DEVELOPING UNIT OF ELECTROPHOTOGRAPHIC APPARATUS ABSTRACT OF THE DISCLOSURE A developing unit is provided for developing an electrostatic latent image formed on an image forming member, by electrostatically adsorbing powder developer onto the latent image. The developing unit comprises a screw (9) provided with paddles or grooves each having a helix angle with respect to an axis of the screw, the screw transferring and supplying the powder developer stored in a developer reservoir to the developing roller; a blade (6) for regulating a layer thickness of the powder developer to be transferred to the image forming member; and a flow regulating plate (7") for biasing a flow of the powder developer, which has been removed by the blade 16) and returning to the developer reservoir due to the gravity action, into a direction opposite to a direction in which the powder developer is transferred by the screw (9). The developing unit further comprises a positioning structure for positioning the developing roller.
