    摘要： An image forming apparatus including an image bearing member, a charger, an irradiator, a developing device, a transfer device, a neutralizer, and a varying device is provided. The neutralizer is adapted to neutralize the image bearing member by emitting neutralization light thereto, after a toner image formed on the image bearing member is transferred therefrom. The varying device is adapted to vary an amount of the neutralization light to be emitted to the image bearing member by pulse-width modulation of a voltage to be supplied to the neutralizer. The image forming apparatus satisfies the following formula: f/V>5 wherein f (Hz) represents a frequency of the pulse-width modulation and V (mm/s) represents a linear speed of the image bearing member.

    摘要： A developing apparatus is provided for developing an electrostatic latent image on a latent image carrier by supplying the latent image carrier with a developer. This developing apparatus includes a toner accommodating chamber for accommodating magnetic toners. The apparatus also includes a developing roller, having a plurality of fixed magnetic pole members and sleeves provided along peripheries of the fixed magnetic pole members and rotating thereabout, for feeding the developer composed of magnetic carriers and magnetic toners to the latent image carrier. The apparatus further includes a developing chamber having a partition wall formed along the developing roller and assuming a configuration adapted to a shape of the developing roller, and a toner supply port for supplying the magnetic toners to the developing chamber from the toner accommodating chamber. In another mode of the developing apparatus, the center of each magnetic pole of the fixed magnetic pole members is located in a position deviating from the toner supply port. Further, in still another mode of the developing apparatus, there is employed the magnetic carrier the core of which is iron powder exhibiting strong saturation magnetization.
