Summary:PROBLEM TO BE SOLVED: To make a rotation shaft and a film strongly related, and to enable toner to be fed over a long period by making a film of an agitator by insert formation. SOLUTION: This device rotates a gear connected with a shaft main body (agitator shaft) 2 of the agitator side by the drive of a motor 6, and simultaneously rotates a magnet roller 1. The shaft main body 2 is provided with a function scraping up and agitating the toner 5 in the toner container 4, while rotating. The toner 5 in the toner container 4 is agitated by the film 3 of the agitator, transferred, fed on the magnet roller 1, and fed into the developing device by the magnet roller 1 and a scraping member 7. The film 3, being the film of an approximately rectangular as a whole and the leading end thereof is held in contact with an inner peripheral surface of the toner container 4. Moreover, this film 3 is fixed to the shaft main body 2 by the insert formation at the side opposite to the side being held in contact with the toner container 4 inner peripheral surface. Therefore, the film is prevented from peeling off from the rotary shaft.
