Claim:
1. A developing device comprising: a developing roller that is disposed to face an image carrier on which an electrostatic latent image is formed, the developing roller being configured to supply toner to the image carrier in an opposing region where the developing roller and the image carrier face each other; a toner supplying roller that is disposed to face the developing roller, the toner supplying roller being configured to supply toner to the developing roller in an opposing region where the toner supplying roller and the developing roller face each other; a regulation blade that is disposed to face the toner supplying roller with a predetermined space therebetween; a casing that accommodates the developing roller, the toner supplying roller, and the regulation blade; a toner receiver support member that is disposed inside the casing so as to face the developing roller or the toner supplying roller between the regulation blade and the image carrier; a toner receiver member that is disposed along a longitudinal direction of the toner receiver support member, the toner receiver member having a toner receiving surface that faces the developing roller and is inclined downward from a said-image-carrier side toward a said-toner-supplying-roller side, the toner receiving surface having a plurality of grooves formed therein to be inclined so as to approach a center part of the toner receiving surface from each end side of the toner receiving surface in a longitudinal direction thereof, from an edge of the toner receiving surface on the said-image-carrier side toward an edge of the toner receiving surface on the said-toner-supplying-roller side; and a vibration generator that vibrates the toner receiver member, wherein such a groove of the plurality of grooves as is formed at a position closest to each end part of the toner receiving surface in the longitudinal direction of the toner receiving surface has a larger inclination of a bottom surface thereof with respect to a horizontal plane than others of the plurality of grooves.
