PROBLEM TO BE SOLVED: To provide an inexpensive image forming device which can be attached to an optional position without restricting the attaching positions of respective color developing devices and can form on image high in quality. SOLUTION: Plural developing devices 10A, 10B, 10C and 10D storing different color developer, respectively, develop an electrostatic latent image formed on the surface of a photoreceptor 1 so as to form a toner image for discriminating developer color of every color on the surface of the photoreceptor 1. The device is provided with a developer color detecting means 12 near the surface of the photoreceptor 1, and the means 12 detects the color of the toner image for discriminating the developer color of every color formed on the surface of the photoreceptor 1. A developer color information storage means 18 stores the detected color information, and an image printing condition control means 14 controls the image printing condition of the toner image for an image based on previously decided image printing order information and the stored color information. |
