An image fluctuation correcting apparatus rotates a first rotary apex angle prism held in a first prism holding member around a first shaft in a direction for canceling an amount of horizontal fluctuation by electromagnetic force generated between a first drive coil and a first magnet by flowing electric current in the first drive coil. Also, the image fluctuation correcting apparatus rotates a second rotary apex angle prism held in a second prism holding member around a second shaft, which is located 180-degree angle away from the first shaft, in a direction for canceling an amount of vertical fluctuation by electromagnetic force generated between a second drive coil and a second magnet by flowing electric current in the second drive coil.
