PROBLEM TO BE SOLVED: To avoid problems such as an enlargement of a device, an increase in cost, an increase in weight of the device, the reduction of the design freedom, or the like, without making a user visually recognize an image slippage derived from the drive irregularity of the image carrier, in an image forming device provided with plural image carriers. SOLUTION: This is an image forming device performing the image formation by respectively forming the developer image of a specified color on plural image carriers 1a to 1d being arranged, and laminating plural positive image of the specific color developer corresponding to plural image carriers 1a to 1d on recording medium. In this case, the end parts of rotary shafts of plural image carriers 1a to 1c adaptable to color material with high visibility are respectively provided with flywheel 3a to 3c, while the image carrier 1d adaptable to the color material with the relatively lower visibility is not provided with the flywheel 3d, or provided with the flywheel 3d with the different size or weight, so that the inertia condition is set different from other image carriers 1a to 1c. |
