摘要：
A clearance regulating amount L by a clearance regulating member 4, which is provided above a developing roller 3 on a side closer to a photosensitive drum 1, is determined at a size not greater than a height T of a developer at a magnetic pole just downstream of the clearance regulated position. Thus, the scattering of the developer from a developing unit 2 is significantly reduced.
