Summary:PURPOSE:To facilitate switching of a color of a recording image by providing plural developer supply parts on each developing device. CONSTITUTION:According to this method, a first electrification processing is executed onto a photosensitive body 1, a first electrostatic latent image is formed, developed and a first toner image is formed, and thereafter, the second electrostatic latent image is formed, and developed by using a toner whose color is different from that of the first toner, and a first developing device 5 and a second developing device 6 are both provided with one developing roller 5a and 6a, and plural developer supply parts 5b-5d and 6b-6d, respectively, contain toners whose frictional electrification polarity is the same polarity and whose colors are different from each other, and in accordance with the contents of a recording image, a combination of colors of the toners of the first developing device 5 and a second developing device 6 is selected. In such a way, by selecting and combining the colors of the toners, a recording image of various color schemes is obtained.
