ABSTRACT:
A voltage switch for connecting a power supply with a plurality of development units in sequence, and an electrophotographic color image forming apparatus using the voltage switch. In the voltage switch, a first terminal is arranged on a circuit board and is connected to the power supply, and a plurality of second terminals are arranged in a circle on the circuit board and are connected with the plurality of development units, respectively. A rotor is rotatably coupled with the circuit board of the switch and is provided with a lead, such that as the rotor rotates about the circle, the first terminal can be electrically connected with the plurality of second terminals in sequence.
