PURPOSE:To obtain a small-sized and inexpensive image forming device capable of obtaining a full color image by providing a color separation filter having complementary color relation to the color of developer contained in an attachable/detachable developing device and constituting so that the color separation filter may be positioned in the optical path for image exposure when it is attached to a device main body. CONSTITUTION:In a developing means 6, toner in a toner reservoir 6a s fed by a toner feeding member 6b, a developing sleeve 6d incorporating a fixed magnet 6c is rotated, and a toner layer to which triboelectrifying charge is applied is formed on the sleeve 6d by a developing blade 6e and the toner is transferred to a photoreceptor drum 1 in accordance with a latent image, whereby a toner image is formed and visualized. The developing means 6 is integrally provided with the color separation filter 5 having the complementary color relation to the toner contained in the toner reservoir 6a and constituted to be interchangeable to the device main body A. The filter 5 is disposed to be positioned in the optical path of the image exposure when the means 6 is attached to the device main body A. |
