ABSTRACT:
A color image-forming apparatus comprises an electrophotoconductive imaging member moving in a first direction. A first corona charger forms an electrostatic charge on the imaging member. A first exposure device such as a laser or LED printhead imagewise modulates the electrostatic charge on an area of the member comprising an image frame. A first developer station develops a first visible image on the image frame with a pigmented toner of a first color. A second corona charger electrostatically charges the image frame having the visible image. A second exposure device such as a laser or LED device imagewise modulates the electrostatic charge on the image frame that was formed by the second charger. A second visible image is then formed on the image frame with a pigmented toner of a second color. The first and second visible images are transferred to a surface of a receiver sheet to form a two-colored image thereon. One of said first and second exposure devices is a raster printer that records rasterized lines of image data in a direction transverse to the first direction. The raster printing includes means for storing data representing bow error in printing of a raster line. Printing is done in response to image data and bow error data for recording substantially straight raster lines of image dam.
