Abstract:
An image processing device, comprising:an image data input device that inputs image data representing an image; a photoreceptor belt; a plurality of image forming stations arranged along the photoreceptor belt, each image forming station forming an image from the image data; a plurality of first sensors provided along the edge of the photoreceptor belt, each sensor outputting a first sensor signal; a skew determining circuit that determines an amount of skew of the photoreceptor belt based on the first sensor signals; at least one set of second sensors provided along the surface of the photoreceptor belt, each second sensor outputting a second sensor signal; a direct registration determining circuit that determines registration offsets between the formed images based on the second sensor signals; and a registration adjusting circuit that controls formation of images by at least one of the image forming stations based on the image data and the determined amount of skew in a first mode, and based on the image data and the determined registration offsets in a second mode.
