According to an embodiment, an image shift can be decreased by a photoconductor belt which has a photosensitive layer formed on the surface of a cylindrically formed belt, a pair of rollers which is placed to apply tension to a photoconductor belt, and rotates the photoconductor belt in a specified direction, a charger which is placed opposite to the surface of the photoconductor belt placed between the pair of rollers, and charges the photosensitive layer, a light source which forms a latent image on the charged photosensitive layer, a developing unit which supplies a developing solution to the photosensitive layer having a latent image, develop the latent image, and forms a toner image, and an absorbing roller which is placed on the backside of the photoconductor belt placed between a pair of rollers, and absorbs the photoconductor belt.
