Abstract
A rotary developing apparatus having a plurality of developing devices mounted along the outer periphery of a cylindrical rotary unit. A first gear train for connecting the rotary unit to a drive source to rotate the rotary unit. A second gear train for connecting a developing roller of a developing device revolved and stopped at a developing position, as a result of the rotary unit being rotationally driven, to the drive source to rotate the developing roller. The rotary unit and the developing roller are rotated with the same motor used as the drive source by switching between the connections of the gear trains, thereby rapidly damping vibration generated by the rotation of the rotary unit and vibration generated by the rotation of the developing roller, and thus eliminating image defects due to displacement, etc.
