[Claims for Utility Model Registration] (1) An image forming apparatus that uses a developer made of magnetic toner and a magnetic carrier and is equipped with a developing device that has a rotating stirring member that stirs the developer. An image forming apparatus characterized in that the rotational speed of the rotary agitating member is decreased with increasing operating time. (2) A utility model characterized in that immediately after replenishing the magnetic toner into the developer, the rotation speed of the rotary stirring member is temporarily increased compared to the rotation speed of the rotary stirring member immediately before replenishment. An image forming apparatus according to claim 1.
