Abstract: An image forming apparatus includes an image carrier; a charger that electrically charges the image carrier; an image forming section that forms an electrostatic latent image on the image carrier and develops the electrostatic latent image; a transferring-fixing section that transfers the image from the image carrier and fix the image onto a recording medium; a cleaning member; and a cleaning member moving section. The cleaning member cleans an unnecessary substance adhering onto a surface of the image carrier by abutting against the surface of the image carrier, and is capable of moving between an abutment position and a separation position where the cleaning member is separated from the image carrier. The cleaning member moving section moves the cleaning member from the separation position to the abutment position in accordance with a surface resistance of the surface of the image carrier.
