Abstract
A one-component developing apparatus includes a developing roller which holds a one-component developer and feeds the developer to a photosensitive drum, and a developer layer thickness regulating blade. The regulating blade has an edge which is parallel with a surface of the developing roller and the edge regulates the thickness of the developer layer on the drum. The edge is constructed by being machined along a direction in parallel with the surface of the developer roller. The edge of the regulating blade may be either sharp or rounded.
