Patent ID: 7702266

Claim:
An image forming apparatus provided with a one-component development apparatus having a toner layer regulating blade for regulating a thickness of a toner layer on a surface of a developer bearing member that contacts a photosensitive body, wherein at a non-development time after completion of operation of the developer bearing member, the developer bearing member is caused to rotate slightly in a direction reverse to that during development and the photosensitive body is also caused to simultaneously rotate in reverse when the developer bearing member is caused to rotate in reverse, wherein a toner scattering prevention sheet is provided such that a tip end thereof contacts a surface of the photosensitive body, near an opening of a development tank that accommodates the developer bearing member, and wherein a movement distance of the surface of the developer bearing member at a time of reverse rotation is within a range from a position at a time of development stoppage to immediately prior to where the toner scattering prevention sheet that contacts the photosensitive body goes into a non-contact state with the photosensitive body.
