发明名称 Image forming apparatus
摘要 An image forming apparatus includes first and second image forming units respectively including first and second photosensitive members and first and second toner image forming devices for forming a toner image on the first and second photosensitive members respectively, and first and second transfer members configured to transfer the toner image formed on the first and second photosensitive members onto the belt member. The second image forming unit is arranged on a downstream side of the first image forming unit and is adjacent to the first image forming unit. An image forming apparatus further includes first and second photodischarging devices for discharging potential of the first and second photosensitive members respectively by irradiating thereon with light, wherein the first photodischarging device is turned off when the current is detected by applying the voltage to the second transfer member.
