Abstract (en)
A latent electrostatic image developing device of an image forming machine, comprising a developing roller (53) disposed in a development housing (51) for applying in a developing zone a developer to a latent electrostatic image formed on a photoconductor drum (42), a makeup roller (54) for supplying a developer to the peripheral surface of the developing roller (53) in a developer holding zone, and a developer regulating means (56) for regulating the amount of the developer, held on the peripheral surface of the developing roller (53), in a developer regulating zone. The developing roller (53) is rotationally driven from below to above in the developing zone. The developing roller (53) and the makeup roller (54) are both rotationally driven from above to below in the developer holding zone. The developer regulating means (56) is disposed below the developing roller (53). <IMAGE>
