Abstract
A contact time with an image carrier and a cleaning blade is added up, and a toner image pattern is formed according to such an added up value. Accordingly, the quantity of toner as a lubricant sticking based on a toner image pattern becomes a most suitable quantity. As the added up value increases when it is described concretely, an area of the toner image pattern is made small, and accordingly a quantity of adhesion of toner is reduced. Accordingly, when a frictional resistance between an image carrier and a cleaning blade becomes low, or when an image carrier deteriorates, a quantity of supply of toner is controlled to be a proper amount
