Abstract
A developing unit driving mechanism in use with a color image forming apparatus. The mechanism includes: a photoreceptor drum for holding plural color toner images which are developed from a latent image; plural developing units, disposed around the photoreceptor, each for developing the latent image; a driving motor, rotatable in the normal direction and the reverse direction, for driving the plural developing units; a planetary gear mechanism, including a sun gear and a planetary gear, for transmitting a driving force of the driving motor from the driving motor to a set of driven gears; and the set of driven gears, each for transmitting the driving force of the driving motor from the planetary gear mechanism to one of the plural developing units. In such a mechanism, the planetary gear is revolved on the sun gear in one direction so as to be connected with one of the set of driven gears when the driving motor rotates in the normal direction; and the planetary gear is revolved in the opposite direction, so as to be connected with other one of the set of driven gears when the driving motor rotates in the reverse direction. The planetary gear rotates on its axis for transmitting the driving force to a connected one of the driven gears.
