Abstract
In a developing device, a sheet member is provided via a gap at a second specific position in a specific region between a position on a downstream side in a first rotation direction relative to a first specific position, and a high-magnetic-force position at which an intensity of a magnetic force is the highest in a second region, on the outer circumferential surface of a developer carrying body. The sheet member limits a layer thickness of a two-component developer carried on the developer carrying body rotating in a second rotation direction. The sheet member is able to elastically deform in accordance with application of a pressing force equal to or greater than a tolerable value in the first rotation direction or the second rotation direction.
