An object of the present invention is to detect the AC charging current accurately and uniformly charge the photosensitive member without being affected by the environment and stray capacitance due to the winding of the charging cable, etc., so that the photosensitive member is filmed over time. It is an object of the present invention to provide an image forming apparatus that is not generated. At least a photosensitive member, a charging device that charges the surface of the photosensitive member with an alternating current bias voltage superimposed on a direct current bias voltage as a charging bias voltage, and an alternating current that flows through the photosensitive member when the charging bias voltage is applied. AC current detecting means 313 for detecting, developing device for supplying toner to the latent image formed on the surface of the photosensitive member 1 to make it visible, and transfer device for transferring the visible image on the surface of the photosensitive member 1 to a transfer medium In the image forming apparatus comprising: a cleaning device that cleans the surface of the photoreceptor after the transfer; and a lubricant application device that applies a lubricant to the surface of the photoreceptor 1, the alternating current detection unit 313 generates an alternating current from the photoreceptor 1. It is detected on the ground side. [Selection] Figure 4 |
