Abstract:
A blade of a developing device, for stably supplying a one-component developer to a development roller for carrying the one-component developer on a surface thereof, said blade having elasticity and comprising a linear contact section which is pressed and brought into contact with the surface of the development roller, and an inclined section which extends at an angle from an end of the contact section so as to form a flare at an inflow section of the one-component developer between said blade and development roller,said contact section of said blade being in plane contact with said development roller,said inclined section being formed so that an angle .theta., in the flare at the inflow section, between the inclined section and a line tangent to the development roller at the contact section, has a value that stabilizes an amount of the one-component developer carried on the development rollerwherein the inclined section is formed such that the angle .theta. satisfies 30.degree..ltoreq..theta..ltoreq.60.degree..
