Abstract:
An image forming apparatus includes an image carrier carrying a toner image, a developing device carrying out developing process feeding toner to the image carrier during image forming, and a cleaning blade coming into contact with the image carrier and removing waste toner on the image carrier. Turning-up restraining process feeds the toner of a constant feeding amount from the developing device to the image carrier. Replacing process feeds the toner of a variation feeding amount according to an average printing rate 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, the replacing process is carried out in a case where the variation feeding amount according to the average printing rate in the cumulative printing number of developing process exceeds the constant feeding amount, but the turning-up restraining process is carried out otherwise.

Claim (Index 1):
An image forming apparatus comprising:\n an image carrier carrying a toner image; a developing device carrying out developing process feeding toner to the image carrier during image forming; and a cleaning blade coming into contact with the image carrier and removing waste toner remained on the image carrier, wherein the image forming apparatus is configured to carry out, in order to restrain turning-up of the cleaning blade, turning-up restraining process feeding the toner of a constant feeding amount from the developing device to the image carrier, and to carry out, in order to replace the toner stored in the developing device, replacing process feeding the toner of a variation feeding amount according to an average printing rate 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, the replacing process is carried out in a case where the variation feeding amount according to the average printing rate in the cumulative printing number of developing process exceeds the constant feeding amount, but the turning-up restraining process is carried out otherwise.
