2-2.0, when the double faces original is copied, the copying-in of the printing at the rear face is not executed, and a satisfactory picture can be obtained. A deleting lamp 4 of the light source for deleting the latent image is operated in accordance with the size and variable power ratio of the original, when the paper larger than the original size is used, the toner stain, a black frame, etc., will not occur at the non-picture image part, and a satisfactory picture quality copy can be obtained.
