摘要： An image forming apparatus comprises an image carrier which retains an electrostatic latent image corresponding to an original image, a developing device which sticks a toner to the electrostatic latent image to develop a toner image on the image carrier, an intermediate transferrer to which the toner image on the image carrier is transferred, a secondary transfer roller which transfers the toner image on the intermediate transferrer onto paper, and a cleaning member which cleans the secondary transfer roller. The secondary transfer roller can move to a first position to contact the intermediate transferrer, and to a second position to be separated from the intermediate transferrer, and the secondary transfer roller contacts the cleaning member at the second position.
