像形成装置。 Color-separated light images are formed on multiple photoreceptor belts, and the images are visualized using toner of a color corresponding to each light image.
In a color image forming apparatus that sequentially transfers the color toner images from each photoreceptor belt onto a transfer material conveyed onto a transfer belt, the distance between the exposure position and the transfer position on each photoreceptor belt, and the distance between each transfer The distance between the positions is an integral multiple of the diameter of the drive roller of each photoreceptor belt and the transfer belt, the material and shape of the drive rollers are the same, and the coefficient of linear expansion in the diametrical direction of each drive roller is the same. color image forming device.
