Abstract
A cleaning device has a plurality of cleaning blades capable of coming into contact with an image carrier; a rotatable supporting shaft on which the blades are affixed; and a blade replacement mechanism that rotates the supporting shaft and thereby replaces the blade that is in contact with the image carrier with another blade by rotating the supporting shaft. The blade replacement mechanism includes a supporting shaft mover for moving a blade between a position in which the blade comes into pressure contact with the image carrier and a position in which the blade separated from the image carrier; a moving controller connected with the supporting shaft mover; and a rotator for rotating the blade supporting shaft when the blade takes a position in which the blade separates from the image carrier.
