PROBLEM TO BE SOLVED: To provide an image forming apparatus having a developing means which vibrates a developing blade 46 to thereby remove foreign matter, the image forming apparatus capable of suppressing a deterioration in an image and flying of a developer. SOLUTION: The image forming apparatus forms an image by developing an electrostatic image formed on a photoreceptor drum 1 by the developer. The image forming apparatus is characterized in that it includes: a developing means which has a rotatable developing sleeve 44 and the developing blade 46 for restricting a developer layer borne on the developing sleeve 44, and develops the electrostatic image formed on the photoreceptor drum 1 by the developer; a vibrating means 50 for vibrating the developing blade 46; and a control means for controlling a drive condition of the vibrating means 50 according to a printing ratio of the formed image.
