An image forming apparatus comprises: a photosensitive member which is capable of carrying an electrostatic latent image and rotates in a predetermined direction; a developer which visualizes with toner the electrostatic latent image carried on the photosensitive member and forms a toner image; an intermediate transfer member which temporarily carries the toner image transferred from the photosensitive member; a photosensitive member cleaner which abuts on a surface of the photosensitive member and removes toner adhering on the photosensitive member; an intermediate transfer member cleaner which abuts on a surface of the intermediate transfer member and removes toner adhering on the intermediate transfer member; and a controller which executes toner accumulating processing during which a toner-accumulating patch image including a predetermined first area and a predetermined second area is formed on the photosensitive member, toner in the first area is transferred onto the intermediate transfer member and the intermediate transfer member cleaner removes the toner, thereby accumulating the toner in an abutting section between the intermediate transfer member and the intermediate transfer member cleaner, while the photosensitive member cleaner removes toner in the second area, thereby accumulating the toner in an abutting section between the photosensitive member and the photosensitive member cleaner, wherein the first area is formed in a different surface area within the surface of the photosensitive member from an area in which the second area is created during an immediately preceding rotation of the photosensitive member.
