Developer driving apparatus and image forming apparatus including the same
First Claim
1. A developer driving apparatus for an image forming apparatus, which selectively operates a plurality of developers to develop an electrostatic latent image formed on a photosensitive body with a predetermined color, the developer driving apparatus comprising:
- a driving source;
a power transmitting unit selectively transmitting power generated by the driving source to development rollers of the developers to drive the developers; and
a power controlling unit provided between the driving source and the power transmitting unit and controlling the power so that the power is transmitted to the corresponding developer.

Abstract
A developer driving apparatus and an image forming apparatus including the developer driving apparatus are provided. The developer driving apparatus includes a driving source; a power transmitting unit, and a power controlling unit. The power transmitting unit selectively transmits power generated by the driving source to development rollers of the developers to drive the developers. The power controlling unit is provided between the driving source and the power transmitting unit and controls the power so that the power is transmitted to the corresponding developer. Accordingly, the plurality of the drive developers can be driven using two power controlling units, that is, two electronic clutches, unlike conventional apparatuses that use four electronic clutches. Accordingly, the manufacturing cost of the image forming apparatus can be reduced. Also, the number of the power controlling units can be reduced and the space occupied by the power controlling units can be reduced. Thus, the developer driving apparatus and the image forming apparatus can be made more compact.
