Abstract
An image forming apparatus includes an image carrier carrying a toner image, a developing device, and a cleaning blade. The developing device carries out developing process feeding toner to the image carrier during image forming. The cleaning blade comes into contact with the image carrier and removes waste toner remained on the image carrier. In order to restrain turning-up of the cleaning blade, turning-up restraining process is carried out to feed the toner from the developing device to the image carrier during non-image forming, every time a given cumulative printing number of image forming operation is finished. In the turning-up restraining process, larger toner is fed to the image carrier as a given small size printing number in the cumulative printing number becomes larger.
