Abstract
A developing apparatus for supplying a developer to a photoreceptor so that an electrostatic latent image on the photoreceptor is developed with the developer. The developing apparatus comprises a developer conveyer, having a rigid surface, for conveying the developer to a developing zone; a developer layer-thickness regulator, shaped like a bar and having a rigid surface portion of the curvature radius between 0.5 mm and 15 mm, for regulating the thickness of the developer to be conveyed to the developing zone; and a supporter for supporting the developer layer-thickness regulator.
