An image forming apparatus configured to form an image on a recording medium. The image forming apparatus includes an optical sensor disposed on a conveyance path of the recording medium. The optical sensor is configured to detect position information of the recording medium conveyed along the conveyance path. A sensor cover is disposed between the optical sensor and the recording medium whose position information is detected by the optical sensor. The sensor cover is configured to guide the recording medium. The sensor cover has a first side facing the optical sensor. The sensor cover includes an electrically conductive surface on the first side. The electrically conductive surface is electrically connected to a main body of the image forming apparatus.
