Abstract
PURPOSE:To attain high speed processing in which the quality of an image is excellent, by installing a moving means for making a two-dimensional exposing device move in the moving direction of a photosensitive body at the same speed in case of exposure and a returning means for making the two-dimensional exposing device return in the direction opposite to the moving direction of the photosensitive body after completing the exposure. CONSTITUTION:The photosensitive body on the upper surface of an end-less belt 2 is uniformly electrified by an electrostatic charger 5 and moves to a downstream side to be an exposed surface 3. When the exposed surface 3 is exposed in terms of two-dimensional pattern by the two-dimensional exposing device, 4, the device 4 moves to the downstream side with the exposed surface 3 at the same speed by a specified distance by means of a driving device. Then, sufficient exposure can be obtained even if the moving speed of the endless belt 2 is high. When the two-dimensional exposing device 4 moves by the specified distance and completes the exposure, it is made to return to an original position again by means of the driving device. Even if the photosensitive body is made to always move at a constant speed, the constant speed can be made high, and the quality of the image does not receive adverse effects.
