ABSTRACT:
A lubricant applying unit has a residual-toner collection rate X of 50% when the lubricant applying unit has not been used. The collection rate X is obtained by X=(Ta−Tb)/Ta×100, where Ta is weight per unit area of the residual toner on an area of the image carrier that has not come into contact with the lubricant applying unit, and Tb is weight per unit area of the residual toner on an area of the image carrier that has come into contact with the lubricant applying unit.
