Abstract: Primary scanning or other operation is not required by the light source of an internal exposure method, significantly improving the positioning of each color. An EL pixel array 134 is affixed as internal light source 124 to the entire surface of a photoconductive drum 114, and pixels controllable by TFT layer 144 are allocated to the entire image formation area of the photoconductive drum 114. Unlike with a conventional internal light source using an LED, a mechanism for moving in a primary scanning direction is therefore not needed and elements whereby the position of each color image shift are completely eliminated. As a result, there is absolutely no color shifting in full color images, and high quality images can be obtained.
