PURPOSE:To simplify the constitution of a power source part and to improve the workability of assembling and exchanging by providing a combined power source body that a high voltage power source part and a low voltage power source part are housed in an identical housing body. CONSTITUTION:In the combined power source body 23, the low voltage power source part 24, a high voltage power source for electrostatic charge 38, a high voltage power source for transfer 39 and a high voltage power source for developing bias 40 are housed. An AC input from an AC inlet 25 is supplied to a low and constant voltage circuit 29 and a heater control part 32. DC low voltages (+5V, +12V and +24V) are generated by the circuit 29. Then, the voltages of +5V and +12V are immediately outputted to a first connector 31 and the voltage of +24V is supplied to the first connector 31, an output connector for a fan motor 37 and the power sources 38, 39 and 40 through an interlock switch 30. Due to that, the high voltage power source and the low voltage power source can be connected without requiring a harness. Besides, the assembling and the exchanging of the power source with respect to a device main body are facilitated. |
