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.

Claim (Index 3):
The image forming apparatus according to  claim 2  further comprising:\n a toner container containing the toner replenished to the developing device; and \n a waste toner box collecting the waste toner removed by the cleaning blade, \n wherein in the turning-up restraining process, on the basis of the average printing rate, a first consumption amount of the toner consumed per sheet with respect to the cumulative printing number of developing process is calculated, \n on the basis of the multiplying factor in a case where the variable is set to a maximum value, a second consumption amount of the toner consumed per sheet with respect to the turning-up restraining process is calculated, \n a total consumption amount of the toner consumed per sheet is calculated by adding the first consumption amount and the second consumption amount, \n a total printing number of sheets printable by a whole toner amount of the toner container in a case where the developing process and the turning-up restraining process are repeated by using the total consumption amount is calculated, \n on the basis of the total consumption amount, a collecting amount of the waste toner collected in the waste toner box per sheet is calculated, \n on the basis of the collecting amount and the total printing number, a total collecting amount of the waste toner collected in the waste toner box with respect to the whole toner amount of the toner container is calculated, \n in a case where the total collecting amount exceeds a capacity or a safety amount of the waste toner box, the variable is recalculated by subtracting a predetermined value and the toner feeding amount is recalculated by using the recalculated variable.
