摘要： An image forming apparatus includes a plurality of motors, a controller which generates control signals to control the plurality of motors and output the control signals, and a plurality of motor drivers which control corresponding motors among the plurality of motors if the enable signal among the control signal is input, and does not control the motors although the common signal is input if the enable signal is not input. Accordingly, the image forming apparatus may control a plurality of motors which is not necessary to be driven at the same time using an enable signal and thus the motors may be effectively controlled with low expense.
