PROBLEM TO BE SOLVED: To prevent developer from wastefully adhering to an image carrier even in the case of emergency stop in the middle of image producing process. SOLUTION: In the case of the emergency stop in the middle of the image producing process, a stop operation control means immediately stops electrifying operation by an electrifying means (timing (1)), moves the image carrier by amount equivalent to at least the length of the electrified area of the image carrier from an electrifying position by the electrifying means to a developing position by a developing means (timing (2) (3)), and the electrified area is prevented from passing through the developing position where the developing operation is stopped by stopping developing operation by the developing means and the moving operation of the image carrier, so that the developer is prevented from wastefully adhering to the surface of the image carrier in the case of the emergency stop and subsequent startup. |
