ABSTRACT:
A developing operation control device using an electro-developing recording medium on which an image is developed while an electric voltage is applied thereto. With starting the voltage application to the electro-developing medium, a voltage applied to a liquid crystal display included in the electro-developing recording medium is increased. When a predetermined time has passed since the voltage application to the electro-developing recording medium is started, an exposure onto the electro-developing recording medium is started. By starting the exposure, a bright portion occurs on the electro-developing recording medium, and the voltage applied to the bright portion of the liquid crystal display is quickly raised in comparison with a dark portion. The voltage application to the electro-developing recording medium is stopped at a predetermined timing.
