An image forming apparatus (10) capable of releasing pressure of toner accumulated between photoreceptor drums and cleaning blades without affecting the life of the photoreceptor drums includes photoreceptor drums (21A to 21D), an intermediate transfer belt (31), cleaning blades (250A to 250D), a cam mechanism (36), and a drive motor (26). The photoreceptor drums (21B to 21D) bear a toner image. The toner image is transferred from the photoreceptor drums (21A to 21D) to the intermediate transfer belt. The cleaning blades (250A to 250D) remove toner remaining on the photoreceptor drums (21A to 21D) after the toner image transfer. The cam mechanism (36) switches, after an image forming process, a contact state of the photoreceptor drums (21A to 21D) and the intermediate transfer belt (31) to a separation state. The drive motor (26) rotates the photoreceptor drums (21B to 21D) backward after switching the contact state to the separation state. |
