    摘要： A developing device includes: a developing roller incorporating a fixed magnet body having a plurality of magnetic poles in a circumferential direction; a regulating member for regulating an amount of toner on the developing roller by means of a magnetic field formed by the regulating member and the fixed magnet body; and a magnetic-field generating member for scraping off, on an upstream of the regulating member in a rotational direction of the developing roller, toner which is not used for development on the developing roller. A relation Bm/Br>1 is satisfied, where Br represents a magnetic flux density of a distal end portion of the regulating member facing a surface of the developing roller and Bm represents a magnetic flux density of a distal end portion of the magnetic-field generating member facing the surface of the developing roller.

    摘要： A developing device (50) includes a developing sleeve (53) for supplying toner particles (T) to a latent image area (22) on a peripheral surface of a photoconductive drum (20) while rotating about a central shaft (534). The developing sleeve (53) has an immovable sleeve magnet (533) therein. Two magnetic members (82) are disposed in opposite end portions of the developing sleeve (53) and are spaced a predetermined distance from the peripheral surface of the developing sleeve. Each magnet member (82) has an arc shape. A magnetic member magnet (83) is mounted in the magnet member (82) and faces a sleeve magnet (533) so that opposite facing portions of the magnetic member magnet (83) and the sleeve magnet (533) have the same polarity. With this construction, toner particles are prevented from leaking from the end portions of the developing sleeve (53).

    摘要： A developing device includes a container for containing toner, a rotatable shaft provided in the container, a spiral shaped blade formed on an outer circumference of the shaft, and a first spiral member for conveying the toner in the longitudinal direction of the shaft by means of rotation. In addition, a toner removing member is provided for removing the toner attached to the first spiral member. Then, by rotation of the first spiral member, the toner removing member is moved in the longitudinal direction of the shaft and the direction that is orthogonal to the longitudinal direction of the shaft so as to be in contact with the surface of the first spiral member. Accordingly, it is possible to adequately scrape the toner off the spiral shaped blade and the shaft, thereby effectively prevent an aggregation of toner from occurring.
