Abstract
A developer supplying apparatus can include a first chamber and a second chamber defined within a housing. Each of the first and second chambers may include an agitator disposed therein. A magnetic body may be disposed near the first chamber to receive toner from the first chamber. A controller can determine the level of developer received in the first chamber, and to based on the determined developer level control the operations of one or more of the agitators and the magnetic body in order to ensure sufficient supply of the developer in the first chamber to reduce the occurrences of image defects, such as, for example, auger marks.
