PURPOSE:To enable image processing in proper density by providing a changeover means between the case of an ordinary original and a reflective type display, and even in the case of a reflective type original, providing a means for controlling image processing density in a scale same as in the case of an ordinary original. CONSTITUTION:A photosensitive drum 1 is rotated in the direction of an arrow 2, and a light source 3 and mirrors 4, 5 are moved in the direction of an arrow 6 to expose the drum 1 to the light image of an original 8. On the other hand, the drum 1 is destaticized with a destaticization charger 11 and the surface is electrostatically charged with a primary charger 13. The drum 1 is reversely charged with a secondary charger 14 and at the same time, said exposure is made by illuminating the surface of the drum 1 with a lamp 15 to form an electrostatic latent image on the surface. It is developed to form a toner image with a developing device 16, and it is transferred to a paper with a transfer charger 17 when it passes between the drum 1 and charger 17. The transferred toner image is fixed to the paper when it passes through a fixing device 18. Image density of a copoied image can be controlled by moving a lever 19 to a proper position in accordance with original density on an operational panel. |
