Abstract
An image forming apparatus includes an image former and a hardware processor. The image former includes, an image carrier; a developer; a conductive rotating member; and a voltage applier which applies voltage to the rotating member. The hardware processor executes an attached material detection mode which detects material attached to a surface of the rotating member. In such mode, the hardware processor controls the voltage so that the developing bias is a value between a surface potential in a region of the image carrier in contact with a portion in which attached material exists on a surface of the rotating member if a reference voltage is applied by the voltage applier, and a surface potential in a region of the image carrier in contact with a portion in which the attached material does not exist on the surface of the rotating member if the reference voltage is applied.
