PURPOSE:To easily and surely confirm the fatigue of a photosensitive body whether the photosensitive body is independently placed or is set to an image forming device by grounding the base body of the photosensitive body through an integral power supply quantity detecting member to display the fatigue of the photosensitive body. CONSTITUTION:A photosensitive body fatigue detector 2 is provided with an insulating supporting frame 3, a conductive supporting member 4 supported by the frame 3, and a fatigue meter 5 attached to the frame 3, and the fatigue meter 5 consists of an instrument capable of detecting the integral power supply quantity and is provided with a terminal 5a connected to the supporting member 4 and a ground terminal 5b. A current successively passes a base body 1a of a photosensitive body 1 and the fatigue meter 5 and is grounded by the voltage applied from a power source 9, and the extent of fatigue of the photosensitive body 1 is detected by the power supply quantity in this case. Thus, the fatigue of the photosensitive body 1 is easily confirmed whether the photosensitive body 1 is independently placed or is built in the image forming device. |
