IMAGE FORMING APPARATUS AND CONTROLLING METHOD FOR IMAGE FORMING APPARATUS

摘要

An image forming apparatus is provided with a first photosensitive body, a second photosensitive body, a first charger configured to charge the first photosensitive body, a second charger configured to charge the second photosensitive body, a voltage outputting circuit, a voltage dropping circuit, and a controller. The controller is configured to selectively execute a first charging control to apply a first voltage to the first charger and the second charger, the first voltage being an output of the voltage outputting circuit, and a second charging control to apply the first voltage to the first charger a second voltage to the second charger, the second voltage being less than the first voltage, the first voltage being an input of the voltage dropping circuit and the second voltage being an output of the voltage dropping circuit.
