色画像形成装置。[Claims for Utility Model Registration] (1) A bipolar photoconductor is primarily charged to a predetermined polarity, and then a first exposure is performed to form a first electrostatic latent image; Development is performed using a peripheral effect developing means with a strong peripheral effect, and then secondary charging is performed with a polarity opposite to the primary charging, followed by further development of the first electrostatic latent image by the first developing means or second exposure. A two-color image forming apparatus characterized in that either one of the steps of forming the second electrostatic latent image is performed first, and after both are completed, the twelfth electrostatic latent image is developed in the second developing means. (2) The developer attached to the bipolar photoreceptor due to the development by the peripheral effect developing means is removed by the removing means, and the first electrostatic latent image is developed by the first developing means or the second electrostatic latent image is developed by the second exposure. Utility model registration claim 1, characterized in that either one of the two electrostatic latent images is formed first, and after both are completed, the second electrostatic latent image is developed by the second developing means. 2 mentioned
Color image forming device.
