ABSTRACT:
An image forming apparatus includes a conveying pipe configured to convey a developer and a magnetic field generation mechanism configured to generate a magnetic field inside the conveying pipe to affect the developer. The magnet is formed to have lower magnetic intensities at positions upstream and downstream from a middle position of the conveying pipe along a conveying direction of the conveying pipe than a magnetic intensity in the middle of the conveying pipe.
