Abstract
A developing device for developing an electrostatic latent image formed on an photoreceptor drum with a dual-component developer, includes: a developing hopper for storing the developer; an agitation roller for conveying the developer while agitating; a developing roller which supplies the developer to a developing area located opposing the photoreceptor drum; a layer thickness-regulating member for regulating the layer thickness of the developer being conveyed by the developing roller; a flow-guide plate for flowing down the surplus developer that was rejected to a position away from the layer thickness-regulating member; a multiple number of partitioning ribs arranged upright on the flow-guided plate for flowing down the surplus developer in a predetermined direction while diffusing the developer with respect to the longitudinal direction of the developer roller; and a downflow direction control mechanism for controlling the downflow direction of the surplus developer regulated by the partitioning ribs.
