An image forming device has plural photoreceptor drums on which a latent image is formed, wherein one of the photoreceptor drum is different diameter from the other photoreceptors. A belt in contact with the plural photoreceptor drums and plural transfer rollers press the photoreceptor drums from a side of the belt, the side being opposite to the side contacts with the photoreceptor, wherein a distance from a contact reference position. The contact reference position at which the photoreceptor contacts with the belt, to a pressed position of the transfer roller of a large-diameter photoreceptor drum is greater than that of a small-diameter photoreceptor drum.
