Abstract
The present invention provides a method of regulating the thickness of developer layer formed on a developer-transporting means by transporting the layer to a layer thickness-regulating means disposed so as to face with the developer transporting means, pressing the layer by the layer thickness-regulating means so that the layer thickness-regulating distance of the pressing portion between the layer thickness-regulating means and the developer-transporting means can be made substantially equal to the diameter of single developer particle, and allowing the layer to pass through the pressing portion while keeping the layer thickness-regulating distance substantially equal to the diameter of single developer particle.
