Abstract:
A developer carrier is provided in a rotatable manner. A layer-thickness control member makes a layer thickness of a developer carried on the developer carrier uniform. An accelerated agglomeration degree of the developer is equal to or less than 40%. The layer-thickness control member is formed with a blade. An angle between a rolling direction of the blade and a rotating direction of the developer carrier is set to 5 degrees to 80 degrees.
