ABSTRACT:
An image forming device includes an image support body on which an electrostatic latent image is formed. A developer develops the electrostatic latent image on the image support body with a toner to form a toner image. The toner image on the image support body is transferred to an intermediate transfer belt. A primary transferee transfers the toner image on the image support body onto the intermediate transfer belt, and a secondary transferee transfers the toner image on the intermediate transfer belt onto paper. The image support body and the primary transferee are offset. A volume resistance of the intermediate transfer belt is adjusted to a value within the range of 1×107to 1×1011Ω·cm and a surface resistance of the intermediate transfer belt is adjusted to a value within the range of 1×108to 1×1012Ω/□.
