    摘要: A developing device in an electrophotographic apparatus, wherein a pole c.sub.1 which is a delivering magnetic pole of the second developing roll for delivering the developer to the first developing roll and a pole d.sub.1 which is a receiving magnetic pole of the second developing roll for receiving the developer from the first developing roll are set so as to be the same in polarity, whereas a pole a.sub.2 which is a receiving magnetic pole of the first developing roll for receiving the developer from the second developing roll and a pole g.sub.2 which is a delivering magnetic pole of the first developing roll for delivering the developer to the second developing roll are set to be equal in polarity, wherein each of an angle between the poles c.sub.1 and d.sub.1 and an angle between the poles a.sub.2 and g.sub.2 is set so as to be in a range of from 70.degree. to 120.degree., and wherein the magnetic flux density of each of a reaction pole induced between the poles c.sub.1 and d.sub.1 and a reaction pole induced between the poles a.sub.2 and g.sub.2 is set so as to be less than or equal to 0.015 tesla.

    摘要: A developing device for use in an electrophotographic apparatus includes a casing for storing a developer including a toner and a carrier therein; a photosensitive drum having a surface on which an electrostatic latent image is formed; a carrying magnetic roll for drawing up the developer stored in said casing; a developing magnetic roll for forming a magnetic brush out of the developer fed by the carrying magnetic roll to develop the electrostatic latent image; and a developer mixing chamber including an impeller interposed between the carrying and developing magnetic rolls, for mixing the toner and carrier contained in the developer with each other, which is drawn up by the carrying magnetic roll, to supply the mixed developer to the developing magnetic roll.
