Abstract
In the exposing apparatus of an image forming apparatus or the like, an apparatus for suppressing the vibration of an optical part has a detector for detecting the vibrating state of the optical part, and a controller for controlling a vibrator so as to give the optical part such an appropriate amount of vibration as will negate the vibration of the optical part. Thereby, it becomes unnecessary to excessively increase the rigidity of the optical part and thus, a decrease in weight can be achieved.
