An imaging apparatus is provided, including a blade-driving device and a driving control unit which drives the front curtain actuator and the rear curtain actuator. The front curtain and the rear curtain are positioned at the open position at a time of start and termination of imaging, in which the front curtain moves from the closing position to the open position, and the rear curtain moves from the open position to the closing position, thereby performing an exposure operation. During consecutive photographing, the front curtain positioned at the closing position is moved once in a direction of the open position and is then returned to the closing position after the rear curtain is moved to the open position after termination of the exposure operation, and before a subsequent exposure operation is performed.
