Abstract: The present invention provides an image forming device including: plural image formation sections, a second exposure section, a transfer body, a reading section and an identification section. Each image formation section includes a control section that controls a first exposure section to form an identification image of a color represented by color information in accordance with an image formation instruction. The second exposure section performs exposure onto a charged image-bearing body and forms an electrostatic latent image. An image is formed at the transfer body. The reading section reads an image. The identification section outputs to the plurality of image formation sections an image formation instruction and, on the basis of a duration from the output until the identification image is read by the reading section, identifies a position of the image formation section forming the image of the color instructed by the image formation instruction.
