摘要： An image forming apparatus includes an intermediate transfer body, a plurality of image bearers, a plurality of developing devices, a plurality of primary transfer devices, a secondary transfer device, and a cleaner. The plurality of image bearers is disposed side by side along the intermediate transfer body In a refreshing mode, the plurality of developing devices form toner images on the plurality of image bearers during a non-image-formation period and the cleaner cleans a surface of the intermediate transfer body. In the refreshing mode, a toner image formed on one image bearer of the plurality of image bearers, which differs from a most downstream image bearer of the plurality of image bearers in a direction of conveyance of the intermediate transfer body, reaches the cleaner first of the toner images formed on the plurality of image bearers.
