An image forming apparatus includes an image carrier, a latent image forming device, a developer, an intermediate transfer belt, a second transfer device, a cleaner, an abutting angle adjuster and a hardware processor. The intermediate transfer belt supports and carries a toner image which is transferred from the image carrier by primary transfer. The second transfer device performs secondary transfer to transfer the toner image transferred on the intermediate transfer belt to a recording medium. The cleaner abuts the intermediate transfer belt to remove toner attached to a surface of the intermediate transfer belt. The abutting angle adjuster adjusts an abutting angle between the cleaner and the intermediate transfer belt. The hardware processor controls the abutting angle adjuster to maintain the abutting angle at a predetermined angle.
